Hydrothermal gasification

Hydrothermal gasification represents the highest-temperature hydrothermal process, operating at temperatures of up to ~550 °C, producing a gaseous product rich in hydrogen and/or methane. The process is sometimes referred to as supercritical water gasification, since temperatures exceed the critical point for water, and is thus analogous to supercritical water oxidation which operates in the same supercritical region but employs higher temperatures due to the exothermic nature of the oxidation reactions.

Pretty intense: the intensification of sewage sludge processes

Sludge intensification processes increase the sewage sludge solids concentration through thickening/dewatering or the biogas generation by digestion. But at what point do you stop extracting more water from the sludge or enhancing biogas production?
