Sludge treatment − pyrolysis
Pyrolysis refers to the decomposition of organic matter at elevated temperatures in the absence of oxygen and water
Non-oxidative thermochemical treatment
Pyrolysis − an example of a non-oxidative thermochemical treatment
Non-oxidative thermochemical treatment methods include pyrolysis, gasification and hydrothermal processes such as hydrothermal carbonisation (HTC), liquefaction (HTL), and gasification (HTG).
An example of the pyrolysis process for sewage sludge is the Eisenmann Pyrobuster® − demonstrating thermal treatment of sewage sludge.

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
