London Is Fueling Their Buses With Used Coffee Grounds

By Brian Spaen

The garbage we throw away continues to give us renewable fuel. New York is turning compostable garbage into biogas that can be used in a natural gas pipeline. In a different part of the world, London is fueling public transportation from used coffee grounds that’s also transferred into a biofuel.

Transport for London operates the daily activities of public transit and the main roads of the city. Their goals are to listen to feedback while improving the system. They’ve constantly improved the technology and convenience, and another area they're working on is cutting down emissions from buses and other forms of public travel to make it safer.

It’s all led to Bio-bean, a British startup, to collaborate with Shell and Argent Energy to create a new source of biofuel from used coffee beans. The process begins with gathering these grounds from various cafes and restaurants that are stored after use. It’s all transported to a facility where they dry the grounds before extracting oil from them.
