Abstract:

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.

Key words: urban symbiosis, recovery of renewable resources, GHG emission reduction
