Thermal destruction - non-oxidative

Non-oxidative thermochemical treatment of sewage sludge refers to treatment at elevated temperatures in the absence of oxygen. Methods include hydrothermal processes (HTPs), pyrolysis, and gasification, where gasification is based on partial oxidation of the organic carbon. Whereas pyrolysis and gasification require a substantially dry sludge product, HTPs are effective for sludges having a significant water content.

Co-processing of sewage digestate by hydrothermal carbonisation

Hydrothermal carbonisation (HTC) can be used to co-process anaerobic digestion (AD) digestate and lignocellulosic (or plant-based) feedstocks to improve the the hydrochar product quality. This AD waste co-processing route has been studied at bench scale.
