Incineration of sludge
Incineration is the most well established and widely implemented of the sludge thermochemical treatment processes
Oxidative thermochemical treatment
Oxidative thermochemical treatment of sludge
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 byproducts (such as nitrogen oxides or NOx) present at lower concentrations, and a solid residue. The 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.

Anaerobic digestion optimization through thermal hydrolysis pre-treatment
Pre-treatment of sludge by thermal hydrolysis upstream of anaerobic digestion is used to improve AD efficiency. A study looked at (pre-)commissioning data for a full-scale AD installation undergoing upgrading with TH to assess the basis for optimisation.
