Earthworms turn leftover coffee pulp into compost, biogas

The Rogers Family Company – a California-based, international roaster of “Fairly Traded” and “Direct Trade” gourmet coffee – is deploying a ‘green’ army of billions of red earthworms to create nutrient-rich, organic fertilizer to help small coffee farmers and promote organic coffee production in Central America and Africa.

The worms also aerate the soil and clean up the water. They use no pesticides or fertilizer on their coffee trees.
