Coffee by-products are one of our biggest concerns environmentally on the farm, and we do a marvelous job at not only not polluting, but also using these by-products in a productive way. To date, our least productive by-product has been the coffee husk, with limited nutritional value to the soil, we have resorted to using it as mulching material on the hiking trails. We've recently found a new and more productive use for the coffee husk. We've constructed a stove with 9 burners that uses the husk as a fuel. This stove is a nine-burner circular stove built with walls of special fire resistant bricks and mortar.

It has a hole in the bottom through which the ashes fall down and air comes in. The top part of the burner is where the husk is loaded and pressed down until filled. It takes approximately 3 100-lbs sized bags of coffee husk to fill the 9 burners of the stove for one days use. There is not much actual fire in this stove, instead it is simply generating heat from the melting coffee husks. One of the wonderful side benefits of this stove is that it is essentially smoke free and it is using a waste product as fuel, not wood. We currently have one stove working and some more on the way. It is a great working stove that heats very quickly; a great benefit for heating water and cooking rice, beans, corn, soups, etc.. As the walls are made out of brick the cooker can get close to it without burning herself
