Will buses be run on coffee in future? Now, we can definitely say it will become possible. The world has positive news from London. There, a start-up named Bio-bean has made this possible by fuelling country’s iconic double-decker buses with leftover coffee grounds.
The fuel is made from oil extracted from used coffee grounds and blended with diesel.
How is it manufactured?
Bio-bean gathers grounds from small cafes to big coffee chains and even instant coffee factories. The grounds are then brought to the bio-bean plant where they are dried and coffee oil is extracted. The extracted oil is then blended with other fats and oils to create a “B20” biofuel, which is further mixed with traditional mineral diesel. This mixed fuel offers10-15 percent reduction in CO2 emissions as compared to pure diesel.
Bio-bean claims that Britain produces nearly 500,000 tonnes of coffee grounds a year and it is enough to power a third of London’s entire transport network. Bio-bean’s plant has the capacity to recycle 50,000 tonnes of grounds a year.
Bio-bean was founded in 2013 and has received fund from the UK government.
