Turning Used Coffee Grounds Into Gold

A former British architecture student has found a way to turn used coffee grounds into flammable bricks that can be used as fuel for wood-burning stoves, at the same time reducing food waste. The technology involves removing the oil from the grounds – collected from coffee shops, retailers, airports and coffee factories – then compacting them. The coffee bricks then burn without any coffee aroma. So far, Bio-bean has dealt with companies that spend a lot of money to transport and then dump the used grounds in landfills. The company picks up the waste grounds, processes them, and sells them back to their clients as cheap fuel. Bio-bean feels consumers will also save a lot of money burning coffee ground briquettes rather than conventional charcoal, wood, or coal.
