Coffee to help power London buses starting Monday

Coffee to help power London buses starting Monday

The buses can use the coffee power just like regular fuel without any modification.

Biofuels produced from cooking oil and tallow from meat processing already powers some of London's 9,500 buses, according to the BBC.

To push for its green initiatives, the city of London has increasingly turned to biofuels for its public transportation.

Technology firm bio-bean says it has produced enough coffee oil to power one bus for a year. Biofuel made using waste products such as cooking oil and tallow from meat processing is already used in numerous capital's 9,500 buses, the report said.

The average Londoner drinks 2.3 cups of coffee a day, producing over 200,000 tonnes3 of waste a year, much of which would otherwise end in landfill with the potential to emit 126million kg of CO24.

Bosses claim it would take 2.55million cups of coffee to create enough biofuel to run a London bus for a year - and around 55million cups are drunk in the United Kingdom every day.

The company collects waste coffee grounds mostly from London's coffee shops for processing, and tops the resulting coffee oil with a range of animal and vegetable oil. It will produce 6,000 litres a year of the fuel.

This is then processed into a blended B20 biofuel.

The advantage of using B20 biofuel is that no London bus will need to be modified to use the fuel.

"It's got a high oil content, 20% oil by weight in the waste coffee grounds, so it's a really great thing to make biodiesel out of", said Arthur Kay, founder of Bio-bean, in a phone interview.
