BEL Farms in Minnesota composts horse manure and pelleted bedding in their O2Compost Benchmark System. The finished product is used on their own property and "the neighbors are much happier with a reduction in flies and odor."

The owners of BEL Farms installed an O2Compost System at a previous farm in 2005 but had to leave it behind when they moved to a new location. The first system worked so well they installed a second, 4-bin system at the new farm.
