Client’s Requirements
In 2020, the University of Dayton (UD) was searching for an on-site composting solution for food scraps from their dining halls. They were also interested in composting paper towels from their bathrooms as well as adding biochar as an amendment to their composting process.
They toured the Earth Flow composting system at the Food Bank in Dayton, Ohio and were impressed by the capabilities of the system.
Our Solution
Subsequently, University of Dayton purchased a 40’ long custom vessel Earth Flow system for their campus.
UD staff loads food scraps from their dining halls into the Earth Flow on a daily basis, using the optional Tote-Tipper. Wood chips are the primary bulking agent. UD also has experimented with different quantities of paper towels in their feedstock mix.
UD staff particularly appreciated the speed with which the Earth Flow converts feedstocks into usable compost. In 2023, the University of Dayton Earth Flow system was officially recognized by the Ohio EPA as a Class II Composting Facility.
