Sweden is ranked number four in coffee consumption around the world. Coffee grounds are re-used in compost or many other ways, can we find a new way to re-use coffee waste? I received two buckets of coffee grounds from Casa Progreso, the idea was to mix coffee and clay, and ram it to see the results. It was very interesting to see the possibilities of this combination; but, since coffee is an organic material it can mould. Maybe a different way of drying the rammed coffee would help?
