Construction begins on UK´s largest anaerobic digestion CHP plant

Date: 31 January 2013

Construction is now underway on one of the UK´s largest anaerobic digestion (AD) plants, which is expected to be capable of converting 90,000 tonnes of commercial and domestic food waste into energy


The 4.2MW plant is being built on PDM´s existing rendering and renewable energy generation site on Desoto Road, Widnes, and once completed, will have the capacity to handle 90,000 tonnes of commercial and domestic food waste. 


The 4.2MW plant in Widnes is the second industrial scale plant developed by PDM the opening of a smaller facility in Doncaster in 2011 (pictured). Both plants will be run by the company´s food waste recycling and collection brand, ReFood.


The new £20m plant will have 50 percent more capacity than the Doncaster facility, with three combined heat and power (CHP) engines to convert the biogas produced during the AD process into enough renewable electricity to power 8,000 homes, as well as 4,000kg/hr of steam and hot water.
