Cambi signs large THP contract for Ellesmere Port bioresources hub in Cheshire, UK

02 Mar 2026 13:54 CET

Cambi ASA has signed a large contract with J. Murphy and Sons Limited to deliver
two thermal hydrolysis process (THP) systems to the Ellesmere Port bioresources
treatment centre in Cheshire, United Kingdom.

The investment supports United Utilities' AMP8 programme to build centralised
regional treatment hubs and increase renewable energy production, through an
Enterprise delivery model alongside other partners, including J. Murphy and Sons
Limited. THP installation at Ellesmere Port will allow the centre to accept
material from a wider area, with around two-thirds of the planned throughput
expected to come from other sites.

Thermal hydrolysis is expected to raise overall biogas production by about 20%
compared with conventional digestion of the same sludge volume. At Ellesmere
Port, biogas is primarily upgraded for grid injection. Net additional biomethane
is sufficient to heat around 400 homes each year with renewable gas.

Thermal hydrolysis also improves dewatering, reducing biosolids volumes by
around 35%. United Utilities intends to recycle biosolids to land, retaining
long-term flexibility to route biosolids to thermal outlets, such as
incineration, if required.

Per Lillebø, CEO of Cambi, remarked:
"United Utilities is a longstanding and important client for Cambi in the UK.
The Ellesmere Port project forms part of United Utilities' AMP8 bioresources
investment programme, supporting a move to larger, modern hubs in response to
regulatory requirements at digestion sites. We appreciate the trust placed in
Cambi and look forward to collaborating with Murphy on delivery."

United Utilities provides water and wastewater services across north-west
England and operates a large bioresources network serving over seven million
people and thousands of businesses. The company is concentrating sludge
treatment at fewer, modern sites to reduce methane emissions across the network
and support compliance with the Industrial Emissions Directive at anaerobic
digestion facilities.

Ellesmere Port wastewater treatment works is also undergoing modernisation to
accommodate population growth and increased loads, including from industrial
effluent linked to the Stanlow refinery.

Equipment delivery is scheduled for late 2027, with operations starting in 2028.
