Thermochemical processes

Thermochemical methods are employed for either significantly reducing the sludge solids content, or pre-treating sludge upstream of anaerobic digestion (AD) to increase the biodegradability of the organic carbon. When operated at elevated temperatures, i.e. for solids destruction rather than for AD pre-treatment, they provide energy recoverable either as heat (for oxidative processes) or a combustible gas or liquid (non-oxidative processes).

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. Read article
