Waste coffee grounds will be used to help power some of London's buses from Monday, it has been revealed.
A biofuel created by blending oil extracted from coffee waste with diesel is to be added to the public transport fuel supply.
Technology firm bio‑bean says it has produced enough coffee oil to power one bus for a year.
Transport for London has increasingly turned to using biofuels to reduce transport emissions.
However, this is thought to be the first time a coffee‑derived biofuel has been added to London's public transport system.
