PreZero US, headquartered in Los Angeles, says it is purchasing source-separated postconsumer film, including low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), for domestic mechanical recycling at its recently opened environmental campus in Jurupa Valley, California. The company also has invested in a facility in Westminster, South Carolina, where it will process postconsumer film. PreZero US says it will pay competitive prices for the material.
This announcement follows an earlier call for mixed plastics to be processed at the Westminster site.
Acceptable inbound material includes flexible film, bubble wrap, shrink wrap and grocery bags. This material is accepted as Grade A and Grade B bales, which are then shredded, washed and pelletized.
In Jurupa Valley, PreZero already has begun processing LDPE and LLDPE into what it describes as “consistent, high-quality resins” that it has branded as CoreFilm. The company says it has the capacity to ship this material on a truckload basis.
The company's minimum requirements for Grade A LDPE/LLDPE include less than 5 percent contamination in the form of color/print/labels, less than 2 percent contamination in the form of high-density polyethylene bags and less than 1 percent contamination in the form of strapping. Grade A material must be 95 percent clean, dry and clear.
PreZero’s minimum requirements for Grade B LDPE/LLDPE include an acceptable contamination of less than 10 percent in the form of strapping, polypropylene film, injection grade tubs, loose paper and bubble wrap. Grade B material must be clean, 80 percent clear and up to 20 percent colored.
In the effort to advance the circular economy, PreZero says it wants to form lasting relationships with the companies it sources material from. Once the feedstock is processed, PreZero will look to sell the resulting 100 percent postconsumer resins (PCR) back to the manufacturers that supply the feedstock-generating companies.
The company says all CoreFilm resins will undergo testing for quality and consistency in an ASTM certified laboratory, ensuring manufacturers have the data they need for seamless PCR integration in their molding processes to create new products.
