The Recycling Committee of SPI: The Plastics Industry Trade Association, in a paper titled “Compatibilizers: Creating New Opportunity for Mixed Plastics,” aims to increase awareness about the potential for compatibilizers, and provide information about the commercially available compatibilizers out on the market today so recyclers can explore the potential to create value out of mixed streams that are not currently being recycled.

WASHINGTON—The Recycling Committee of SPI: The Plastics Industry Trade Association released a paper titled “Compatibilizers: Creating New Opportunity for Mixed Plastics” Tuesday providing the entire recycling value stream a primer on compatibilizers, which are additives designed to make disparate, traditionally incompatible varieties of post-consumer recycled plastic materials compatible.

“Relying on the expertise and range of experience in the plastics supply chain, the SPI Recycling Committee has created yet another product that provides the concrete tools and insight every company in the plastics recycling value stream needs in order to move toward a truly circular economy for all plastic materials,” said SPI President and CEO William Carteaux. “Compatibilizers, long used by the prime industry, offer the potential to create new mechanical recycling solutions for post-industrial and post-consumer scrap plastics. This project demonstrates the innovation that can happen in recycling when you engage all segments of the supply chain. This is a real world solution being offered, one which is currently being used today by a number of our members to recover mixed resin streams that would otherwise be landfilled.”

The Recycling Committee’s report found that widespread use and understanding of compatibilizers could present recyclers with the opportunity to convert multi-layer flexible packaging and highly mixed streams, such as the yield loss from increasingly contaminated bales (bales comprised of several different types of plastics rather than one, variety), into valuable recycled resin. “Recent findings suggest HDPE recyclers are suffering a 20-percent yield loss, while their PET recycling counterparts are experiencing upwards of 40-percent yield loss,” the report says. “This rate of material loss can quickly change the economics of an operation from black to red.”

“If that yield loss could be put to use as another valuable feed stream, it can dramatically change the economics of an operation, as well as further divert valuable plastics from the landfill,” the report adds, noting that compatibilizers are one means by which those mixed plastics could provide a greater source of profit for recyclers.

“Compatibilizers: Creating New Opportunity for Mixed Plastics” aims to give recyclers the information they need to begin to explore the potential of compatibilizers and provides a list of the products available for recyclers to start using these additives to enhance their bottom line.

"From resin suppliers and equipment makers to processors and brand owners, SPI is proud to represent all facets of the U.S. plastics industry," said William R. Carteaux, president and CEO, SPI. "Our most recent economic reports show that the plastics industry as a whole is resilient, and has come through the recession significantly better than other U.S. manufacturing sectors."
