Strategic carbon emission assessment in sludge treatment: A dynamic tool for low-carbon transformation

Environment International, Год журнала: 2024, Номер 193, С. 109124 - 109124

Опубликована: Ноя. 1, 2024

The carbon-neutral target presents a significant challenge for the sewage sludge treatment and disposal (SSTD) industry, necessitating strategic planning low-carbon transition. However, flexible comprehensive carbon emission analysis tools to support this goal remain lacking. This study tool evaluate characteristics future mitigation potentials of SSTD. integrates life cycle inventory (LCI) modeling-based analysis, sensitivity regression scenario analysis. Carbon emissions are dynamically calculated based on properties, technological level, industry external parameters, providing foundation adaptable evaluation tailored local conditions. framework considers potential effects multi-parameter multi-aspect changes in scene design, both within outside achieve dynamic simulations. A case conducted Wuhan, China, demonstrated usability application processes framework. results indicated that from SSTD projected more than double 2021 2060 without interventions. Among measures, energy chemical savings would yield largest reduction potential, followed by technical layout adjustment promotion efficiency. Operational optimization contribute least. With all measures applied, could decrease -82.91 kt CO

Sustainable Sludge Management in China: Quantifying GHG Emissions and Exploring Its Reduction Strategies

Опубликована: Июнь 14, 2024

This study aims to quantify greenhouse gas (GHG) emissions from China's sludge treatment industry and explore the potential of novel technologies mitigate these emissions, promoting sustainable management practices. Using a life cycle assessment approach, total GHG in 2017 were estimated at 18.54 Mt CO2-eq, with significant regional variations. Incineration contributed highest (1,011.53 kg CO2-eq/t dry sludge), followed by landfill (717.51 CO2-eq/t) land application (276.41 CO2-eq/t). The uneven distribution across cities highlights need for targeted mitigation strategies that consider local sustainability challenges. Principal component analysis revealed economic factors scale significantly influence emphasizing importance integrating goals development. To reduce carbon footprint enhance sustainability, costs various evaluated, including thermal conversion, anaerobic digestion, hydrothermal processes, wet oxidation. These offer emission reductions ranging 0.09 0.46 t solids compared conventional methods, while also resource recovery circular economy principles. However, further optimization is necessary their environmental performance, ensuring long-term sustainability. By implementing adopting strategies, can contribute achieving country's neutrality goal fostering
