The challenge

COOK has expanded from a small shop in Farnham to 105 locations nationwide, becoming one of the UK’s first certified B Corps through rigorous assessment of their social and environmental impact. However, they sought to reduce reliance on grid-sourced green gas, enhance circularity, and lower waste treatment costs—enter WASE.

Our impact

We installed our miniWASE reactor at COOK’s pudding site in Ilton, enabling them to convert leftover pudding waste on-site, which would otherwise be transported by tankers to an external Anaerobic Digestion plant.

The system was set-up quickly and started generating gas very quickly too. This is a really good example of the circularity and sustainability we are looking to achieve at COOK. The next steps for us now are to start working on the larger installation opportunity at our principle production site in Sittingbourne, where we should be able to unlock considerable carbon reductions and cost savings.

Hepworth Brewery – Wastewater to energy

We are helping the brewery treat their wastewater on the premises, turning it into biogas on-site and avoiding costly collection and disposal.

Llefrith Henfaes Dairy Farm – Slurry waste management

We treat cattle slurry for compliance, generating renewable energy to power the farm and create new revenue streams.
