MRF’s Polymer Center Network to Expand Access to Recycled Plastic

A first-of-its-kind facility from Republic Services allows the MRF to aggregate plastic from its regional facilities for further sorting and recycling, resulting in high-quality PCR material.

Republic’s new Las Vegas Polymer Center opened in December and is expected to produce more than 100 million lb of recycled plastics each year.

There’s good news for brands struggling to source enough high-quality recycled PET, recycled high-density polyethylene, and recycled polypropylene to meet both EPR regulations and their internal packaging goals. Republic Services, the second largest provider of waste disposal services in North America, has launched a first-of-its-kind operation in the U.S.—one of at least four planned by the company—designed to sort and process plastic packaging waste to help meet the growing demand for recycled material. The new Polymer Center, located in Las Vegas, opened in December and is expected to produce more than 100 million pounds of recycled plastics each year, specifically PET flake and color-sorted HDPE and PP, for use in sustainable packaging and other applications.

“In its simplest description, the Polymer Center provides secondary processing of recycled plastics to produce higher-quality materials for different end markets.” That’s according to Pete Keller, Republic Services’ vice president of recycling and sustainability, who shares that the regional hub-and-spoke model of the Polymer Center network enables Republic to send curbside-collected and baled plastics from a number of its regional MRFs (material recycling facilities) to a single center for further sortation and processing into multiple, high-quality grades of PET flake and HDPE and PP resins.

As Keller explains, the Polymer Center network addresses several barriers to circularity for plastics. Among them is the small percentage of plastics that make their way into a MRF versus the complexity and investment required to sort them. “On average, only 7% to 8% of the curbside recycling stream that Republic processes are plastics,” he says. “It’s a small percentage of what’s being processed overall. Seventy to 75% of what we make and sell is fiber-based, such as paper and cardboard. So the focal point of our operation is processing those materials.”

MRFs typically sort and bale four grades of plastic: PET, notably beverage bottles, natural or non-pigmented HDPE from milk jugs, pigmented or colored HDPE, which results in a bale of mixed colors, and “everything else,” i.e., polyvinyl chloride (PVC), low-density polyethylene (LDPE), PP, polystyrene (PS), and “other.” Increasingly MRFs are sorting and baling PP separately for a fifth grade. To sort further, or fractionate, additional grades or types of resins locally “just doesn’t make sense economically,” Keller says.
