   “Hence, this study scrutinizes the environmental burdens of the composting plant operation from cradle to gate. Because 50% of raw MSW was not converted to compost, its final disposal was evaluated based on incineration, landfill, and integrated approaches. The results indicated marine and freshwater ecotoxicity of the composting process (>50.4 kg 1,4-DB eq). Heavy metal and gas emissions during the MSW decomposition were the pivotal parameters for most impact categories. Carbon dioxide emission intensified climate change by 3,523 kg CO2 eq; however, waste incineration led to emission savings of 98.75%. The environmental benefits of incineration were observed in 13 impact categories alongside a net-negative value for natural land transformation. Landfilling also induced savings in freshwater eutrophication and metal depletion by 98.67% and 99.08%, respectively. Unlike previous studies relying on generalized data, this study uses detailed plant-level operational data and scenario-based modeling from Sistan and Baluchistan province. This approach provides realistic impact estimates and decision-relevant insights.”

   “Scenario 2 replaces landfilling and composting with incineration and anaerobic digestion, respectively. Scenario 3 is the same as Scenario 1 in terms of MSWM pathways except forreasing material recovery rates in line with extended producer responsibility (EPR) targets, thereby reducing the fraction of waste sent to landfill.The functional unit is set to management of 1 ton of municipal solid waste in the Region of Waterloo. Results show clear differences in environmental performance across the scenarios. Scenario 2, which uses incineration for residuals, has the highest environmental impact, particularly in terms of global warming potential over a 100-year time horizon (GWP100), fine particulate matter (PM2.5), and eutrophication. In contrast, scenario 3, which introduces increased recycling rates in response to the region's EPR targets, performs the best overall, achieving substantial environmental savings; 134% reduction in GWP100 and 95% in photochemical ozone formation compared to the business-as-usual scenario. Overall, the findings emphasize how strategic choices in MSWM system design can lead to substantial environmental benefits or burdens.”

   “At the system level, landfill diversion emerges as the most effective mitigation strategy, with additional reductions associated with increased plastic recovery and OV. The current MSW management system exhibits a GWP of approximately 261 kg CO2-eq/t MSW. The lowest GWP (140 kg CO2-eq/t MSW) is achieved in a scenario prioritizing plastic recovery and OV, while meeting the PRR target. Plastic recovery reduces fossil CO2 emissions from WtE but also decreases the energy content of the incineration feed, potentially limiting energy recovery and highlighting a trade-off between recycling performance and operational efficiency in WtE-dependent systems. All valorization processes remain net positive in emissions, partly due to RF sent to landfill or incineration, underscoring the need to reduce contamination and improve processes efficiencies. Overall, the results emphasize the need for integrated MSW management strategies that balance material recovery, energy recovery, and operational feasibility to support effective climate mitigation.”

   “Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms. Waste management practices are not the same across countries (developed and developing nations); regions (urban and rural areas) and residential and industrial sectors can all take different approaches. Effective waste management can be relatively expensive, with one report estimating that it usually comprises 20%–50% of municipal budgets. In high-income countries, waste management typically includes street collection and transportation to controlled or sanitary landfills, incinerators, or recycling centers. In lower-income countries, practices vary, but a sizable portion of waste is stored in open dumps or openly burned, in addition to more sanitary methods.”

   Environmental impacts and sustainability assessment of municipal solid waste treatment: incineration combined with anaerobic digestion/black soldier fly larvae.

   “The global warming potential (GWP) was primarily attributed to direct process emissions from incineration, while AD-INC and BSFL-INC systems yielded net environmental benefits across multiple non-GWP impact categories and demonstrated superior economic performance. The enhanced sustainability is largely attributable to improved resource recovery efficiency, particularly via electricity generation and the production of protein feed and organic fertilizer in the case of BSFL-INC. The sensitivity analysis further revealed that a higher proportion of food waste significantly amplified GWP-related environmental benefits within integrated processes. Under projected decarbonization trajectories of the regional electricity grid, both AD-INC and BSFL-INC systems might maintain the environmental and economic advantages through 2060, highlighting their long-term viability in the context of energy transition. These findings suggest that the integration of biological treatment (AD or BSFL) with incineration offers a promising strategy for reducing environmental burdens and maximizing resource recovery in densely populated megacities.”
