With a capacity of 25 tons per hour, the 57,000-square-foot facility is expected to receive more than 50,000 tons per year of recyclables from Charleston County curbside collection. For the past two years, the county has been shipping its recyclables to Horry County, South Carolina, for processing while it has been planning for the recycling center.
The system includes advanced sorting technologies, such as a drum feeder, a bag opener and a series of separators -- a Mach OCC (old corrugated containers) screen to sort the cardboard, a Mach One News to separate residential papers and a Mach Ballistic to be used as a finishing screen to increase the quality on mixed fiber.
Two Mach Hyspec optical sorters will be installed; the first one is a dual-eject unit that will sort polyethylene terephthalate (PET) bottles and fiber with the same machine, while the second one is a dual-channel unit that will sort high-density polyethylene (HDPE) on the first channel and do an HDPE color sort on the second channel. Also included in the system are ferrous and nonferrous separators, a light fraction separator on glass, an aspiration system linked to a closed-door baler for plastic film and two trash compactors for system residue.
"We have worked closely in partnership with the county to design a system that handles their needs of today while maintaining flexibility for future changes in the material stream”, says Rusty Angel, Machinex eastern region sales manager. “This MRF will be the largest, most-advanced recycling center in the entire state of South Carolina and Machinex is happy to be a part of that progress.”
