Advanced thermal treatment technologies utilizing pyrolysis or gasification, as well as a combined
approach, are introduced as sustainable methods to treat wastes in Singapore. Eight different technologies
are evaluated: pyrolysis–gasification of MSW; pyrolysis of MSW; thermal cracking gasification of granulated
MSW; combined pyrolysis, gasification and oxidation of MSW; steam gasification of wood; circulating
fluidized bed (CFB) gasification of organic wastes; gasification of RDF; and the gasification of tyres.
