Coffee waste extracts work as biofuel
In a novel development, biofuel has been made from waste coffee grounds that is now powering London’s buses. According to a joint news release by Shell and technology firm Bio-bean, coffee oil is extracted from coffee waste and biofuel is created by mixing it with diesel which can be added to the London bus fuel supply chain without any need for modification.
Working with biofuel producer Argent Energy, the final fuel blend is made up of 80 per cent traditional diesel, and 20 per cent biofuel. The development of the new fuel will help to decrease emissions by buses paving the way for a cleaner, more sustainable energy solution.
Over 200,000 tonnes of waste a year is generated by the average Londoner who drinks 2.3 cups of coffee a day. Bio-bean plans to collect these waste coffee grounds from high street chains and factories.
So far, 6,000 litres of coffee-derived biodiesel has been produced, which could help power a bus for a whole year. Bio-bean's founder Arthur Kay said that it’s a great example of what can be done when we start to reimagine waste as an untapped resource.Shell Singapore said the technology "holds much potential for heavily motorised countries".
