Shell and bio-bean partner to produce B20 biodiesel using waste coffee; fuel for London buses
. . . .The average Londoner drinks 2.3 cups of coffee a day, resulting in more than 200,000 tonnes of waste a year, much of which would otherwise end in landfill with the potential to emit 126 million kg of CO2, according to bio-bean. bio-bean works to collect some of these waste coffee grounds from high street chains and factories.
The grounds are dried and processed before coffee oil is extracted. bio-bean works with its fuel partner Argent Energy to process this oil into a blended B20 biofuel. 6,000 liters of coffee oil has been produced, which if used as a pure-blend for the bio component and mixed with mineral diesel to form a B20, could help power the equivalent of one London bus for a year.
