used coffee pellets

daily coffee habits turned from waste to pellets by Bio-Bean:

"(...) Bio-Bean has launched a UK-wide collection service and opened a waste coffee recycling factory. This factory turns the material into biomass pellets, used primarily for fueling large industrial boilers at places such as supermarkets, offices, homes, airports and factories at the moment. The company is now able to handle up to 10% of the country's grounds each year, or about 50,000 tonnes, which is said to be the equivalent amount of energy for fueling some 15,000 homes."

"It's a carbon-neutral fuel that not only happens to have a higher calorific value than wood, according to Kay, making it a great fuel option, but that is also cheaper than most of the alternatives. It also happens to be something that the suppliers, the coffee shops, need to get rid of as a course of doing business, so it's a win/win situation."
