A clean technology company, bio-bean has industrialised the process of recycling spent coffee grounds into advanced biofuels and biochemicals. It was the company’s Coffee Logs that captured the attention of the judges thanks to its simplicity and environmentally friendly nature. Coffee Logs are quite simply, a fuel for stoves, wood burners and chimeneas. The difference comes from the fact that the logs are each made from 25 cups of spent coffee grounds. These compressed coffee grounds produce more heat and burn longer than wood, making them not just cost efficient but help to lower emissions and reduce waste.
