Supercritical water oxidation
Supercritical water oxidation (SCWO) refers to the rapid oxidation of organics in water in the supercritical phase of water. 'Supercritical’ refers to the state of water within a specific region of pressure (>218 bar) and temperature (>374 °C) where water becomes both a solvent and oxidant for all chemical species.

Feature
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
