Summary: The increase in population growth has led to an increase in wastewater, waste, and leachate production, causing environmental harm and significant costs. This study estimates the cost of environmental degradation related to these factors in Mohammedia, Morocco, using World Bank methods. Unlike previous studies, this study focuses on a specific city and provides a more detailed analysis. The estimated total cost is around 11.04 million euros, with 3.9 million euros attributed to urban wastewater discharge and 7.1 million euros to household waste and leachate degradation. It is crucial to monitor the cost of environmental degradation to measure sustainable development planning and evaluate environmental policies.

Summary: The USA, China, and India are the top producers of municipal solid waste, with waste composition varying based on income levels. Municipal solid waste management options include recycling, incineration, waste-to-energy conversion, composting, or landfilling. Landfilling is a preferred method globally, with critical factors for sustainability including liners, soil cover thickness, leachate collection, and gas recovery facilities. Landfills act as ecological reactors undergoing various transformations, with bioreactor landfills emerging as a next-generation solution for efficient waste stabilization through controlled recirculation.

Summary: This study investigated the abiotic decomposition of simulated Municipal Solid Waste (MSW) and its impact on landfill gas components. The results showed that the gas composition and temperature were influenced by the heating rate and time. Higher heating rates led to a decrease in the CH4/CO2 ratio, and the release of hydrogen was directly proportional to the amount of CH4 available in the system.

Summary: A large amount of municipal solid waste is being produced due to urbanization, posing serious threats to the environment and human health. The preparation of MSW-derived biochar is an effective strategy for waste reclamation, particularly in wastewater purification through adsorption and catalysis. Classified biochar from MSW, such as food waste and waste paper, has larger surface area and porosity compared to mixed MSW-derived biochar, and various methods of pre-treatment and post-treatment can improve its structure and composition to enhance adsorption capacity and catalytic activity.

Summary: In this study, solid waste plastic was converted into activated carbon fibres through carbonization and chemical activation. The produced activated carbon materials were characterized in terms of morphological structure, composition, thermal stability, and pore structure. The study found that the activation process significantly increased the specific surface area of the carbon materials, making them effective in removing thymol blue dye through adsorption. The study also provided insights into the adsorption isotherm and kinetic measurements of dye removal, as well as the regeneration and reusability of the activated carbon.

Summary: The study showed that early addition of liquid waste did not stimulate anaerobic decomposition of fresh MSW, and most liquid wastes were not suitable as the sole moisture source for bioreactor landfills. MSW reactors co-disposed with sludge produced more methane, while reactors co-disposed with gypsum board or foundry waste also generated methane, despite inhibitory effects indicated by biochemical methane potential (BMP) results.

Summary: Studies on landfill leachate degradation dynamics have shown that the microbial community profile is a valuable tool for monitoring landfills. However, little is known about the changes in the microbial profile during the leachate attenuation process. This study conducted an exploratory analysis of the microbial community profile in a municipal solid waste leachate treatment system in Brazil, and found that each treatment unit had a specific microbial consortium that adapted to changes in leachate characteristics. The structure of the microbial community was found to be sensitive to leachate composition and could be applied to study solid waste management systems.

Summary: This research study investigates the coagulation-flocculation process followed by biological treatment. Two landfill simulated reactors were used to simulate different operation modes, and the removal efficiency of COD in the anaerobic filter was examined. The results indicate that there was no significant COD removal in the anaerobic filter through conventional methods. It is recommended to provide a microbial source for biomass growth to improve the efficiency of the anaerobic filter.

Summary: Sustainable food waste management is crucial for improving food security and conserving natural resources and ecosystems. Diverting food waste from solid waste to wastewater stream allows for separation, collection, treatment, and disposal, while also recovering water, resources, and energy. Extensive studies have been conducted to evaluate the feasibility and impacts of food waste diversion on solid waste and wastewater systems. The review identifies challenges and discusses the contribution of food waste diversion to urban sustainability.

Summary: This study compared the life-cycle impacts associated with various management alternatives for recovering energy and nutrients from the organic fraction of municipal solid waste. It found that mass burn waste-to-energy and gasification scenarios generally have the lowest environmental impacts, while landfilling and gasification Fischer-Tropsch have the greatest impacts. Sensitivity analyses suggest that these conclusions are generally robust to uncertainty in input values.

Summary: Water-energy nexus is a hot topic nowadays, especially the energy consumption in wastewater treatment plants (WWTPs). This study presents a process-level analysis to investigate the feasibility of integrating wastewater and municipal solid waste (MSW) treatment to achieve self-sustainable operation of WWTP. The influence of climate on energy requirements in different regions of the Iberian Peninsula is also evaluated. The results show that integrating these two treatments is technically and economically feasible for a fully self-sufficient and sustainable process.

Response surface methodology was used to evaluate the effect of process parameters on oxytetracycline removal efficiency, showing significant results for both processes. The predicted oxytetracycline removal efficiencies for the PDS and PMS processes were 89.7% and 84.0%, respectively, with the PDS process having higher kinetic constants at all pH values than the PMS process.

Summary: The treatment of paint manufacturing industry wastewater using the electrooxidation process with the addition of peroxymonosulfate and transition metals was investigated. Different anode materials were tested, and the one with the highest removal efficiency of chemical oxygen demand (COD) and true color was selected. Fe2+ was chosen as the catalyst for its higher removal efficiency and lower cost. The process variables were optimized using the central composite design, and under the optimum conditions, high removal efficiencies were achieved. Quenching experiments confirmed the involvement of hydroxyl and sulfate radicals in the process.

Summary: Metal plating industry wastewater is highly toxic due to the presence of heavy metals and cyanide. Conventional chemical treatment methods are commonly used, but they result in the generation of hazardous sludge. In this study, a pilot scale electrocoagulation (EC) process was developed as an alternative. The effect of pH adjustment on the removal efficiency of the EC process was investigated, and significant removals of problematic heavy metals such as copper and nickel were achieved.

Summary: The study analyzed five different methods for waste separation at source, based on the analytical hierarchy process. A model based on residence density was developed to optimize routes for waste management. The results showed that carbon dioxide emissions would only increase by 1.15% compared to the current situation, but the total amount would decrease in the long term if zero-waste management is implemented.
