Back in 2002, Peter Moon's neighbor (Daryl P.) heard he was experimenting with composting, so he contacted O2Compost to see how we could help him with his horse manure pile. Using an existing building, we constructed a simple aerated static pile system and with three months, we had converted a $750/month expense into a $500/month profit center for the farm. Daryl said, "Before, I had a manure problem ... now I don't seem to have enough horses."
