The coffee industry plays a major role in the global economy. It also has a significant impact on the environment, producing more than 2 billion tons of coffee by-products annually. Coffee silverskin (the epidermis of the coffee bean) is usually removed during processing, after the beans have been dried, while the coffee grounds are normally directly discarded.
