Americas Styrenics LLC, the largest polystyrene producer in the Americas, and Agilyx Corp., an advanced recycling technology company, say they have successfully developed a closed-loop recycling solution — from waste aggregation to the production of new material — for polystyrene.
At Regenyx, the commercial-scale joint venture facility operated by the two companies in Tigard, Ore., collected PS waste is currently being transformed into liquid styrene, in a process called recycled styrene monomer production. This feedstock is subsequently reprocessed into PS resin at an AmSty polystyrene production facility.
The companies have now obtained ISCC PLUS certification (International Sustainability and Carbon Certification) for this "circular recycling pathway for polystyrene recycling," as Agilyx CEO Tim Stedman described it. "We are proud of the work that has been done at the Regenyx facility to accelerate the available capacity of recycled content for producers."
Through the ISCC PLUS certification process, recycled content can be assigned, certified, and claimed by package manufacturers. Consumers can readily identify circular products on the shelf, which will help them make conscious decisions about opting for sustainable choices.
"With this achievement, we can begin moving circular recycled products from concept to reality, and directly into the hands of consumers," Tim Barnette, vice president of polymers and sustainability at AmSty, said.
Americas Styrenics is based in The Woodlands, Texas. The company a joint venture equally owned by Chevron Phillips Chemical Co. and Trinseo. AmSty is working toward a goal of using 25 percent recycled content in all foodservice and food packaging applications by 2030.
