The major components are plastic (PE and PP), food and kitchen waste, and paper, whereas the minor components are textile, rubber, and biomass. Gasification of biomass yields a number of different products in the solid, liquid and gas phases, the distribution and composition of which depend on the gasification technology applied, in . Gasification converts MSW to a usable synthesis gas, or syngas. Final Rule - January 2, 2008 | Proposed Rule - March 25, 2002 . It is documented that about 80 % of energy embedded in solid wastes can be recovered as heat in steam-turbine (DEFRA, 2013).The LHV waste of the solid waste is determined according to Eq. These systems can be stacked in order to accommodate varying amounts of throughput. Gasification is the referred technique to produce syngas. In the United States, the yield of MSW reached 2.54 108 t in 2013, only 34.3% of which was recycled [3]. Biomass gasification is a mature technology pathway that uses a controlled process involving heat, steam, and oxygen to convert biomass to hydrogen and other products, without combustion. Introduction In recent years, municipal solid waste (MSW) has become a major environmental concern all over the world [1,2]. The gas resulting from waste gasification contains various tars, particulates, halogens, heavy metals and alkaline compounds depending on the fuel composition and the particular gasification process.
