London city buses will soon run on coffee-derived biodiesel

  • 7 years ago
LONDON — Waste coffee grounds will be powering London's buses, as the city finds newer and cleaner ways to run its public transport system.

BBC reports that clean technology company Bio-bean has created a new biofuel by blending oil extracted from used coffee grounds with B20 biodiesel.

The firm estimates that it would take just 2.55 million cups of coffee to create enough of the biofuel to power a London bus for an entire year.

Bio-bean is working with Shell and Transport for London for its pilot project, which will see about 6,000 liters of coffee oil being used by some buses starting Monday.

Many of the city's buses are already running on biofuel made from wastes such as cooking oil or beef to reduce emissions, but this is the first time a coffee-derived fuel is being introduced.

Londoners reportedly produce about 200,000 tonnes of coffee waste a year, and most end up in landfills where they emit harmful methane gas. The new initiative is not only beneficial to the environment, but also convenient for buses, which don't need to be modified to use the fuel.
