The CEO and co-founder of bio-bean, the 2014 winner of the Postcode Lottery Green Challenge, scooped another award last night, as he was announced as the Guardian Sustainable Business Leader of the Year 2015.

The prestigious award, which is voted for by the public, recognised founder Arthur Kay's innovation in setting up bio-bean Limited, a green energy company that recycles waste coffee grounds into Advanced Biofuels.

bio-bean has long been supported by United Postcode Lotteries, including People's Postcode Lottery, after it won the top prize of €500,000 in the 2014 green entrepreneur competition Postcode Lottery Green Challenge.

At the time of his win last year, Mr Kay said, "This is fantastic! With this prize money, we can scale up production to other locations throughout the UK. We also want to expand internationally. The cash prize will enable us to develop new technologies and products, securing bio-bean's market position."

bio-bean, which operates from a Central London HQ and a 20,000 square-foot factory, create two carbon-neutral fuel products from waste coffee grounds: coffee biomass pellets used for heating buildings and biodiesel used for powering transport systems.

bio-bean's coffee waste collection service operates throughout Central London, servicing hundreds of locations. This integrated service works within existing supply chains to save money and hundreds of tonnes in CO2 emissions for partnering companies.
