Proving the concept of sewage sludge pyrolysis
Amount awarded: £6,205,773
Led by: Thames Water
Partners: Cranfield University, Helsinki Region Environmental Services (HSY), Southern Water, Stantec Ltd, Uisce Éireann, Yorkshire Water
Further details on Proving the concept of sewage sludge pyrolysis are available on the Thames Water website.
We aim to deliver the first continuously operating, sludge-fed UK-based pyrolysis demonstration plant. Pyrolysis (a high temperature process with no oxygen present) can be used to recycle sludge to maximise the value of biosolids; ensuring a circular economy and reducing the requirement for sludge to be recycled to agricultural land.
“Sludge is a resource not a waste, it contains nutrients required for plants and usable energy. This investment opens the door for a circular economy approach and can contribute to net zero carbon, enhance the environment and add operational resilience, therefore providing a sustainable future for biosolids management.” – Nevil Muncaster, Engineering & Asset Director, Thames Water

Update from the project (April 2025)
The project is currently in the procurement phase, as we seek an appropriate OEM and delivery partner to supply, install, and commission the pyrolysis pilot plant. Together, we’re setting a new standard for resource recovery and driving innovation across the water industry.
