Waste coffee grounds collected from cafes in London are to be used to heat thousands of homes.

The capital-wide scheme will see biofuel company bio-bean turn coffee waste into biomass pellets.

It comes as the firm won the Low Carbon Entrepreneur Award in 2012.

bio-bean’s factory has the capacity to process 50,000 tonnes of waste coffee grounds every year – the equivalent of one in every 10 cups of coffee drunk in the UK.

At full capacity, they can be turned into power to heat the equivalent of more than 15,000 homes. That can help save the equivalent of up to 6.8 tonnes of carbon emissions.

Mayor of London Boris Johnson said: “The roaring success of previous winners like bio-bean demonstrates the huge market for green technology ideas. They’ve done the hard grind and Londoners can now enjoy their daily coffee fix in the safe knowledge that as well as their own caffeine kick the energy levels of as many as 15,000 homes are being boosted!”

The 2016 Low Carbon Entrepreneur Award, with a prize of £20,000, has also been launched.

Earlier this year, Bio-bean secured a deal with Network Rail to collect coffee waste from seven train stations in London.

Another London-based company Beanergi also uses coffee waste from shops and restaurants to generate renewable energy.
