Regenyx, Pioneering PS Recycling Facility, Closes After Successful Five-Year Collaboration by Agilyx and AmSty. Regenyx, established in 2019 as the world's inaugural commercial-scale closed-loop chemical recycling facility for polystyrene (PS), has been a collaborative effort between Agilyx and AmSty. Nestled in Tigard, Oregon, United States, this pioneering facility embarked on a mission to transform PS waste into valuable resources through advanced recycling processes.

The initial vision for Regenyx, during its launch, foresaw the processing of up to 10 tons of PS waste daily, equating to an annual capacity of 3,650 tons. However, Agilyx's annual report for the year 2021 revealed that the facility had successfully processed a cumulative total of 4,400 tons between the years 2019 and 2021. In April 2021, Agilyx had already signalled that the facility was undergoing operational enhancements to optimize its efficiency. Fast forward to February 29, 2024, and Agilyx formally announced the decision, in conjunction with AmSty, to close Regenyx. This move comes after the attainment of objectives outlined in the five-year formation agreement. The cessation of plant operations is slated for April 30, accompanied by the phased wind-down of the joint venture.

Regenyx served as a crucial demonstration site for Agilyx's cutting-edge depolymerization technology, specifically focused on recycled styrene monomer production. Through this process, AmSty played a pivotal role in reprocessing the resultant feedstock into polystyrene resin and various products at its production facility. The collaborative efforts of Agilyx and AmSty, as highlighted in the joint statement, contributed to the diversion of over 6 million pounds (2,721 tonnes) of post-use polystyrene waste from landfills during the five-year duration of the project.

The decision to close Regenyx reflects not only the success of achieving set objectives but also the dynamic nature of the recycling industry. As the facility ceases operations, it marks the end of an era characterized by innovation and a commitment to addressing the environmental challenges posed by polystyrene waste.

Over the five-year span of the Regenyx project, the joint efforts of Agilyx and AmSty have not only showcased technological advancements but have also demonstrated the significance of collaboration in the recycling sector. The ability to divert millions of pounds of polystyrene waste from landfills underscores the positive environmental impact achievable through strategic partnerships and innovative solutions.

As the curtain falls on the Regenyx project, the industry will undoubtedly be watching to see how the experiences gained and knowledge accrued will shape the future landscape of chemical recycling. The lessons learned from Regenyx will undoubtedly inform future initiatives, ensuring that the industry continues to progress towards more sustainable practices and solutions.
