"We have been using this system since 2011 and we are a huge fan." Mary E.'s Micro-Bin system composts the manure (no bedding) from her two horses. In three months' time, the finished compost is spread in the turnout ensuring no mud in the naturally sandy and porous soil. "With all the monsoons, we are the only ones who can walk in their turnout." The compost is also used when planting trees. Construction/use of their O2Compost system has more than paid for itself by avoiding hefty waste management fees and an HOA-required screen. Mary's final words?  "NO ODOR, NO FLIES"
