**4.3 Gasification**

Gasification is a mature technology and a thermochemical conversion of biomaterials in limited oxygen at high temperature (800-1600°C [39, 40]. It produces syngas that can be burnt to produce heat or used as the source of chemicals. The major constituents of syngas are carbon monoxide which poses a lot safety challenges in its handling. It requires high knowledge and thus is not appropriate for household. It is appropriate to Africa when dealing with lignocellulosic and fine biowaste although inappropriate to MSW due to high moisture content. It is appropriate to every part in Africa although due to low investment, sub-Saharan countries may not effectively fit.
