Summary: Land application of MSW compost can improve soil fertility and productivity, but there are concerns about its chemical and microbial quality. Current microbial indicators may not accurately represent the presence of more resistant pathogens. This study evaluated the microbial characteristics of MSW compost and estimated health risks associated with exposure to potential pathogens. While recommended standards for fecal coliforms and Salmonella were generally met, detectable levels of microbial pathogens were present. Cryptosporidium posed the highest daily infection risk followed by Salmonella and Campylobacter. Infection risks decreased with time and were low for one-time exposure, but the median annual risk of cryptosporidiosis or gastroenteritis exceeded recommended values. Additional pathogen monitoring may be needed to assess potential risks.

Summary: Composted Organic Fraction of Municipal Solid Waste (OFMSW) is commonly used in agriculture as a source of organic matter and nutrients. In this study, the plastic impurities in the refined compost from five different OFMSW facilities were investigated. The results showed that smaller plants with door-to-door collection systems produced compost with less plastic contamination, while compost from large facilities fed by street bin collection had higher plastic contents. No residual debris from compostable bioplastics was found in any of the samples. These findings suggest that the use of compostable polymers and the implementation of door-to-door collection systems can help reduce plastic impurities in OFMSW compost.

Summary: In recent years, there has been a significant increase in the amount of municipal solid waste, and finding a constructive and economically viable solution is crucial. The use of stabilized municipal solid waste in road construction can help reduce the burden on landfills. By blending SMSW with soil and bottom ash, the organic content can be reduced, and the compaction value, CBR, UCS, durability, and SEM of the blended sample can be tested.

Summary: This study evaluated the compost-like output of Municipal Solid Waste as a potential fuel for Waste-to-Energy practices, and investigated its seasonal variation. The results showed that despite significant seasonal variation, the compost-like output can be used as a sustainable fuel with higher calorific value, lower ash production, lower sulfur oxide content, and lower carbon dioxide emissions. Co-combustion with lignite also showed a synergy effect with lower activation energy.

Summary: This paper investigates the application of municipal solid waste incineration bottom ash (MSW-IBA) in premixed fluid stabilized soil (PFSS), and finds that the NaOH content and activator content have significant effects on the mechanical properties of PFSS. An appropriate amount of NaOH and activator can improve the mechanical strength of PFSS and enhance the microstructure density.

Summary: Sustainable waste management is a crucial issue in modern societies, and scientific research aims to develop effective waste management strategies to address health and environmental concerns. Thermal treatments, particularly gasification, offer viable solutions for municipal waste management. This review critically examines different gasification technologies, feed alternatives, catalysts, and technology adoption. Mixed feedstock management, such as combining municipal solid waste with agricultural waste, can be a practical solution, although economic considerations and waste disposal regulations play important roles in design strategy and implementation.

Summary: Organic solid wastes from onion production in Argentina's rural areas pose management challenges. Research showed significant effects of different doses of compost and compost tea on soil properties, microbial activity, and onion yield, particularly with the highest dose of compost. The study concluded that agroecological onion production with specific compost doses can achieve yields comparable to conventional fertilization.

Summary: Material recovery facilities and mechanical biological treatments are crucial in current municipal solid waste systems, but the composition of their output streams is difficult to predict due to the influence of input stream composition and unit operation sequences. Sorting efficiency and partition coefficients have a significant impact on the recovery potential of these facilities.

Summary: Industrial sludge contains organic matter and plant nutrients that can enhance crop production, but it also increases the entry of toxic heavy metals into the agroecosystem. A field study was conducted to assess the potential of sludge from a soft beverage industry in cereal crops. The study found that sludge application can enhance crop growth and yield, but it also increases heavy metal concentrations in plants. The study suggests that applying lower rates of sludge and nitrogen fertilizer together can minimize the risk of heavy metal contamination while ensuring higher crop yields.
