Coffee: it’s every workaholic’s go-to beverage and, astoundingly, perfect for manufacturing sportswear. Nowadays, it isn’t just perfect for a pick-me-up — it’s potentially fueling London’s signature double-decker buses.
“Instead of sending a tonne of waste coffee grounds to landfill where it degrades and releases methane and CO2, we collect it, recycle it and turn it into a renewable fuel which is then used to replace further conventional fuels – so it’s a double saving”, [said] Bio-bean founder Arthur Kay.
Among the heaviest Americano consumers, Londoners contribute up to 200,000 tons of coffee waste annually. To make the most out of discarded grounds, Bio-bean is extracting 6,000 liters of oil to mix into fuel. The final blend is of 20% biofuel, which will also help to reduce carbon emissions.
“We’re not saying that it’s going to totally replace fossil fuels overnight,” Kay said.
“The amount of diesel produced globally is always going to be more than the amount of coffee.”
Considering London buses run nearly 2 billion trips a year, Bio-bean’s initiative could encourage alternative energy use. Perhaps a beer fuel may even be in talks.
