London Buses Are Now Powered by Coffee 😀 Like me!😻 Coffee waste from cafes, restaurants, and factories. They dry the grounds, extracting coffee oil with a biochemical process that uses a solvent. The oil is combined with other fuels into a hybrid B20 fuel, which can be used in diesel buses without any modification. Because of their high caloric content and valuable compounds, grounds make an ideal clean energy resource. https://buff.ly/2AncD2M
