Abstract

Abstract

With the rapid promotion of waste classification in China, kitchen waste utilization will have a great influence on the energy recovery efficiency of municipal solid waste. Therefore, urban waste treatment infrastructure should be reconsidered. The objective of this work was to measure the moisture contents and heating values of municipal solid waste from 20 communities in Zhangjiagang through field investigation, and predict the changes of moisture contents and heating values of dry waste under different separation rates of kitchen waste. The results showed that based on the existing domestic waste treatment facilities in Zhangjiagang, the separation rate of kitchen waste was not the higher the better. Under the optimized separation rate of 70.8%, zero primary landfill could be realized, and energy recovery efficiency from municipal solid waste could reach the maximum. For the new era of waste classification, the results obtained in this paper was of guiding significance in design of municipal solid waste management scheme for urban administration.
