This paper makes a brief introduction to the characteristics of municipal solid waste and methods of energy recovery, proposing that gasification of waste is a new technique for its treatment, which does not cause atmospheric pollution and works at high efficiency. The combination of gasification and melting has several outstanding advantages, such as strict pollution control, noticeable volume reduction and effective resource utilization, and it has attracted attention as the most potential substitution for municipal solid waste incineration. In this paper, the basic theory and process of municipal solid waste gasification and its developing status have been summarized. The advantages and disadvantages of the existing technology are analyzed. Typical gasification process according to the methods gasification-incineration and gasification-melting are introduced and analyzed. And finally, some useful exploration of the domestic application of waste gasification technology is made.
