What if the waste coffee grounds could also produce energy to help power the planet? That’s exactly what bio-bean, a company supported by Shell, does.

At bio-bean’s factory, the grounds are recycled into biomass pellets and Coffee Logs – a carbon neutral fuel for the home. Both make excellent fuel for heating buildings.

But it needn’t stop there. Research is now heading towards liquid fuels and biochemicals. Each tonne of waste is capable of making up to 250 litres of biofuel; enough to run a London bus for 3.5 days.

Every tonne of waste coffee grounds recycled using bio-bean's technology saves 6.8 tonnes of CO2 emissions. Which is like driving from London to Beijing, twice. It is a perfect example of the new circular economy.

Each year bio-bean recycles thousands of tonnes of waste coffee

The Coffee Logs were launched for sale on Amazon, rapidly becoming the best-seller in Home and furniture section.

Users started using Coffee Logs to heat their own houses, and left hundreds of good reviews.
