Full of beans: coffee grounds to help power London's buses
(Reuters) - Waste coffee grounds will be used to help fuel some of
London's buses, Royal Dutch Shell (RDSa.L) and clean technology company
bio-bean said on Monday.
A new biofuel, which contains part coffee oil, is being added to the
London bus fuel supply chain where it can be used without the need for
modification, the companies said in a statement.
Bio-bean and partner Argent Energy have so far produced enough coffee oil
to power one bus for a year, if used as a pure-blend for the 20 percent
bio component and mixed with mineral diesel to form a B20 fuel, they
said.
Transport for London has been turning to biofuels to curb carbon
emissions, trailing a fuel made with used cooking oil from the catering
industry, the transport operator said on its website.
Bio-bean said the average Londoner drinks 2.3 cups of coffee a day,
producing over 200,000 tonnes of waste a year. It collects waste grounds
from high street chains and factories, which are dried and processed to
extract coffee oil.
"It's a great example of what can be done when we start to reimagine
waste as an untapped resource," bio-bean founder Arthur Kay said.
The coffee fuel technology has been supported by Shell.
