Thermal hydrolysis

What is thermal hydrolysis?

Cambi’s thermal hydrolysis processes are at the heart of advanced treatment of sewage sludge and bio-degradable waste, whether planning new or upgrading existing wastewater treatment, food waste or co-digestion projects. Conventional problems are reduced, and the material itself becomes a truly valuable resource. Through Cambi’s well tested processes, material and energy recovery is lifted to a whole new level, while minimizing the amount of end-product & maximizing its quality. The results are reduced operational costs and problems turned into products.



Advanced Anaerobic Digestion, using sludge conditioning processes to speed up and improve the AD process, improve dewatering and quality of digestate


Sludge or biodegradable waste having been processed by Anarobic Digestion


Thermal Hydrolysis (Process), for pressure-cooking of organic material to improve AD


Waste / Surplus activated sludge

Activated Sludge

Common biological treatment process for wastewater


Organic waste materials that are not sewage sludge. Usually referring to food waste from households, restaurants, grocery stores, etc.

Food waste

Food discarded or lost uneaten. The causes of food waste or loss are numerous, and occur at the stages of production, processing, retailing and consumption.
