Gasification and Liquefaction Alternatives to Incineration in Japan
Definition of the Subject and Its Importance
The major technologies used in Japan for energy recovery from municipal solid waste (MSW) are mass burning incinerators combined with landfilling of ash. However, shortage of landfill space along with new regulations for dioxin emission control and the Japanese Containers and Packaging Recycling Law has stimulated active R&D and commercialization of relatively novel thermal treatment processes based on gasification and liquefaction of MSW.
The purpose of this article is to introduce novel gasification and liquefaction processes for MSW that are already commercialized in Japan and are potential future alternatives to mass burning for effective resource recovery from MSW.
In Japan, about 40 million tons of municipal solid wastes (MSW) are incinerated each year. Of these, about 20 million tons are used for power generation and in total about 1,000 MW of electric power is produced from MSW. Most of these waste-to-energy (WTE) plants...
