In a move to become more environmentally friendly, Melita B. and her husband built this Micro-Bin system to manage the manure and pine pellet bedding from their four "amazingly wonderful mares". The finished compost will be used in her vegetable garden and as stall bedding. The O2 Compost system has turned out to be "much easier to use than lifting muck buckets into the dumpster. The design of the removable boards in the front ... makes dealing with the stall muck much less strenuous on the arm muscles."
