Municipal Solid Waste Disposal in Hangzhou, China

Abstract

Hangzhou is one of the eight pilot cities for the sorting, collection and disposal of municipal solid waste (MSW) in China. An overview of current status and future plan of MSW disposal in Hangzhou is carried out. The sorting ratio of MSW was estimated to be less than 25% in 2016. It imposes heavy burden on government’s plan of increasing the incineration ratio from 40% to 80% and composting 200 tons of food waste daily in 2020. Through comparison of the landfills, incineration plants and composting plants in Hangzhou, the current standards for the pollution control of MSW disposal facilities are discussed. The risk evaluation during the design period and the monitoring data disclosure during the operation period are suggested to be the mandatory provisions in the future revision of these standards. The work conducted in this paper would provide reference for other cities facing the problem of MSW disposal during the fast urbanization process.
