To get this project underway, thousands of yards of dirt on the campus’s periphery had to be moved to prepare the site and many yards of concrete were poured to construct the base of a metal pole barn, which would eventually house the composting machine.

Hauled by truck from Ottawa, Canada, the enormous composting machine was unloaded by crane and placed on the concrete pad.

The vertical posts were installed and metal siding attached. For power, electricity was connected and the solar array installed. Today, the Ohio University Composting facility also boasts a solar thermal system and waste oil heaters that use leftover oil from the university’s facilities operations. Skylights provide indirect lighting. The entire facility is self-sustainable. With a 10 kilowatt-per-hour built in 2009 and a 31.1 kilowatt-per-hour system added in 2012, the solar array produces more energy than is used in the operation.
