Shell and bio-bean recently announced that together they are helping to power some of London’s buses using a biofuel made partly from waste coffee grounds.
The B20 biofuel contains a 20% bio-component which contains part coffee oil. The biofuel is being added to the London bus fuel supply chain and will help to power some of the buses, without need for modification.
Biofuel provides a cleaner, more sustainable energy solution for buses across London’s network by decreasing emissions.
“Our Coffee Logs have already become the fuel of choice for households looking for a high-performance, sustainable way to heat their homes – and now, with the support of Shell, bio-bean and Argent Energy have created thousands of litres of coffee-derived B20 biodiesel which will help power London buses for the first time,” said bio-bean’s founder Arthur Kay. “It’s a great example of what can be done when we start to reimagine waste as an untapped resource.”
The average Londoner drinks 2.3 cups of coffee a day which produces over 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. 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 litres 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.
