摘要
在“双碳”背景下,中国城市生活垃圾处理面临低碳减排的新挑战。作者依据贵阳市2006~2020年城市生活垃圾清运数据,运用多元线性回归分析方法对贵阳市2021~2025年城市生活垃圾产生量进行预测。结果表明:贵阳市城市生活垃圾清运量在未来几年仍然缓慢增长。同时,使用《中国产品全生命周期温室气体排放系数集(2022)》估算了2020年贵阳市生活垃圾分类处理碳排放约为58.93万tCO_(2)当量,结合贵阳市生活垃圾处理规划和预测,随着生活垃圾资源化利用水平提高后,2025年贵阳市生活垃圾处理碳排放约-26.49万tCO_(2)当量,实现85.42万tCO_(2)当量的减排,碳减排潜力巨大。
In the background of“Double carbon”,China's Municipal Solid Waste(MSW)treatment faces the new challenges of low-carbon emission reduction.On the basis of Guiyang city MSW output data from 2006 to 2020,we used multiple regression analysis method to forecast MSW output from 2021 to 2025.The results showed that in the next few years MSW output of Guiyang would continue to grow slowly.At the same time,the carbon emission from classifified treatment of domestic waste in Guiyang in 2020 is estimated to be about 589300 tons of CO_(2) equivalent by using the set of greenhouse gas emission coefficients for the whole life cycle of Chinese products(2022).Combined with the waste treatment planning and prediction of Guiyang city,with the improvement of MSW resource utilization level,the carbon emission from classifified treatment of domestic waste in Guiyang will be about-264900 tons of CO_(2) equivalent in 2025,achieving emission reductions of 854200 tons of CO_(2) equivalent respectively,with great potential for carbon emission reduction.
