摘要

快速城市化加剧了区域资源错配下城市生活垃圾能源回收与减缓气候变化之间的矛盾。本研究基于中国四大城市群166个城市和324家焚烧发电厂的活动数据,建立了高精度的城市生活垃圾焚烧处理碳排放核算清单。基于确定的影响城市生活垃圾能源转化碳排放效率空间分异的关键驱动因素,探讨了城市生活垃圾能源回收对区域综合治理的长期环境影响。结果表明,WTE碳排放占比从16.18%增加到63.67%,能源替代碳减排潜力从119 Mt增加到1663 Mt,以能源回收效率为重点的政策情景的碳减排率最优。本研究为促进区域废物综合管理提供了可持续发展的愿景和科学的政策建议。

Carbon emission reduction potential of municipal solid Waste-to-energy under resource mismatch patterns: Evidence from urban agglomerations in China
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.
