A company from Cambridgeshire has become the first in the world to turn our obsession with fresh coffee into clean fuel.
Biobean take used grounds from hundreds of businesses and cafes across the country.
They then recycle them in a couple of hangars on the former RAF airfield at Alconbury.
The waste ground coffee is separated, sieved and dried then compressed into clean, solid fire logs.
Each log contains about 25 cups worth of granules. So far they have sold the equivalent of 20 million cups.
