Many people need their first cup of coffee to get going in the morning, and now some of London’s buses are also being powered by that energetic bean. The technology firm, Bio-Bean, created a coffee-derived biofuel by blending oil extracted from coffee waste with diesel fuel. The company extracts the oil from used grounds that it collects from coffee shops and factories. The coffee oil is then processed into a blended biofuel that it is perfectly fine for powering buses without the need for further modification. This is not the first time that Transport for London has turned to using biofuels to reduce emissions. Waste products such as cooking oil and tallow from meat processing are already being used in many of the city’s 9,500 buses.
