The scope of optimization can include a whole range of aspects and possible technological options for conversion and management of sewage sludge, such as:
- processes aimed at improving efficiency of biogas production (e.g. disintegration and hydrolysis processes),
- processes of anaerobic stabilization (digestion) of sludge,
- processes of sludge mechanical dewatering,
- processes of municipal sewage sludge drying (conventional, solar and mixed drying plants),
- processes of thermal treatment of municipal sewage sludge (ITPOs).
