Machinex provides upgrades to modernize Republic Services’ Greensboro, North Carolina, MRF

Machinex, Quebec, announced it has provided an upgrade to Republic Services’ single-stream material recover facility (MRF) in Greensboro, North Carolina, to increase productivity and recovery rates while reducing cleaning times.

Republic chose to modernize its 20-year-old facility after its contract with the city of Greensboro was renewed in order to efficiently handle the incoming recyclables.

Machinex designed a single-stream system to process 30 tons per hour of residential and commercial material within the current building while reusing some of the existing structural work and baler feed conveyors.

The system includes a new drum feeder and infeed system, OCC screen, fines screen, three ballistic separators, a glass cleanup system, an optical sorter for PET and HDPE, as well as a new magnet and eddy current separator.

The main processing system is new and includes Machinex’ MACH Ballistic separators as the primary and secondary screening devices after the OCC and fines screens. No rubber discs are utilized in the system. According to Machinex, the system will minimize aluminum loss since the ballistic separators do not use rubber discs that can wear over time, thus increasing the initial screen opening. Its elliptical movement will also not wrap film or other stringy material, resulting in less maintenance, downtime and operational costs, Machinex says.

“Before having MACH Ballistic separators, the operator was spending 3 hours per day to clean their disc screens. Since the upgrade, that has been reduced to only 10 to 15 minutes per day. Cleaning screens in MRFs is a big deal because when you are cleaning screens, you are not producing the material. The upgrade, particularly the MACH Ballistic, helped the customer achieve a 95 percent runtime,” Rusty Angel, Machinex eastern region sales manager in the U.S. for Machinex, says.

“Our client liked our design and appreciated having our U.S. offices about 20 minutes away,” Angel concluded.
