Owned by ReFood, the facility is now capable of processing 160,000 tonnes of food waste from across the Yorkshire and Humberside region each year and generating just under 5 MW of electricity via a combined heat and power (CHP) unit.
Alongside two new 3700-tonne capacity digesters, the £6 million ($10 million) expansion work has seen additional receiving and storage tanks added to the site on Ings Road, alongside two 1.1 MW gas engines.
Philip Simpson, commercial director at ReFood, commented: ‘Alongside generating renewable energy, even the resulting digestate (created during the AD process) can be repurposed. In the case of ReFood Doncaster, this is used by a network of local farmers as a PAS 110 certified fertiliser to aid the growth of crops. Known as ReGrow, the industry-first sustainable biofertiliser not only replaces the use of chemicals, but also completely closes the food chain – from field to fork and back again.’
