Manueldr's Coffee Cup is made from coffee grounds, pressed into a vessel by a special machine on the spot. A wax made from soy is mixed with the coffee grounds and pressed into a waterproof cup. This cup can later be thrown in a compost heap to degrade and also fertilize new plants. Coffee grounds are high in nitrates which is nutrient gold for plants. I just wonder how well the coffee cup can stand up to the uneven pressure of someone's hand as they hold the cup. I feel like a slight bend in the side of the cup would cause it to crack and spill hot lava coffee all over your lap. I would like to try it though!
