摘要
随着我国城市矿产开发的大力进行,其各方面的积极效益日益凸显。本文分析了我国城市矿产开发利用现状,并利用IPCC提供的温室气体排放清单计算方法,对2011—2014年我国废钢铁、废纸和废塑料的回收引起的CO_2和CH4减排量进行统计分析。结果表明:2011—2014年我国主要城市矿产开发的再生资源累计回收量为803.275 Mt,其中废钢铁、废纸和废塑料回收量最大,分别占2014年回收总量的62.2%、18.0%和8.2%;2011—2014年废钢铁、废纸和废塑料回收引起的温室气体累计减排量分别为27.962 Mt CO_2-eq,954.695 Mt CO_2-eq和22.502 Mt CO_2-eq,合计1005.159 Mt CO_2-eq,温室气体减排效益明显。
With vigorous implementation of China’s urban symbiosis development, positive effects in various aspects have been increasingly emerging. Firstly, the status quo of China’s urban symbiosis development and utilization was introduced and a statistical analysis of the emission reduction of CO2 and CH4 caused by recovery of iron and steel scraps, waste paper and waste plastics was made in China from 2011 to 2014 using the greenhouse gases (GHG) emission inventory calculation method provided by IPCC. The cumulative recovery of renewable resources during China’s main urban symbiosis development in 2011-2014 was 803.275 Mt, and the recovery of iron and steel scraps, waste paper and waste plastics was the largest, which respectively accounts for 62.2%, 18.0% and 8.2% of the total recovery in 2014. The cumulative emission reduction of GHG caused by recovery of iron and steel scraps, waste paper and waste plastics in 2011-2014 was 27.962 Mt CO2-eq, 954.695 Mt CO2-eq and 22.502 Mt CO2-eq, respectively, totaling 1005.159 Mt CO2-eq, so the GHG emission reduction effect is remarkable.
