Abstract

Rapid urbanization exacerbates the contradiction between energy recovery from Municipal Solid Waste (MSW) and climate change mitigation under regional resource misdistribution. This study establish a high-precision MSW incineration treatment carbon emission accounting inventory based on the activity data of 166 cities and 324 incineration power plants in four major urban agglomerations in China. Based on the identified key drivers affecting the spatial differentiation of Carbon Emission Efficiency (CEE) of municipal solid Waste-to-energy (WTE), we discussed the long-term environmental impacts of energy recovery on integrated regional comprehensive management. The results indicate the share of carbon emissions from WTE increased from 16.18 % to 63.67 %, and the carbon reduction potential from energy substitution increased from 1.19 Mt to 16.63 Mt. The carbon reduction rate of the policy scenario that focuses on energy recovery efficiency is optimal. This study provides a sustainable vision and scientific policy recommendations for promoting integrated regional waste management.

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
