Gasification

Gasification is an extension of the pyrolysis process for thermochemical treatment of sludge, with the conversion taking place in a partial reducing atmosphere at higher temperatures than those used for pyrolysis. The process aims to completely convert the carbonaceous content to a solid ash and a clean combustible gas product (called syngas) for use locally.
