The plant converts food waste into renewable electricity and a co-product called digestate, otherwise known as certified biofertiliser.

The plant, which will turn 11,000 tonnes of food waste per year into green electricity for has been developed under the Wales Procurement Programme, set up by the Welsh Government.

BCS certification is in compliance with the PAS 110 specification and the AD Quality Protocol.

The GwyriAD plant is the 18th AD plant in the UK to achieve BCS certification.
