Green Building Practices on Waste Minimization in China Construction Industry Lee, Bernice Xin Yi Ponraj, Mohanadoss Widyasamratri, Hasti Wang, Jie In China, a common practice for construction waste management is to dispose of it in landfills. A 5% construction waste recycling rate and ongoing insufficient landfilling practice resulted in decreased environmental and socioeconomic well-being. Management hierarchy that starts with rethink, redesign, reduce, reuse, refurbish, recycle, incineration, and finally disposal is a probable strategy to facilitate construction waste minimization in China. The green building concept pursued by China also served as a promising tool in evaluating the performance of Chinese green buildings. Barriers include lack of standard operating procedure in waste minimization, immature recycling technology and an undeveloped recycling market, leading to poor performance in construction waste minimization. Several strategies are proposed to ameliorate the current condition in China's construction sector. Even though results reveal that China falls behind in the engagement of green building compared to developed countries, green materials are utilized in various building structures such as flooring, roofs, walls, and outdoor pavements. Lastly, the benefits and shortcomings of two green material technologies, in particular material selection and recycling, applied in China were reviewed.

Utilization of Moringa oleifera as Natural Coagulant for Water Purification Ng, Meng Hong Elshikh, Mohamed Soliman plant-based natural coagulant; Moringa oleifera seed ; turbidity removal; water purification The plant-based natural coagulant has the potential to substitute the chemical coagulant in the water treatment process. In this work, the potential of plant-based natural coagulants in the ability of turbidity removal was identified. The Moringa oleifera seed was selected for the batch analysis test such as pH, contact time, agitation, and dosage. The high alkaline water decreases the effectiveness of plant-based natural coagulants. The agitation and contact time show the importance of the coagulation process. The optimum turbidity removal rate in pH is 4, the contact time is 60 seconds and 3000 seconds for coagulation and flocculation, respectively, the agitation is 300 RPM and 30 RPM for coagulation and flocculation, and lastly, the dosage is 10 g of Moringa oleifera seed. Finally, the plant-based natural coagulants demonstrated the ability to remove turbidity and could be used in place of chemical coagulants.

Sustainable Technology in Developed Countries: Waste Municipal Management Hoareau, Carol Emilly Ahmad, Noraziah Nuid, Maria Rubiyatno Khoi, Dao Nguyen Kristanti, Risky Ayu As more studies were conducted and global events unfold, a greater emphasis is being placed on the importance of preserving the Earth's natural resources and cycles before we face a catastrophic climate crisis. Thus, developed countries are constantly adapting their policies and legislation to promote green development for the sake of sustainable development, which benefits both the environment and the socioeconomic segment. As populations grow and living standards improve, more waste is generated. Appropriate municipal waste management is necessary to avoid harm to the environment, wildlife, and human health. Sustainable municipal solid waste management is even included in the United Nations' (UN) Sustainable Development Goals, which aim to improve the world's environment and economy. The European Union (EU) member states' waste management systems can be considered exemplary. In some countries, landfills have been prohibited, promoting the use of more sustainable technologies such as organic waste incineration, recycling, and composting. However, a divide exists between member countries, with some lagging behind in terms of waste management strategies. Thus, this paper examined the current state of municipal waste in EU member states, followed by a review of the various disposal technologies implemented. The difficulties and environmental concerns that must be overcome are discussed, as are the recommendations and possible future directions.

Scenario of Municipal Waste Management in Malaysia Liew, Zachary Raphael Monir, Minhaj Uddin Kristanti, Risky Ayu Malaysia has rapidly modernized, with most of the population now residing in cities and the remainder in rural or remote areas. The amount of municipal solid waste generated has increased in tandem with the country's rapid urbanization in response to that statement. Due to a lack of connectivity in rural areas, there may be insufficient infrastructure for a proper waste management system. As a result, illegal waste dumping was common, and landfills' massive volumes of waste may contribute to greenhouse gas emissions. The Malaysian government has responded by taking the necessary steps to upgrade the country's current waste management system in order to better manage municipal solid waste disposal. This research looks at how energy recovery from accumulated waste can be used as a renewable energy source, as well as the current issues, challenges, and proposed solutions. Methane gas produced as a byproduct of waste decomposition in landfills or disposal sites was used to generate electricity more efficiently and sustainably, resulting in a positive economic and environmental outcome.

Malaysia Moving Towards a Sustainability Municipal Waste Management Tang, Yien Yu Tang, Kuok Ho Daniel Maharjan, Amit Kumar Abdul Aziz, Azrina Bunrith, Seng The elevation of waste generation subsequent to population growth has become a severe environmental topic in Malaysia. Since most of the waste is being dumped into a landfill, the open dumpsite, or unsanitary landfills which are not constructed with proper engineering plan, severe impacts on the environment result. The energy demand in Malaysia increased with the growing population, but reliance on fossil fuels to generate electricity has created another greenhouse gas contributor. Alternatively, waste-to-energy technology solves the problem of increasing waste by converting the waste to a renewable energy source. Malaysia has moved towards landfill gas recovery system and incineration for waste energy recovery. The recovery system and refuse-derived fuel plant achieved expectation; however, the incineration plants have failed due to the opposition of the public, lack of funding and technician expertise, and other technical issues. The solid waste management practices lacking separation and recycling sources, become an obstacle for development. The government puts effort into solving the current issue by promoting recycling in the public, enforcing the legislation, and approaching new technologies for better solid waste management practice in the future. This paper aims to discuss the application of energy recovery from municipal solid waste in Malaysia.

Tolerance of Earthworms in Soil Contaminated with Polycyclic Aromatic Hydrocarbon Rubiyatno Teh, Zee Chuang Lestari, Diah Velentina Yulisa, Arma Musa, Muthah Chen, Tse-Wei Darwish, Noura M. AlMunqedhi, Bandar M. Hadibarata, Tony Removal, wild earthworm, pyrene, soil. Pyrene is a very resistant polycyclic aromatic hydrocarbon (PAH) with four benzene rings that survives in the environment. This study was aimed at investigating the tolerance of earthworms in soil contaminated with pyrene. The studies were performed by employing earthworms gathered from shady regions adjacent to sewage ponds as pyrene degraders to eradicate pyrene from the soil. Numerous factors affecting pyrene degradation efficiency were explored, including the effect of contaminant concentration, earthworm and soil ration, and soil condition. The highest pyrene removal (31.2%) was shown by earthworms in the condition of soil mixed with cow dung. Pyrene decomposition was inhibited during soil sterilization due to the absence of soil microorganisms and indigenous pyrene-degrading bacteria. Nonetheless, earthworms are suitable for use as pyrene degraders in contaminated soil.

Removal of Cresol Red by Adsorption Using Wastepaper Salman, Mohamad Demir, Muslum Tang, Kuok Ho Daniel Cao, Linh Thi Thuy Bunrith, Seng Chen, Tse-Wei Darwish, Noura M. AlMunqedhi, Bandar M. Hadibarata, Tony Recycling waste papers, decolourization, weight, adsoprtion, cresol red dye The utilization of less expensive and more effective adsorbents derived from a variety of basic materials has been investigated. The research aimed to investigate the feasibility of employing waste paper as the adsorbent to remove the cresol red (CR) dye from wastewater through adsorption mechanism. Langmuir, Jovanovic, and Freundlich model were observed for isotherms models, while pseudo-first-order and pseudo-second-order were examined for kinetic models. The results indicated that increasing the adsorbent dose and contact time gave no significant effect to adsorption capacity while adsorption capacity increased with the increasing of pH until it reached a maximum at pH 8, and raising the starting dye concentration leads in a significant increase in adsorption capacity (16.7 mg/g). When the experimental adsorption isotherms and kinetic were fitted using the Freundlich models and pseudo-second-order model, it was discovered that those models were more accurately represented by the data, as indicated by a high correlation coefficient (R2) of 0.974 and 0.963.

Study of Household Waste Management and Recycling Awareness Between Residential Areas in Kuala Nerang, Kedah, Malaysia Abdul Halim, Husna Mohamed Najib, Mohamed Zuhaili Zainal Abideen, Muzaffar Basri, Hazlami Fikri Muda, Khalida household waste management; segregation of solid waste; recycling awareness This paper presents a study on household waste management and recycling awareness. Residential areas are the major sources of solid waste as that is where people live. The waste that is usually disposed of from residential areas includes food waste, plastic waste, paper, glass, tin, and others. The increasing trend in waste generated from homes has become a major concern. This study aimed to assess household waste management and recycling awareness in two residential areas located in Padang Terap District, Kuala Nerang, Kedah, Malaysia. Recently, Padang Terap district showed an increase in waste generated compared to another district, Kedah. An open-ended questionnaire was distributed to approximately 32 respondents, and an interview was conducted to study household waste management and recycling awareness in two residential areas—Taman Jati and Taman Pelangi. The research shows that household waste management to segregate the waste remains a problem, despite most respondents being aware of this issue through different media. Furthermore, the lack of household waste management and recycling programs and facilities by the local authorities caused residents to be reluctant to practice these activities.

Effect of Substrate-to-Inoculum Ratio and Temperatures During the Start-up of Anaerobic Digestion of Fish Waste Yulisa, Arma Chairattanawat, Chayanee Park, Sang Hyeok Jannat, Md Abu Hanifa Hwang, Seokhwan Anaerobic digestion F/M ratio Fish waste Mono-digestion Start-up The high protein and lipid content of fish waste makes mono-digestion a difficult bioprocess for an anaerobic digestion (AD) system. On the other hand, the massive increase in fish and seafood consumption worldwide has led to an inevitable fish waste mono-AD. Therefore, this study was conducted to investigate the effects of food-to-microorganisms (F/M) ratios and temperatures during the start-up period of fish waste mono-digestion. F/M ratios of 0.5, 1, 2, and 3 on a g-COD/g-VSS basis were operated at 35°C and 45°C, representing mesophilic and hyper-mesophilic conditions, respectively. The increase in F/M ratio improved the maximum methane (CH4) production rate at both temperatures. However, F/M ratio of 0.5 generated the highest CH4 yield in mesophilic and hyper-mesophilic conditions (0.23±0.00 L-CH4/g-CODinput). Further increase in F/M ratio decreased CH4 yield up to 21.74% and 39.13% when the reactors were operated at 35°C and 45°C, respectively. When reactors were supplied with FM ratios of 0.5, 1, and 2, hyper-mesophilic temperature improved methanogenesis by up to 2.61% and shortened the lag phase by 22.88%. Meanwhile, F/M ratio 3 at 45°C decreased cumulative CH4 production by up to 26.57% and prolonged the lag phase by 10.19%. The result of this study is beneficial to managing the input substrate of a batch-AD system that treats fish waste as a sole substrate.

Biosorption of Synthetic Dye by Macrofungi Lee, Kek Kin Kristanti, Risky Ayu Yulisa, Arma Rubiyatno Ningsih, Fitria Syafrudin, Muhammad Hernandes, Erika Albescu, Mihaela Biosorption; Remazol Brilliant Blue R; biosorbent; decolourization; Pleurotus ostreatus This research project aimed to provide an environmentally friendly method for the decolorization and biosorption of synthetic dye by utilizing fungi as biosorbents. The study was carried out by first growing the fungi in solid medium and then using the fungi as biosorbent to absorb dye in aqueous solution. In the first stage, screening experiments were carried out among 5 different types of fungi, and Pleurotus ostreatus was determined to have the highest growth rate. The Pleurotus ostreatus was recultivated with Remazol Brilliant Blue R dye to determine its dye removal ability. Pleurotus ostreatus sp. exhibited vigorous dye decolorization in agar medium within 2 days. By carrying out batch analysis, 4 parameters were examined, which were the effect of pH, surfactant concentration (Tween 80), salinity concentration and dosage of biosorbent. The results showed that the maximum dye decolourization by Pleurotus ostreatus can be achieved through establishing an acidic condition of pH 2, addition of 0.1mL of Tween 80, 0mg/l of sodium chloride concentration, and dosage of 8 plugs. Lastly, the experimental data was found to fit the Jovanovic Isotherm the most. In conclusion, Pleurotus ostreatus is capable of decolourizing and adsorbing dye particles in the dye aqueous solution.

The Effects of Effluents’ Discharge from Some Paint Industries on Soil’s Physicochemical Properties and Bioattenuation of Polluted Soil Chukwuma, Okafor Ugochukwu Uchenna, Orji Michael Ogonna, Umeh Sophina Chinedu, Onuorah Samuel Heavy metals, Paint Effluents, Monitored natural attenuation, Soils, Autochthonous Microorganisms Rapid population growth resulting in industrial proliferation and urbanization has led to the rapid increase in pollution of the environment. Paint industries in urban areas mostly channel their wastewater into streams and on land, which results in the pollution of the receiving environment. This study aims to determine the impact of effluent discharges from paint industries on the soils’ physicochemical properties and the clean-up of the polluted soil through monitored natural attenuation. Composite samples of paint-effluents and soils were collected from paint industries. Their bioattenuation levels and changes in their physicochemical properties were monitored over a six-month period. Fungal isolates from the effluents include Saccharomyces cerevisiae (20%), Rhodotorula species (15%), Aspergillus niger (25%), Aspergillus flavus (15%), and Penicillum notatum (25%), while the bacterial isolates include Staphylococcus aureus (30%), Bacillus sp. (20%), Klebsiella sp.(15%), Escherichia coli (15%), Salmonella sp. (10%), and Staphylococcus species (10%). The effluents showed slightly alkaline pH values while the soils showed slightly acidic pH values. There were significant reductions in the heavy metal contents of the effluent polluted soils as remediation time increased, thus reducing the toxicity of such soil environments. Monitored natural-attenuation methods should be employed and improved as a means of reducing the toxicity of effluents on the environment since they are cheap and effective compared to other methods.

Evaluation of Agricultural Waste Management Mechanism in Iran Zargaran Khouzani, Mohammad Reza Dehghani Ghahfarokhi, Zahra agricultural waste, compost, air pollution, greenhouse gases The unfavourable situation of waste management in Iran can be seen in different sectors, and agriculture is not excluded from these sectors. The wastes of the agricultural industry can be used in a beneficial way in various agricultural applications and other industrial processes. However, the cost of collection, processing, and transportation can be much higher than the income from the beneficial use of such waste. Incineration of crop residues creates numerous environmental problems. The most important side effects of burning crop residues include the emission of greenhouse gases that lead to global warming, air pollution, and things like soil degradation, loss of soil fertility, loss of beneficial microorganisms, intensification of soil erosion, etc. In the current research, which is a review based on library sources, the mechanism of agricultural waste management in Iran has been evaluated. There are other consequences of such actions. The criteria for action are laws regarding the burning of product residues in Iran, the most important of which are the Waste Management Law and the Clean Air Law. Among these methods are sustainable management methods for product residues, including compost production, biochar production, and waste management at the production site.

Medical Waste during COVID-19 Pandemic: Its Types, Abundance, Impacts and Implications Tang, Kuok Ho Daniel COVID-19 incineration masks protective equipment packaging plastics COVID-19 has resulted in an abrupt and significant increase in medical waste, albeit with improving air and water quality in certain regions. This paper aims to review the types, abundance, and impacts of COVID-19-related medical waste through examining the contents of 54 peer-reviewed scholarly papers. COVID-19-related medical waste compositions vary over time, with COVID-19 screening, diagnostic, and treatment wastes, as well as used personal protective equipment (PPE), constituting the majority of medical waste at the start, followed by vaccination waste during the peak of vaccination. COVID-19-related medical waste is expected to decrease and steady as more and more countries relax restrictions in an attempt to live with COVID-19. Geographically, the amount of COVID-19-related medical waste depends on population size, with highly-populated countries and cities such as China, Manila, Jakarta, and Bangkok seeing or expected to see a hike in the waste of between 210 tonnes/day and 280 tonnes/day during COVID-19. Packaging of the medical and PPE items forming the medical waste stream also contributes to a substantial amount of waste. As plastics are a major component of medical waste, the increase in COVID-19-related medical waste and its mismanagement have worsened environmental pollution caused by plastics. The surge of medical waste during COVID-19 strained the existing medical waste disposal systems, and incineration of the waste contributed to air pollution, which was often localized. Mismanagement of the waste could also raise public health concerns and cause visual repercussions.

Mean of total content (mg/kg) and percentage bioavailability were: As 470.48±48 (31.16%), Cu 62.95±10.61 (29.02%) and Zn 125.58±20.74 (26.67%), respectively. Analysis of variance and correlation analyzes indicated that soil pH, % clay, % organic carbon, cation exchange capacity, and metal speciation in soil control metal mobility and bioavailability in the poultry farm soil. The mean contents of As, Cu and Zn in soil in the sampling area were usually more than those of the control site, indicating some degrees of contamination of the poultry farm soil by these metals. Also, the mean contents of As in some zones were considerably greater (p Tecno Scientifica Publishing 2022-10-25 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://tecnoscientifica.com/journal/idwm/article/view/119 10.53623/idwm.v2i2.119 Industrial and Domestic Waste Management; Volume 2 - Issue 2 - 2022; 84-99 2809-4255 10.53623/idwm.v2i2 eng https://tecnoscientifica.com/journal/idwm/article/view/119/98 Copyright (c) 2022 Taiwo Olusegun Ogunwale, John Adekunle O.

Evaluation of Heavy Metals Found in Vegetables of Some Poultry Farms in Osun State, Nigeria Ogunwale, Taiwo Olusegun Oyekunle, John Adekunle O. Ogunfowokan, Aderemi Okunola Oyetola, Simoen Oyesoji Environmental monitoring, health impact, poultry inputs, soil contamination, vegetables, heavy metals Heavy metals are persistent in the ecosystem and are held responsible for natural accumulation at all feeding levels. Nevertheless, contact does not occur just because of the availability of a contaminant material in the ecosystem. This present work was aimed at evaluating the contents of heavy metals in vegetables sampled from some poultry farms in Osun State. Five vegetables, namely green vegetable, bitter leaf, gruty-stalked jatropha, scent leaf, and water leaf, were tested for heavy metals, such as arsenic, cadmium, copper, iron, lead, and zinc, using a flame atomic absorption spectrophotometer following wet digestion with HNO3. Quality assurance techniques included blank testing, recovery testing, and calibration of concentrations. Descriptive statistics were used for data interpretation. The analytical results signified that those heavy metals were detected in all the vegetables from the various sites. Most of the contents are below the Food and Agriculture Organization/World Health Organization safe range in the vegetable section, with the exception of A. Drastic measures should be adopted to avoid the use of such health-toxic contents of metals in poultry feed. So, it was suggested that there should be constant monitoring of poultry sites to control, limit, and stop heavy metal contamination once and for all.

Driving Forces on Household Solid Waste Management Behaviors: A Research for the City of Izmir, Türkiye Guven, Elif Duyusen Akinci, Gorkem Temel, Dilara The proper solid waste recycling process starts at the houses with the attendance of the individuals. The presented study includes comprehensive research on the individuals’ shopping and waste generation behaviors, awareness of waste management issues, readiness and willingness for source separation, and their self-evaluation and self-annoyance about waste generation. The current study was conducted by administering a detailed questionnaire to 300 people in Zmir, Türkiye's third largest city. The relationships between the answers given and the main factors affecting waste production were determined statistically. Principal component analysis (PCA) identified the key drivers of public behavior associated with waste generation and separation at the source. Through environmental sensitivity, including proper waste management behaviors, age is discovered to be a significant factor. Family phenomena, including stable life and family budgets (32.58%), awareness of people about their inappropriate and disproportionate behaviors towards consumption and waste generation (21.28%), and the impositions of urban life (9.37%) were found to be the major factors influencing waste management habits.

Heavy Metals in the Soil Around a Cement Company in Sokoto, Northwestern Nigeria Pose Health Risks Yahaya, Tajudeen Umar, Abdulrazak Abubakar, Muddassiru Abdulazeez, Abdulmalik Musa, Bilyaminu Ibrahim, Yusuf Carcinogenic risk Cement Hazard quotient Heavy metals Lead Cement is widely used in the building industry because it is reliable and because its basic ingredients are inexpensive and abundant. However, the production of cement produces heavy metal-laden dust that can harm humans and the environment. This study aimed to determine the risk posed by heavy metals in the soil around a cement company in Sokoto, Nigeria. Soil samples were obtained at 0.1, 0.5, and 1.0 km from the company and served as test samples, while control samples were obtained at 5.0 km away. The soil samples were treated and assayed for lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) using atomic absorption spectroscopy. The values obtained were used to estimate the heavy metals’ average daily inhalation (ADI), average daily dermal exposure (ADDE), hazard quotient (HQ), health risk index (HRI), and carcinogenic risk (CR). Permissible levels of all the heavy metals were detected at all the locations (0.1 > 0.5 > 1.0 > 5.0 km). However, the ADI, ADDE, HQ, HRI, and CR of the heavy metals were above the permissible limits. It can be inferred from the results that the soil around the company can predispose humans to heavy metal toxicities. Consequently, the company needs to prioritize pollution control.

The Impact of Process Variables on the Quantity and Quality of Biogas Generated from Anaerobic Digestion of Food Waste and Rumen Contents Amoo, Afeez Oladeji Ahmed, Sabo Haruna, Adamu Anaerobic digestion; cleaning system; process factor; biogas; carbondioxide This research aimed to investigate how combining process variables affects biogas production from anaerobic digestion of food waste and rumen contents. A mixture design was used to evaluate the effects of temperature, pH, agitation frequency, and retention time on biogas quantity and quality. Anaerobic mono-digestion and co-digestion were performed using 2 liter single-stage plastic anaerobic digesters. Cumulative biogas volume and its composition, including carbon dioxide, hydrogen sulphide, moisture, and methane content, were estimated volumetrically. The highest biogas volume and quality were obtained under the following conditions: food waste (0.30 kg), rumen content (0.30 kg), water content (0.40 kg), temperature (34.0° C), pH (9.0), agitation frequency (4 times/day), and retention time (32 days). Combining process variables can significantly impact biogas quantity and quality, and optimal process parameters vary depending on the substrate and operational conditions. Anaerobic digestion can effectively manage organic waste, produce renewable energy, and mitigate greenhouse gases.

Municipal Wastewater Treatment Technologies in Malaysia: A Short Review Kristanti, Risky Ayu Bunrith, Seng Kumar, Ravinder Mohamed, Abdelrahim Omar Activated sludge process; membrane bioreactor, moving bed biofilm reactor; municipal wastewater The aim of this study was to evaluate different municipal wastewater treatment technologies for commercial use and develop an optimized system for a case study plant and future plant designs. Municipal wastewater, classified as a low-strength waste stream, can be treated using aerobic and anaerobic reactor systems or a combination of both. Aerobic systems are suitable for low-strength wastewaters, while anaerobic systems are suitable for high-strength wastewaters. Malaysia has actively implemented various wastewater treatment technologies to address the increasing demand for clean water and reduce environmental pollution. Some commonly used technologies in Malaysia include Activated Sludge Process (ASP), Membrane Bioreactor (MBR), and Moving Bed Biofilm Reactor (MBBR). These technologies show promise in removing emerging pollutants, such as pharmaceuticals and personal care products, which are not effectively eliminated by conventional treatment methods. Additionally, Malaysia could consider investing in renewable energy sources like solar and wind to power wastewater treatment plants, thereby reducing reliance on non-renewable energy and supporting sustainable development. It is also important to emphasize continued public awareness and education initiatives to promote responsible wastewater disposal practices and environmental stewardship.

Exploring the Potential of Composting for Bioremediation of Pesticides in Agricultural Sector Lau, Yu Yan Hernandes, Erika Kristanti, Risky Ayu Wijayanti, Yureana Emre, Mehmet Pesticides; sources; fate; impacts; challenges; composting The rapid expansion of the human population has raised the chemical stress on the environment due to the increased demand of agricultural yields. The use of pesticides is the primary contributor to environmental chemical stress, which is essential for agricultural expansion in order to produce enough food to sustain the burgeoning human population. Pesticide residues in soil have grown to be a subject of rising concern as a result of their high soil retention and potential harm to unintended species. Diverse remediation strategies, such as physical, chemical, and biological, for limiting and getting rid of such contaminants have been put forth to deal with this problem. Bioremediation is one of these techniques, which has been deemed the best for reducing pollution because of its low environmental impact, simplicity of operation and construction. Microorganisms are implemented in this technique to break down and get rid of toxins in the environment or to reduce the toxicity of chemical compounds. This study thoroughly analyses the different composting soil remediation methods, including landfarming, biopiles, and windrows, to reduce and eliminate soil pollution. Although biological treatment is the best option for cleaning up polluted soil, it is still important to evaluate and review the approaches over the long term to determine whether they are effective in the field. It is because the reactivity of the microorganisms is highly dependent on environmental parameters, and the contemporary environment is characterised by unpredictable weather patterns, localised droughts, and temperature fluctuations.

Phytoremediation of Microplastics: A Perspective on Its Practicality Tang, Kuok Ho Daniel accumulate adsorb microplastics phytoremediation rhizosphere translocation Microplastics have permeated all parts of the environment, rendering their removal essential. Numerous strategies ranging from the physical removal of mismanaged plastic items to the biodegradation of microplastics with microorganisms and biocatalysts have been proposed to alleviate microplastic pollution. Phytoremediation is one of the plastic-removing strategies, but it has not received much attention. This perspective paper aims to review the phytoremediation of microplastics and discuss its practicality. The paper shows that plants could act as interceptors and a temporary sink of microplastics by facilitating their deposition, adsorbing them, trapping them in the root zone, enabling them to cluster on the roots, taking them up, translocating them, and accumulating them in various plant parts. However, there was a lack of evidence pointing to the degradation of microplastics after they were adsorbed, taken up, and stored. Weak adsorption and environmental factors may cause the trapped microplastics to desorb, resuspend, or evade, thus also making plants a source of microplastics. The microplastics trapped and accumulated in plants may be transferred to the higher trophic levels of the food chain through ingestion and raise concerns over their ecotoxicities. Unlike localized pollution, microplastic pollution is widespread, which limits the applicability of phytoremediation. Besides, microplastics could adversely impact plant health and the ability of plants to remove other environmental pollutants. These drawbacks may reduce the attractiveness of phytoremediation unless it can be effectively combined with bioremediation to degrade microplastics.

Bioremediation of Pesticide-Contaminated Soils through Composting: Mechanisms, Factors, and Prospects Wong, Wei Lin Pangging, Monmi Rubiyatno Composting; bioremediation; pesticide; contaminated soil Pesticide contamination of soils poses a significant environmental and agricultural challenge on a global scale, with escalating pesticide consumption in various regions. Composting has emerged as a cost-effective and sustainable bioremediation method for pesticide-contaminated soils. This review article delves into the mechanisms, factors influencing efficiency, and the pros and cons of composting as a strategy to address pesticide pollution in soils. Pesticides enter soil environments through both point sources, such as spillage from storage or disposal areas, and non-point sources, including intensive agricultural use and household applications. The physical and chemical characteristics of pesticides, coupled with soil factors like permeability and particle size, influence their fate and behavior in soils. Composting, as a bioremediation method, offers several advantages, including complete destruction of pesticide compounds through microbial degradation, transforming them into less hazardous products. Key factors affecting composting efficiency include nutrient availability, particle size, temperature, pH, oxygen, and moisture content, all crucial for microorganism growth and pesticide degradation. This article underscores the importance of maintaining optimal conditions for these factors to ensure the high performance and efficiency of pesticide degradation during composting. It also discusses the potential drawbacks of this method. Composting proves to be a promising and eco-friendly approach for remediating pesticide-contaminated soils, addressing both environmental concerns and the need for sustainable agricultural practices.

Sustainable Energy from Waste: A Feasibility Study in Miri, Malaysia Chua, Ming Xuan Hashim, Nur Hasyimah Downmore, Musademba Gani, Paran The growth of urban populations, industrialization, and economic development has led to a surge in solid waste production. When local recycling infrastructure falls short, much of this waste ends up in landfills, causing environmental and social challenges. This study aims to assess the feasibility of converting municipal solid waste (MSW) into energy, with a focus on combustion chamber modeling in Miri, Sarawak. Data on MSW composition are obtained from secondary sources. Ansys Fluent software is used to model the combustion chamber, and simulations are conducted to explore temperature, turbulence, and species distribution. MSW composition illustrates higher substantial fractions, with 39.8% being food waste, followed by 20.7% plastic/rubber. Calorific values range from 4652 kJ/kg for food waste to 32564 kJ/kg for plastic/rubber. Combustion simulations result in maximum flue gas temperatures of 1500 °C, 1200 °C, and 1800 °C under varying air inlet conditions. Turbulence intensities on the grate range from 125% to 174% for these air inlet configurations. The study concludes that moisture content significantly affects calorific value and heat generation during combustion. Higher turbulence intensities lead to increased reaction rates and heat generation, improving the energy efficiency of the process.

Health Risk Assessment of Heavy metals, Physicochemical properties and Microbes in Groundwater near Igando Dumpsite in Lagos, Nigeria Yahaya, Tajudeen Chidi, Okeke Abdulrahman, Sani Oladele, Esther Abdulrakib Abdulrahim Abdulganiyu, Yunusa Izuafa, Abdulrazaq The most common and cost-effective waste disposal method is the dumpsite; however, leachate from dumpsites may percolate and compromise groundwater sources. This study evaluated the levels of heavy metals (lead, cadmium, chromium, copper, and arsenic), physicochemical parameters (pH, electrical conductivity, total dissolved solids, hardness, calcium, magnesium, and chloride), and microorganisms in borehole water samples obtained at distances of 50, 100, 200, and 400 meters from the Igando dumpsite in Lagos, Nigeria. The health hazards associated with the heavy metals were also calculated. Physicochemical analysis indicated that the water samples were acidic, with pH values ranging from 4.30±0.01 to 5.21±0.008. They contained levels of calcium (166.73±0.01 - 328.66±0.06 mg/l), magnesium (83.72±0.02 - 119.40±0.17 mg/l), hardness (416.01±0.11 mg/l - 820.00±1.63 mg/l), and chloride (20.07±0.02 - 120.90±0.81 mg/l) that exceeded the limits set by the World Health Organization. Heavy metal analysis showed that, in all locations, lead exceeded the permissible limits, cadmium exceeded the limits except for the 400-m location, and copper, chromium, and arsenic (except for the 50-m location) were within permissible limits. The average daily intake and hazard quotient of the heavy metals were both within recommended limits, but the carcinogenic risks of lead, cadmium, and copper in water collected at a distance of ≤100m exceeded the threshold. Microbiological examinations revealed non-permissible levels of bacteria at all locations, coliforms at the 400-m location, and fungi at the 50-m and 400-m locations. On average, the parameters significantly (p<0.05) increased in concentrations as the proximity to the dumpsite decreased. These findings indicate that borehole water is not suitable for drinking without treatment.

Managing Household Waste Through Transfer Learning Kunwar, Suman Garbage Classification Transfer Learning Deep Learning Waste Management Carbon Emission As the world continues to face the challenges of climate change, it is crucial to consider the environmental impact of the technologies we use. In this study, we investigate the performance and computational carbon emissions of various transfer learning models for garbage classification. We examine the MobileNet, ResNet50, ResNet101, and EfficientNetV2S and EfficientNetV2M models. Our findings indicate that the EfficientNetV2 family achieves the highest accuracy, recall, f1-score, and IoU values. However, the EfficientNetV2M model requires more time and produces higher carbon emissions. ResNet50 outperforms ResNet110 in terms of accuracy, recall, f1-score, and IoU, but it has a larger carbon footprint. We conclude that EfficientNetV2S is the most sustainable and accurate model with 96.41% accuracy. Our research highlights the significance of considering the ecological impact of machine learning models in garbage classification.  Tecno Scientifica Publishing 2024-03-25 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://tecnoscientifica.com/journal/idwm/article/view/408 10.53623/idwm.v4i1.408 Industrial and Domestic Waste Management; Volume 4 - Issue 1 - 2024; 14-22 2809-4255 10.53623/idwm.v4i1 eng https://tecnoscientifica.com/journal/idwm/article/view/408/208 Copyright (c) 2024 Suman Kunwar https://creativecommons.org/licenses/by/4.0

This study looked at the private garbage contractors' methods of operation, clientele, and difficulties in managing residential solid waste in Ibadan, Nigeria. In the three local government districts of the metropolis, a structured questionnaire was given to 21 private refuse operators and 250 homes. A few measures of service quality were employed to determine the method of operation and customer base. To interpret the gathered data, both descriptive and inferential statistics were employed. The findings showed that the factors that affected residents and operators of SWM the most were educational attainment, monthly income, building types, and occupation (n = 213, 85.2%; 164, 65.6%). Of the houses who enrolled for waste collection, between 201-300 (47.6%) and 100-200 (42.9%) utilized private waste contractors. Although the license specifies once per week, waste collection is inconsistent and typically occurs once every two weeks (52.4%); charges, on the other hand, are variable and exceed the established rates. Undue financial backing from the LGAs, impassable areas, incompatible law, poor advertisement and awareness, political influence, exorbitant leachate treatment fees, and poor health were among the operational issues confronted the private garbage operators. The elements that affect the way the private sector of SWM operates and attracts customers were found to be as follows: non-cooperation of residents (n = 8, 38.1%), poor nearness to buildings (n = 9, 42.9%), and the lax enforcement of hygiene regulations (n = 4, 19.0%). The report suggests that in order to provide residents in Ibadan Metropolis with high-quality services, private refuse operators should regularly monitor and oversee the collection of solid waste.

Enhanced Soil Decontamination via Electrokinetic Removal of Organic Pollutants Ngieng, Hui Yee Jusoh, Muhammad Noor Hazwan Ahmad, Noraziah Al Masud, Md Abdullah Samaraweera, Hasara Mohamed, Mohamed Mostafa Soil Pollution; Electrokinetic; Organic Contaminants; Remediation Technique; Surfactants; Bioremediation Soil pollution is one of the concern issues in the Asia region. Soil acts as a shelter for underground microorganisms and provides nutrients for plants. Most of the organic contaminants are sourced from agriculture and industrial areas. Organic contaminants which are volatilized and immiscible lead to air and water pollution. Electrokinetic remediation is a technology that has been developed for soil remediation since a few decades ago. It is not fully developed and is still under investigation. Electrokinetic remediation is being applied to improve the removal efficiency of organic contaminants which exist in low hydraulic conductivity of soil or fine-grained soil.  Generally, a low direct current, 1DCV/cm is applied. Facilitating agents including surfactant and co-solvent combined with electrokinetic remediation eliminated more organic contaminants compared with electrokinetic remediation alone. Electrokinetic remediation with the addition of bioremediation or phytoremediation process manipulates the transportation of organic contaminants in soil to increase the efficiency of remediation technologies. Electrokinetic remediation is recommended due to its flexibility, cost-effectiveness, and safety. One of the drawbacks is low effectiveness in removing non-polar organic pollutants due to weak desorption capacity and poor solubility in water. Co-solvents and surfactants can be introduced as alternatives to enhancing the solubility of non-polar pollutants and reducing surface tension, which improves their mobility within the soil matrix. These facilitating agents help improve the overall effectiveness of electrokinetic remediation, particularly for challenging contaminants.

Soil Washing Methods for Effective Removal of Heavy Metal Contaminants Chiu, Jian Chong Gani, Paran Soil pollution caused by heavy metals from anthropogenic activities poses a significant environmental and health threat globally. Traditional remediation methods like solidification/stabilization have limitations, prompting the need for alternative techniques. Soil washing emerges as a promising approach, employing physical and chemical methods to effectively remove contaminants. This paper explores soil washing methods, focusing on sites contaminated with heavy metals such as zinc, lead, nickel, mercury, arsenic, copper, chromium, and cadmium, particularly influenced by military and industrial activities. Several techniques, including physical separation and chemical extraction, are discussed, which consider a few factors such as magnetism, density, size, and hydrophobicity to concentrate metal contaminants and solubilize soils. Physical separation targets particulate contaminants, while chemical extraction addresses non-detrital metals or soils with adsorbed ionic forms. The study also analyses field applications of soil washing systems and the implementation of remediation techniques. It emphasizes the need for innovative soil remediation strategies to mitigate the adverse effects of heavy metal contamination on soil quality and human health.

Effect of Different Sizes and Heights on the Removal Efficiency of Composite Clay Filter for Gold Mine Site Wastewater Remediation Olatunji, Abass Adekunle Ayanshola, Ayanniyi Mufutau Ajala, Mary Adejoke Erhuanga, Ebelechukwu clay ceramic filter wastewater remediation flow rate removal efficiency gold mine site Wastewater from mining-related activities contains toxic elements that require remediation, and most available wastewater filters have inconsistent flow rates and removal efficiency due to their thickness. This study, therefore, examined the effect of height and size on the flow rate and removal efficiency of a clay composite filter for wastewater remediation. The developed clay filter and its composites were characterized using various techniques such as X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The XRF analysis showed that the clay contained 91.38% major minerals, including iron oxide (Fe2O3), aluminum oxide (Al2O3), and silica (SiO2), which could enhance the filtration process. Additionally, FTIR revealed that both the clay and the filter are rich in functional groups, including kaolinite and illite, which could promote the filtration process. Further analysis showed that the filters had an average adsorption rate of 87.32%, an average flow rate of 0.891 L/hr, and an average removal efficiency of 99.6%. An increase in the height of a small-diameter filter resulted in a 0.21% increase in removal efficiency, while for larger diameters, the removal efficiency decreased by 0.11%. Conversely, increasing the diameter of a short filter increased the efficiency by 0.25%, while for taller filters, the removal efficiency decreased by 0.07%. Therefore, this work demonstrated that both height and diameter have noticeable effects on flow rate: as height increases, flow rate decreases, and as diameter increases, flow rate increases. The filter's efficiency is somewhat affected by both height and diameter, with a small increase in efficiency noted at greater heights and a slight decrease in efficiency noted at larger diameters.

Oyedare, Adekunle Benjamin Oyetola, Simeon Oyesoji Oluwalana, Ayodeji Isaac Basiru, Taofeek Adekola Ogungbile, Peter O. Balogun, Francis Adeniyi Oduah, Oluwaseun Adewunmi Ogunrinola, Oluwaseun Femi micro and small firm; household waste; solid waste management; waste impact; Ibadan metropolis Given the current rate of urbanization, municipalities in most Nigerian cities have struggled with the collection, transportation, and disposal of solid waste. This is due to waste generation, both residential and commercial, occurring in a dispersed manner across homes, buildings, streets, parks, and even vacant spaces within communities. This manuscript aims to evaluate the state of municipal solid waste management in Ibadan, household solid waste storage practices, and the locations of solid waste storage containers (skip points) in relation to accessibility and health risks to the community, in accordance with Nigerian National Solid Waste Management Standards and other pertinent international standards. A structured questionnaire was distributed to 21 micro and small firms and 250 homes in each of the three local government areas of the metropolis, with descriptive statistics used to interpret the data. According to the study results, inadequate Municipal Solid Waste Management (MSWM) service delivery in the Ibadan metropolitan area can be attributed to several issues, including a lack of institutional coordination among urban planners. The study’s conclusions indicate that the state of MSWM in the sampled areas is either inadequate or has poor spatial coverage and container utilization. Lastly, the study primarily suggests that these measures can reduce problems associated with MSWM by encouraging public-private partnerships, fostering effective institutional coordination with urban planner consultants in MSWM and skip-point location, and motivating the community to adopt integrated sustainable Solid Waste Management (SWM) strategies.

Effect of Different Biomass Levels of Eichhornia crassipes and Pistia stratiotes on Nutrients, Organics, and Heavy Metals Removal from Wastewater Ajiboye, Adewale V. Badmos, Babajide Adelodun, Adedeji A. Babatola, Josiah O. This study investigates the impact of varying biomass levels of Eichhornia crassipes (water hyacinth) and Pistia stratiotes (water lettuce) on the removal efficiency of nutrients, organic matter, and selected heavy metals from paint industry wastewater. The experiment was conducted using different biomass quantities of the aquatic plants to evaluate their phytoremediation capabilities. Changes in physicochemical parameters, nutrients, organic pollutants, and selected heavy metals were monitored over a 14-day period. At the end of week 1, water lettuce (WL) achieved removal efficiencies of 37.16%, 62.94%, and 38.47% for NO₃⁻, PO₄³⁻, and NH₃, respectively. Water hyacinth (WH) achieved removal efficiencies of 45.18%, 61.07%, and 45.86% for NO₃⁻, PO₄³⁻, and NH₃, respectively. Similarly, both plants significantly removed heavy metals, with WH achieving average removal efficiencies of 95.91%, 90.88%, and 67.68% for Cr, Pb, and Cu, respectively. WL achieved the highest average removal efficiencies of 90% and 88.9% for Zn and Cu, respectively. A statistically significant difference was observed among the biomass level treatments and heavy metal removal efficiencies (p < 0.05). The results indicate that both species effectively reduced nutrient, organic pollutant, and heavy metal concentrations, with higher biomass levels showing greater removal efficiencies. WH exhibited slightly better performance in removing all evaluated parameters in the wastewater treatment compared to WL. This study highlights the potential of these aquatic plants for phytoremediation applications in wastewater treatment systems. Optimization of biomass levels and operational conditions could enhance removal efficiencies and make the process more sustainable.

The rapid growth of the human population and industrial activities has resulted in considerable environmental degradation. Processes such as industrialization, mining, agriculture, and waste disposal introduce harmful chemicals that contaminate soil, groundwater, and surface waters. Consequently, soil remediation has become a critical priority for many nations, given that soil quality directly affects agriculture and public health. Nanotechnology presents promising solutions to the shortcomings of traditional soil remediation methods by offering innovative materials and mechanisms for the removal or neutralization of contaminants. This review intends to evaluate the use of nanotechnology in soil remediation, emphasizing the nanomaterials employed, their reaction mechanisms, and potential environmental effects. Nanomaterials like nano zero-valent iron, metal oxides, and carbon-based materials have shown effectiveness in immobilizing, degrading, or extracting pollutants from soil and water through processes such as adsorption, photocatalysis, and filtration. However, certain nanomaterials raise concerns about toxicity and bioaccumulation, which may negatively affect ecosystems and human health. Therefore, additional research is needed to confirm the safety, compatibility, and sustainability of these technologies. This review also identifies significant challenges in the implementation of nanotechnologies for soil remediation and examines future directions and recommendations for addressing these challenges.

This study evaluated the effectiveness of a multimedia filtration system using silica sand, zeolite, activated carbon, blood clam shells, and gravel in reducing microplastic levels in mangrove waters. Water samples were collected from the Wonorejo Mangrove Ecotourism in Surabaya, Indonesia, and were treated using two filtration reactors: Reactor 1 with sand media and Reactor 2 with clamshell media. The downward-flow filtration system demonstrated promising results, with Reactor 1 achieving a 54-60% microplastic removal efficiency and Reactor 2 showing superior performance with a 61-65% efficiency. Fiber-type microplastics were most effectively removed, with Reactor 2 achieving a 67% reduction. The findings highlighted the potential of clamshell media in enhancing filtration efficiency and promoting environmental sustainability. While the system offered a viable solution for mitigating microplastic pollution in aquatic environments, challenges such as scalability, cost-effectiveness, and long-term maintenance required further research. Future studies should focus on optimizing filtration media and assessing real-world applicability for broader environmental conservation efforts.

The Relationship between Households Average Formal Education Levels and Sanitation Practices in Mojo, Surabaya, Indonesia Wardhani, Widhowati Kesoema Harmin Sulistiyaning Titah Mas Agus Mardyanto Eddy Setiadi Soedjono Desludging Education Levels Sanitation Septic Tank Urinary Habit This study explored the relationship between households’ average formal education levels and sanitation practices. Although formal education was intended to prepare individuals for personal and professional life situations, local habits and cultural practices could sometimes be more influential than educational background, as evidenced by urinary habits practiced in the country. These habits played a crucial role in determining whether urine was disposed of in the toilet, processed in a septic tank, or directly entered the drainage system when spilled on the bathroom floor. In this study, the definition of sanitation differed from that previously outlined by the Sustainable Development Goals (SDGs). The SDGs defined sanitation based on the percentage of households that used safely managed services, including handwashing facilities. This study, however, focused on excreta disposal, desludging intervals, septic tank types, and urinary habits, such as whether urine was disposed of on the bathroom floor or in the toilet. These factors were chosen for their ability to accurately reflect the actual conditions observed in the study area. A survey was conducted among 100 households, and data were analyzed using Analysis of Variance (ANOVA). The results revealed no relationship between households’ average formal education levels and sanitation practices. This analysis suggested that other factors, such as cultural beliefs and environmental habits, may have influenced sanitation practices.

Chemical Remediation of Pharmaceutical Pollutants in Contaminated Soils: A Review of Oxidation-Based Approaches Jayasekara, Upeksha Gayangani Siganul, Aimie Peace Premarathna, Kadupitige Shashikala Dilrukshi Pharmaceutical pollutants; chemical oxidation; contaminated soil; adsorption; degradation The objective of this study is to develop effective chemical treatment methods to break down stubborn pharmaceutical pollutants in contaminated soil, enhancing its quality and reducing environmental risks. Numerous pharmaceuticals, which are substances used to cure or prevent illnesses in both humans and animals, are classified as pollutants of increasing concern because of their extensive environmental dispersion and their negative effects on populations. This is due to the constant discharge of sludge and effluent from wastewater treatment plants, which happens far more quickly than the removal of pharmaceuticals; they are frequently discovered in soils at considerable concentrations. Conventional wastewater treatment is unable to effectively remove pharmaceuticals from influent streams or biosolids, despite the fact that they are often present at low ambient quantities. Furthermore, through surface runoff and leaching, the application of animal manure to the soil can cause pharmaceuticals to contaminate the soil. Adsorption to soil colloids and degradation through the soil profile are some of the mechanisms that influence the behaviour and fate of pharmaceuticals in soils. The primary factor influencing how much organic matter is absorbed by plant roots is the sorption of pharmaceuticals in soils. This pharmaceutical pollutant in contaminated soil can lead to a negative impact on human and soil health. Therefore, remediation techniques such as chemical oxidation, soil washing, bioremediation, and phytoremediation should be used to reduce the pharmaceutical pollutants in the contaminated soil.

Assessment of Microbial Contaminants and Antibiotic Susceptibility Patterns of Water Tank Samples from Selected Hostels in Ifite-Awka, Nigeria Okafor, Ugochukwu Chukwuma Eze, Chidera Iloduba, Ugochukwu Samuel Nwachineke, Chigozie Emmanuel Bacterial Isolates Microbial Assessment Water Tank Assessment Student Hostels This research assessed the microbial qualities and antibiotic susceptibility of bacterial isolates from water tank samples collected from ten hostels in Ifite-Awka, Nigeria. The samples were cultured on nutrient agar and Sabouraud dextrose agar, and morphological, biochemical, as well as microscopic analyses were carried out. The bacterial isolates included Staphylococcus aureus, Escherichia coli, Salmonella typhi, Bacillus cereus, and Bacillus subtilis. The fungal isolates included Mucor spp., Aspergillus niger, and Penicillium spp. The colonies ranged from 84 to 234 CFU/ml. Across all species, Levofloxacin and Pefloxacin demonstrated the highest activity, indicating broad-spectrum effectiveness. The poorest results were observed with Rifampicin and Gentamicin, as most isolates exhibited complete resistance. The resistance of coliforms such as E. coli and Salmonella typhi to some β-lactams suggested a potential case of antibiotic misuse within the community. Bacillus cereus exhibited the broadest resistance profile. In the fungal analysis, Mucor spp. was the most common (40%), while Aspergillus niger and Penicillium spp. each accounted for 30%. The presence of coliforms in 45% of the samples indicated poor hygiene and placed people’s health in jeopardy. The lack of routine water tank sanitation and consistent bacterial monitoring in the Awka region was particularly concerning given the presence of pathogenic bacteria and toxin-producing fungi. This research highlighted the importance of strict hygiene practices together with efficient cleaning techniques for water tanks in order to reduce microbial contaminants and coliform bacteria.

Optimization of Manufacturing-Remanufacturing Model in Circular Supply Chain Considering Warehouse Capacity Constraints by Using Chinese Pangolin Optimizer Algorithm Utama, Dana Marsetiya Djirimu, Hanum Salsabila EOQ, manufacturing-remanufacturing, warehouse capacity, carbon emissions, Chinese Pangolin Optimizer, circular supply chain This research developed an optimization model within a circular supply chain framework incorporating factors such as carbon emissions, social sustainability, and warehouse capacity limitations. The model adopted a modified Economic Order Quantity (EOQ) approach, with a comprehensive cost assessment that included production cost, remanufacturing cost, storage cost, disposal cost, and penalty cost for emissions, all formulated within a Mixed Integer Nonlinear Programming (MINLP) structure. To address the complex nonlinear problem, the metaheuristic Chinese Pangolin Optimizer (CPO) algorithm was applied, as it effectively balanced solution exploration and exploitation. The simulation results indicated the optimal combination of production lot size, remanufacturing, and the share of reusable goods, achieving the minimum total system cost. The sensitivity analysis showed the significant influence of production and remanufacturing costs, emissions, and the rate of product returns on system efficiency. Overall, this research demonstrated more credible, cost-efficient, and sustainable inventory control approaches in a circular supply chain by considering warehouse constraints and applying the CPO.

Digital Lifestyle and Food Waste Behavior: The Role of Camera Eats First in Cafes and Restaurants in Batam City, Indonesia Saputra, Eryd Alhamdi, Rezki food waste behavior camera eat first emotional attitude perceived behavioral control Camera eat first referred to the habit of photographing food before consumption for sharing on social media. This phenomenon drove shifts in consumer behavior, potentially leading to increased food waste. The objective of this study was to analyze the influence of attitude, emotion, and perceived behavioral control on food waste behavior, with camera eat first included as a mediating variable. A quantitative approach was employed, involving a sample of 340 respondents who were visitors to cafés and restaurants in the Harbour Bay area of Batam. Data were collected using a five-point Likert scale questionnaire and analyzed through Structural Equation Modeling–Partial Least Squares (SEM-PLS) using SmartPLS software, as well as Fuzzy-Set Qualitative Comparative Analysis (fsQCA). The findings revealed that emotions and perceived behavioral control exerted a positive and significant effect on food waste behavior, whereas attitude and camera eat first did not show significant influence. Furthermore, camera eat first was not confirmed as a mediator in the relationships among the studied variables. Complementary results from fsQCA highlighted that the combination of attitude, emotion, and perceived behavioral control constituted the most consistent configuration in explaining food waste behavior. Overall, the study concluded that food waste behavior was more strongly shaped by internal psychological factors than by digital lifestyle trends. Consequently, strategies to reduce food waste should prioritize strengthening self-control, enhancing emotional awareness, and promoting responsible consumption practices, while also accounting for the dynamics of social media engagement in contemporary society.

Occurrence, Risks, and Treatment of Pharmaceutical Contaminants in Malaysia’s Aquatic Systems Kiranparahita, Edita Ayoka Rahman, Nur Afiqah Mwangi, John Pharmaceutical contaminants; Drinking water quality; Hybrid wastewater treatment; Environmental and public health Pharmaceutical and personal care products (PPCPs) are increasingly recognized as emerging contaminants in aquatic ecosystems due to their persistence, bioaccumulation potential, and adverse effects on both human health and aquatic life. In Malaysia, particularly in the state of Selangor, the rapid growth in population and healthcare demand has led to rising pharmaceutical consumption and subsequent contamination of surface water, tap water, and drinking water sources. Recent studies have detected compounds such as diclofenac, triclosan, ciprofloxacin, caffeine, and sulfamethoxazole in local water bodies, with concentrations often exceeding those reported in developed countries such as Australia and Taiwan. This trend highlights the inefficiency of conventional wastewater treatment plants (WWTPs) in removing pharmaceutical residues. The persistence of these contaminants poses potential health risks, including antibiotic resistance, endocrine disruption, and long-term toxicity to aquatic organisms and humans. Current treatment technologies in Malaysia, including adsorption, bioremediation, and activated sludge systems, have shown partial removal efficiency but remain inadequate for complete elimination of PPCPs. To address this limitation, emerging research recommends integrating hybrid treatment systems that combine biological and physicochemical processes to enhance contaminant removal efficiency. The aim of this study is to assess the occurrence and distribution of pharmaceutical contaminants in Selangor’s aquatic system, evaluate their potential risks, and discuss the limitations of existing wastewater treatment technologies while proposing sustainable alternatives for improved water quality management. Overall, the findings emphasize the urgent need for policy revision, technological innovation, and stricter monitoring to safeguard public health and environmental integrity in Malaysia.

Multi-Actor Governance of Waste-to-Energy: A Case Study of the Putri Cempo Waste-to-Energy Power Plant in Surakarta City Rosi, Syavina Damar Sandria, Andriko waste-to-energy global governance power plant SDGs putri cempo This research examined the dynamics of governance in waste management through a case study of the Putri Cempo waste-to-energy (WTE) power plant. The growing volume of global waste has driven the need for multi-level governance to advance WTE technology. The application of WTE technology became part of the national commitment to climate change mitigation outlined in the Nationally Determined Contribution (NDC) framework. The development of WTE also contributed to the attainment of several Sustainable Development Goals (SDGs), notably SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action), by providing renewable energy and reducing greenhouse gas emissions. The main focus was to analyse how multi-actor governance was implemented in WTE management practices at the local level, as well as the challenges that arose in ensuring operational sustainability. Employing a descriptive qualitative approach, this study adopted a multi-actor and institutional governance perspective and applied Biermann’s Five A’s concept, architecture, agency, adaptiveness, accountability, and allocation, as the analytical framework for mapping the governance situation of the Putri Cempo WTE facility. The findings indicated that despite regulatory support, including Presidential Regulation No. 35 of 2018 and Indonesia’s enhanced NDC targets, the implementation of the Putri Cempo WTE still faced technical challenges, particularly high moisture content specifications and inadequate waste sorting, which disrupted the gasification process. In addition, the surrounding community reported environmental problems. Increasing technical capacity, developing an effective waste-sorting system, and ensuring more transparent environmental monitoring by managers and supervisors were needed to support the long-term sustainability of waste-to-energy power plant operations.

Identification of Microplastics in the Upper Cimanuk Watershed and Waste Management Analysis in Garut Regency, Indonesia Salsabila, Afiefah Sunardi Herawati, Titin Cimanuk Watershed Microplastics Plastic Waste Pollution Waste Management The Cimanuk River was a vital component supporting water resources in West Java. However, further downstream, the water quality decreased due to industrial and household waste disposal. Plastic pollution was a serious issue because plastics in water degraded into microplastics, which were harmful to both ecosystems and human health. This study aimed to assess the abundance and characteristics of microplastics in the Upper Cimanuk Watershed and to explore how waste management was implemented in Garut Regency. The water sampling method for microplastic analysis used non-probability sampling with a purposive sampling technique. The waste management analysis was a descriptive study using a qualitative approach. Microplastics were found in the waters of the Upper Cimanuk Watershed, with the highest abundance recorded at Station 8 (2.14 particles/liter) and the lowest at Station 1 (0.62 particles/liter). The microplastics identified were dominated by fragments (52%), black-colored particles (47%), and sizes smaller than 1 mm or small microplastics (97%). These findings reflected a high level of microplastic pollution related to human activities around the river. Waste management in Garut Regency had not met its targets, leading to plastic accumulation that could form microplastics. Improvements in facilities, community participation, and policies were needed to control pollution and protect the environment. The results of this study provided baseline data that could inform stakeholders in the Upper Cimanuk Watershed for effective watershed management planning.

Circular Economy Implementation in Community-Based Plastic Waste Management: A Case Study of Waste Bank Amal Haqiqi Garut, Indonesia: An Analysis of Community-Based Plastic Waste Management for Creating Sustainable Environment Purnamasari, Nurfitriyani Utama, Gemilang Lara Ramadhan, Rizky Circular Economy, Plastic Waste, Material Flow Analysis, Analytical Hierarchy Process Waste banks represented a pivotal form of community-based waste management with the potential to operationalize circular economy principles by integrating social, environmental, economic, and technical dimensions. However, empirical verification through systematic performance measurement was essential to validate their effectiveness. This study aimed to analyze the implementation of a circular economy system in plastic waste management at Bank Sampah Amal Haqiqi, located in Bayongbong, Garut. The research first utilized Material Flow Analysis (MFA) to quantify the flow and transformation of plastic waste. Subsequently, the Analytical Hierarchy Process (AHP) was employed to evaluate management performance based on 11 stakeholder perspectives across four criteria: social, environmental, economic, and technical aspects. The AHP results were validated using a Consistency Ratio (CR) of ≤ 0.10. The MFA revealed a plastic waste recycling rate of 76%, with a residue rate of 3.7%. The AHP weighting identified the social criterion as the highest priority (0.33), followed by the technical criterion (0.30). These findings highlighted that management success was predominantly driven by human factors and operational infrastructure. The implementation of a circular economy at Bank Sampah Amal Haqiqi was significant but remained highly dependent on community engagement and technical support. To ensure sustainability, management strategies should have prioritized strengthening social participation and upgrading technical facilities to further reduce residue levels.

Kebonharjo Village, located in the Menoreh Hills, has faced persistent clean water shortages due to climate variability, environmental degradation, and increasing water demand. These conditions have intensified social vulnerability, especially among women, who are primarily responsible for household water management and water-dependent livelihood activities. This study aims to examine women’s multidimensional vulnerability to drought, analyze wastewater management as a form of local wisdom-based adaptation, and identify policy implications for gender-responsive disaster risk reduction. Using a qualitative case study approach, data were collected through in-depth interviews, focus group discussions, participatory observation, and document analysis from January to March 2025. Data were analyzed using the interactive model of Miles and Huberman. The findings reveal that women experience physical vulnerability due to long distances to water sources, economic vulnerability resulting from declining agricultural income and increasing household expenditures, and structural vulnerability linked to limited participation in village-level decision-making. At the same time, women demonstrate strong adaptive capacity through wastewater reuse, rotational water collection, and ecological knowledge of seasonal indicators. The novelty of this study lies in positioning wastewater management as a gendered adaptation strategy rooted in women’s local wisdom rather than merely a domestic coping practice. The study concludes that integrating women’s local knowledge into village-level drought governance and strengthening their participation in decision-making are essential for building community resilience and advancing gender-equitable disaster risk reduction.

Occupational Health and Safety Risk Analysis Using Hazard Identification, Risk Assessment, and Risk Control Method at Final Waste Disposal Site Suwung, Bali Baskara Andika, Ida Bagus Made Sauqi, Muhammad Zuvisco Widhiawati, Ida Ayu Rai The Suwung Final Waste Processing Site, the largest landfill in Bali, faced major challenges, including overcapacity of waste piles, high fire risks due to methane gas accumulation, and the lack of a structured Occupational Health and Safety (OHS) system. These conditions posed significant hazards that directly affected the safety and health of workers. This study aimed to identify hazards, assess risk levels, and recommend appropriate risk control measures for operational activities at TPA Suwung. This research was conducted at TPA Suwung from March to April 2025, involving 18 workers as respondents. The study focused on four key operational activities: waste truck mobilization, waste reception, landfill structuring, and heavy equipment maintenance. The analysis was carried out using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method to systematically evaluate and manage occupational risks. A total of 30 potential hazards were identified, classified into five categories: physical, mechanical, chemical, biological, and ergonomic. The risk assessment indicated that 3.33% of the risks were low, 36.67% medium, 56.67% high, and 3.33% extreme. The recommended control measures included one elimination, two substitutions, eight engineering controls, twelve administrative controls, and five uses of personal protective equipment (PPE). The findings indicated a high proportion of hazards with significant risk levels, underscoring the urgent need for comprehensive risk mitigation. Effective implementation of the recommended control measures was expected to improve occupational safety and health at TPA Suwung. Strengthening OHS management systems and conducting regular monitoring were crucial to sustaining a safe and healthy work environment.

Implementation of Environmentally Based Citizenship Education in Increasing Waste Management Awareness in Students Saputra, Bherrio Dwi Pratomo, Wachid Kurniawan, Ficky Adi Waste management was a growing environmental challenge that required the development of public awareness from an early age. Schools played a strategic role in fostering such awareness through the learning process, including Civics Education (PKn), which integrated environmental values. This study aimed to analyze the implementation of environment-based civics education in increasing students’ waste management awareness. A systematic literature review was employed by examining relevant scientific articles on civics education, ecological citizenship, environmental education, and waste management published between 2015 and 2025. Data were collected from Google Scholar, ScienceDirect, SpringerLink, and Garuda, and were analyzed using content analysis techniques to identify key concepts, learning approaches, and major findings. The review indicated that environment-based civics education improved students’ waste management awareness by strengthening social responsibility, promoting ecological citizenship, and encouraging practice-based learning such as 5R-based activities (Reduce, Reuse, Recycle, Replace, and Replant). However, its implementation remained constrained by limited curriculum integration, insufficient school facilities, and inadequate teacher competence in integrating environmental values into learning. Therefore, strengthening the integration of environmental education into civics education was essential to develop students’ ecological awareness more effectively.
