The Grays Group, based on Anglesey in north Wales, brings together agriculture and energy production from waste activities. Ten years ago the Davis family bought Grays Skip & Plant Hire as a stepping stone into the waste industry, always with an eye on waste as a future resource and energy source. Grays Agricultural will now provide the main feedstock for the Grays Biogas anaerobic digestion plant, which will in turn be managed by Grays Contracting.
