This Benchmark system was built by H. Ong to compost the manure and bedding (shavings and pellets) from his four horses. We love the creativity and personalization feature of this nicely-built system. He is planning to sell the finished compost.

"The O2Compost team is very approachable and giving of their time. They are also very attentive and interested in our project."   H. Ong
