A groundbreaking venture is set to make the best use of leftover curries, by using it to help produce enough gas to supply more than 1,400 homes.
A 5million-pound plant is being built in Britain, which will process food waste from takeaways, curry restaurants, hotels and offices.
The scraps will be heated after being slopped into large containers that work in the same way as a cow's stomach.
Natural bacteria will break down the food to create biomethane, which is similar to the natural gas that is used in homes for central heating and cooking.
The biomethane will be cleaned and fed into the National Grid.
It is Britain's first project built from scratch on the back of the Government's renewable heat incentive, in which firms are paid a premium for "green" gas.
The plant in Stockport, Greater Manchester, which is a joint venture between British Gas and the Bio Group, is on an old landfill site and is expected to be up and running in 2012.
It will be capable of processing roughly 25,000 tonnes of food waste a year - some of the leftovers will come from the canteens at British Gas.
"This project shows how recycling waste that would otherwise go to landfill is not only good for the environment but can also play a vital role in meeting people's everyday energy needs," the Mirror quoted Gearoid Lane, the company's managing director of new markets as saying.
The mulch that is left after the gas is extracted from the food scraps at the plant will be sold to farmers for fertiliser.
