Shell, Bio-bean power London buses with waste coffee grounds

Coffee oil-based biofuel to run London's buses

Coffee oil-based biofuel to run London's buses

The B20 biofuel, which uses a 20 per cent bio-component containing coffee oil, is to be added to the London bus fuel supply chain, the two firms said.

The average Londoner consumes an impressive 2.3 cups of coffee every single day.

London buses will soon transport people around the capital using a fuel partly derived from waste coffee grounds, after Royal Dutch Shell and Bio-bean agreed a deal with Transport for London (TfL).

He adds that bio-bean's coffee logs, which are eco heat logs made from spent coffee grounds to be used for stoves, open fires and chimneys, have already become the fuel of choice for households looking for a high-performance, sustainable way to heat their homes.

The startup collects used coffee grounds from cafes, restaurants and factories, and transports them to its recycling facility. The company then worked with its fuel partner Argent Energy to process this oil into a blended biofuel.

Up to 50,000 tonnes of waste coffee grounds can be recycled in Bio-Bean's factory annually, with the coffee sourced through partnerships with coffee shops and factories across the UK.

Transport for London has been turning to biofuels to curb carbon emissions, trialling a fuel made with used cooking oil from the catering industry, the transport operator said on its website.

Some 6,000 litres of coffee oil have been produced so far, the company said.

Shell supports the trial as part of its #makethefuture energy relay. Founder Arthur Kay tells the Independent that coffee actually has very high oil content - 20 percent by weight - so "it's a really great thing to make biodiesel out of".

Shell Singapore said, "The technology holds much potential for heavily motorised countries". If it were exclusively combined with the mineral diesel that would produce enough fuel to power a London bus every day for a year.
