The UK alone produces 500'000 tonnes of coffee grounds every single year, many of which are landfilled and produce large amounts of CO2. The British company bio-bean has developed a techology to turn ground coffee waste into heating pellets that are around twice as energy-rich as common wood pellets. One tonne of recycled coffee can reduce CO2 emissions by up to 7 tonnes.
