New biogas CHP plant set to majorly reduce CO2 emissions

A new 520kWe biogas-fired CHP energy plant is set to save an estimated 1,750 tonnes of CO2 emissions each year.

The plant, which will be based in Gloucester for Rose Hill Recycling, will use the biogas derived from mixed food waste collected from across the Cotswolds, with resource management firm Veolia set to increase its capacity for generating renewable energy from food waste by designing and managing the plant.

Composting and recycling facility Rose Hill Recycling processes 35,000 tonnes of food and farm waste per year, while the new CHP site will enable the company to generate 4.56GWh of renewable electricity annually, which is enough to supply around 1400 homes.

The plant is also set to contribute to the Government’s target for 20 per cent of the UK’s power to come from renewables by 2020, while adding to Veolia’s existing 40MWe UK biogas electricity generating capacity.

Gavin Graveson, Veolia’s COO Public and Commercial, believes that although reducing food waste is very important, unavoidable and inedible food waste still has a value as a resource.

“Current estimates show that if all the UK's inedible domestic food waste was processed by AD, it could generate enough electricity for 350,000 households. By effectively optimising all the opportunities for biogas CHP we will ensure we can capture this valuable resource and contribute even more to the circular economy,” he said.

“This latest project effectively moves nearer this goal and has already saved over 1300 tonnes of emissions.”

The site’s anaerobic digestion facility will use the heat from the CHP to help turn the food-waste, animal waste and energy crops into biogas. This is then fed back to the cogeneration unit to provide renewable electricity and heat forming a closed loop energy solution, taking the power demand off the local Grid.

Mark Bennion, Owner and Director of Rosehill Recycling, added: "Food waste sent to landfill gives off methane which is around 20 times more harmful to the environment than CO2.

“By using these scraps and peelings as a renewable energy resource, rather than sending it to landfill, we can help reduce carbon emissions and save local taxpayers money by recycling. It’s a win-win solution that will help to protect our environment.”
