What is thermal hydrolysis?

Thermal hydrolysis is a technology that uses heat and high pressure to break down organic materials, such as sewage sludge, biomass, or food waste, supporting anaerobic digestion and enabling more efficient disposal or further processing.

Press play and see how thermal hydrolysis looks in action!

Environmentally compliant, efficient, reliable. For now and forever.

With Cambi, you're not just buying a thermal hydrolysis solution; you're securing a partnership for the lifetime of your plant. We offer technology that is both mature and reliable, explained in terms that you and your clients will easily grasp.

Understand thermal hydrolysis

Higher efficiency, lower operational costs.

Thermal hydrolysis optimizes the digestion process, reducing the volume of organic matter and water left after digestion while increasing biogas production. By boosting digester loading rates, thermal hydrolysis saves funds that would otherwise be spent on expanding current facilities.

A greener way to cost-efficiently manage waste.

More biogas, pathogen and bacteria-free biosolids, lower emissions from transport and processing - thermal hydrolysis not only reduces the environmental footprint of conventional waste processing but also produces valuable resources in the form of energy and soil products. Implementing our solution means taking pride in contributing to a greener, cleaner local environment.

Andy Knowles

Operational Supervisor, Cog Moors WWTP

Cambi has a great gas yield, higher than that of many other companies we examined. Having the Cambi system means that we are now almost a self-sufficient site.

Thorbjørn Netteland

Operating Manager, Hias WWTP

Thirty years with the Cambi process have proven to us that it is a very stable and robust technology. The cooperation with the Cambi team has always been good, and their staff provide valuable advice. Based on our experience, I have no problem recommending the Cambi technology to others.

Trent Crayden

Superintendent, Medina KWH WRF

We reduced our electric bill by over half by switching to advanced digestion using CambiTHP. I recommend the Cambi system because, on top of the economic benefits, you have the ease of operation and maintenance.

Hans Reith

Process Engineer, Hengelo WWTP

In the Netherlands, sludge disposal costs about €100 per tonne, so this [biosolids] reduction has made a big financial impact. We now save €1 million annually just on sludge disposal costs.

Jakub Mukawa

Technologist, Tarnów WWTP

After starting the Cambi THP process, the sludge smell problem just vanished. The quality of the final sludge is much better, and we can now use it for land reclamation without any odour problems. Moreover, we now help other plants with their sludge processing, giving us more energy and extra income.

George S. Hawkins

Former General Manager, DC Water

Cambi provides three major benefits. Firstly, it eliminates risk; secondly it saves significant amounts of money; and finally, it provides very dramatic environmental benefits. Any one of those by itself would be a sufficient driver for the project.

Across the company, we currently generate around 34% of all of the energy we use as a business, and the thermal hydrolysis process will move us closer to our target of making that 50%.

Dŵr Cymru Welsh Water: Strengthening EnergyResilience at Cog Moors with CambiTHP

Cog Moors Wastewater Treatment Works in South Wales is a key asset in Dŵr Cymru Welsh Water’sregional sludge strategy. Facing ageing equipment and limited energy recovery, the utility convertedthe site from conventional digestion to advanced anaerobic digestion with Cambi thermal hydrolysis.

Hias: Pioneering the World’s First Full-Scale THP Plantfor Compliance, Resilience and Sustainability

When Norway introduced strict new sludge regulations in the early 1990s, Hias faced increasing pressure to modernise its sludge treatment process, eliminate odour issues, and ensure long-term compliance. In partnership with Cambi, the utility commissioned the world’s first full-scale thermal hydrolysis process (THP) plant in 1996.

Medina County’s Biosolids Upgrade: Energy Recovery and Exceptional Quality

Faced with increasing operational costs, a failing 40-year-old Zimpro wet air oxidation system (WAO), and rising solids inventory, the utility undertook a major upgrade in 2018. By implementing Cambi’s thermal hydrolysis process (CambiTHP) in combination with anaerobic digestion, the plant radically improved its energy profile, biosolids quality, and long-term sustainability.
