Eco Coffee: Turning coffee into fuel

How does it work?

The grounds are collected from their customers when they make deliveries of fresh coffee, ensuring a carbon neutral journey is achieved. Back at base, they sieve the grounds to remove any foreign objects. Once the grounds are dried, they are pressed through a die, forming the Bio Fuel ready for the Eco Roaster. The Eco Roaster turns the Bio Fuel into heat energy to roast the fresh coffee: 40g of Bio Fuel roasts 1kg of fresh coffee and any excess heat is stored to heat the roastery. Finally, the beans are quickly cooled, de-stoned and packed in valve bags to lock in the freshness.

Grounds are also made into 'Eco Coffee Logs', which can be used in wood burning stoves and domestic fires.

Recycled coffee grounds not only produce an environmentally friendly energy source but they also avoid going to landfill. Coffee grounds accelerate the decomposition of other food waste. This produces methane, which has more than 20 times the global warming capacity of carbon dioxide.
