Coffee Pulp produces 80% of the weight of a coffee harvest, but has traditionally been used for little more than mulch. During heavy rains, piles of coffee pulp can contaminate groundwater and streams.

Sustainable Harvest is training residents of Tanzania, mostly women, to grow protein-rich mushrooms on dried coffee pulp. After the mushrooms are harvested, the remaining pulp is much better feed for livestock than pulp that has not been used as a substrate for mushrooms.

This provides a valuable protein source, protects the water supply, improves livestock production, and reduces waste.
