Thermal destruction - oxidative

Oxidative methods for sludge thermochemical treatment comprise incineration, wet air oxidation (WAO) and supercritical water oxidation (SCWO). These processes convert the combustible organic matter to primarily carbon dioxide and water, along with other gaseous oxidised products present at lower concentrations, and a solid residue. These methods differ in terms of the operational temperature and pressure, the required feed sludge water content, and the nature and concentrations of gaseous and solid products generated.

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.
