Coffee perks up mushrooms

If you drink coffee you create used coffee grounds. But they don’t need to end up in landfill. In the English seaside town of Brighton, the Espresso Mushroom Company has turned something that is normally discarded into an asset. Twice a week it collects used coffee grounds from up to 10 cafes in the town. That is the equivalent of about 200 kilograms a week – or almost a tonne a month. Those coffee grounds are then taken to a farm, where they are used as compost to grow mushrooms.
