Rumpke, a waste and recycling company headquartered in Cincinnati, has expanded its Columbus, Ohio, material recovery facility (MRF) with the installation of a single-stream processing system provided by Machinex, Plessisville, Quebec. The new system expands on the sorting capability of the MRF’s phase 1 system, separating old corrugated containers (OCC) from single-stream recyclables.
According to Machinex, Rumpke wanted the new system to be able to process 30 to 35 tons per hour of recyclables with minimal reliance on manual sorting.
The Machinex system starts with a second pre-sort system to collect small pieces of OCC, boxboard and chipboard while removing plastic bags. A scalping screen and fines screen device was included to break glass and divert the less-than-4-inch fraction directly to the finishing screen. Multiple ONP screens have been installed to ensure maximum efficiency in sorting old news (ONP) while minimizing labor associated with manual sorting, according to Machinex.
The container sorting line includes flat fraction separators, magnets, an eddy current, optical sorting units and a glass cleanup system.
Rumpke’s Columbus system is the first complete single-stream plant that Rumpke and Machinex have completed together, according to the equipment company.
“Machinex adapted well to a unique situation,” says Jonathan Kissell, Rumpke corporate communications supervisor. “Rumpke has had a good experience with Machinex on several projects, including the renovation in Columbus and an aluminum can processing system in Georgetown, Ky.”
