WRM were commissioned by Grindley Biogas Ltd to secure the environmental permit for the operation of a  biomethane to grid Anaerobic Digestion Plant at Grindley House Farm, Stafford. The site will process 46,000 tpa with a feedstock blend of agricultural slurry and whole crop maize.

WRM advised the client on the most appropriate environmental permit to support the intended site operations. After analysing both current and future capacity provision, as well as targeted feedstocks, the team identified several permitting options and recommended SR2012 No09.

WRM also provided advice on appropriate options to enable the legal operation during the initial seeding and commissioning of the digester.


After agreeing a tight deadline, WRM made the permit application on time and to the high quality expected by the client and the Environmental Agency.

The permit was successfully granted on the 31/08/2016.

WRM have an unrivalled performance in service delivery with a 100% approval success rate.
