Welcome to Attleborough Biogas

About this site.

The Attleborough Biogas Plant in Norfolk is one of the UK’s leading examples of a circular-economy energy model. The facility processes over 100,000 tonnes of food waste every year from local businesses and the surrounding community. In return, the plant produces renewable biomethane equivalent to the annual gas demand of around 4,000 homes and businesses in the town.

Organic waste is received, pre-treated and fed into large, oxygen-free digester tanks, where anaerobic bacteria break the material down and generate biogas. This gas is then upgraded to biomethane for grid injection, allowing Attleborough to operate as one of the UK’s first “green gas communities.”

The new site included digesters, a waste-reception hall and an expanded gas-upgrading system, enabling the plant to reach roughly 10 megawatts per hour of renewable energy output.

What we did.

ConstructionCrew Ltd delivered a wide range of core installation packages across the Attleborough facility, supporting both the site installation and the integration of new process systems. Our work included:

• Full pipework fabrication and installation across feed, heating, recirculation and gas-handling systems.

• Fabrication and installation of the site’s bespoke heating system to maintain stable digester temperatures and support pasteurisation requirements.

• Cladding and insulation of process tanks to provide long term protection, thermal efficiency and compliance with site standards.

• Installation of all digester mixers to ensure consistent substrate blending and improved gas yield.

• Installation of the gas roofs on the digesters, providing safe biogas capture and stable internal operating pressures.

These works formed the backbone of the plant’s digestion, heating and gas-storage systems and supported the integration of the upgrading technology.

Sustainability & Regional Impact.

CCL worked closely with the project developer, technology suppliers and the main EPC contractor throughout the build. Daily coordination with other contractors and teams on site ensured seamless integration between tank infrastructure, process equipment and the plant building.

Clear communication, staged handovers and strict adherence to site health and safety standards kept the project on schedule and fully aligned with the client’s technical requirements.

Partnership & Collaboration.

The Attleborough Biogas Plant transforms local food waste into renewable energy, allowing households and businesses to directly benefit from the material they recycle. By diverting more than 100,000 tonnes of organic waste from landfill each year and converting it into biomethane, the site significantly reduces carbon emissions and improves regional waste sustainability.

CCL’s installation work supports effective digestion, efficient heating, strong gas capture and reliable upgrading performance. The result is a resilient renewable-energy facility that enables Attleborough to lead by example in community-led sustainability and low-carbon energy production.
