我国工业减废降碳协同增效路径探索——以食品制造业为例
Exploring the synergistic path of waste reduction and carbon emission reduction in China's industry-taking food manufacturing industry as example
摘要
Abstract
Synergy in the reduction of pollution and carbon is an inevitable choice to promote the construction of a beautiful China and realize China's double carbon targets.The prevention and control of solid waste pollution is one of the important pathways to achieve synergy in the reduction of pollution and carbon.However,synergy pathway in the reduction of waste and carbon is still in exploratory due to the limitation understanding and recognition.This study taked the food manufacturing industry as example to explore the synergy pathway in the reduction of waste and carbon in industry based on the Strengths,Weaknesses,Opportunities and Threats(SWOT)analysis.Meanwhile,this study also assessed the life-cycle carbon emission of food manufacturing industry and 10 sub-industries.Results indicated that total carbon emission and intensity of the food manufacturing industry in Shenzhen decreased significantly from 2012 to 2020.Life-cycle carbon emission of 10 sub-industries varied from 0.19 to 10.86 tCO2e per ton product.The pastry and bread manufacturing sub-industry hold the highest carbon emission while the preserves manufacturing sub-industry were the lowest.Additionally,based on SWOT analysis,synergy in the reduction of waste and carbon for the food manufacturing industry could be achieved through recycle resources and supply chains optimization.However,the weaknesses were supply chains dispersion,enterprises with low enthusiasm and plant-based protein technology imperfect.In future,with the development of China's double carbon targets and"Zero-Waste cities"construction,multiple measures should be taken to achieve synergy in the reduction of waste and carbon,such as completing top-level design,building policy system,promoting green and low-carbon transformation of key technologies.关键词
