The SARIA Group’s UK Doncaster site is now running completely off-grid and using 100% renewable energy, thanks to its ReFood anaerobic digestion (AD) plant, the company said on 3 August.

SARIA is Europe’s largest food by-products processor and manufactures products for use in human and animal foodstuffs, agriculture, aquaculture and industrial applications, as well as bioenergy in the form of fats, biodiesel and biogas. It also offers collection and disposal services for biological and plant waste including waste oils.

The Doncaster site recycles more than 160,000 tonnes of food waste every year, and generates 5MWh of electricity via combined heat and power (CHP), alongside hot water and heat. A sustainable biofertiliser is also produced as a by-product of the process, which is used by local farmers.

Part of the energy produced is now being used to power other businesses sharing the Doncaster site including Nortech Foods, which produces a range of animal and vegetable fats for catering and consumer use; the SARVAL pet food plant; and SPF and APC GB, which supply ingredients for use in pet food products.

SARIA Ltd, formerly Prosper De Mulder, became a wholly-owned subsidiary of the SARIA Group on 29 February, when shareholders agreed to the group’s acquisition of a further 49% of shares in the UK business.
