History & Milestones

AmSty is formed through the joint venture between Chevron Phillips Chemical Company (CPChem) and The Dow Chemical Company (Dow). Many employees from the original parent companies are still with AmSty today – which is a testament to AmSty’s mission, vision, values and company culture. Dow ownership is transferred to Trinseo (formerly Styron) in 2010.

The PolyRenew® brand of resin is launched as the first post-consumer recycled polystyrene product with FDA approval for foodservice in the United States.

PolyRenew® resins are first used in recycled foam containers.

AmSty commits to ACC as a charter member of their new alliance, focused on innovation and circularity for the plastics industry.

ST. JAMES DEEPWATER DOCK

Construction is completed on the deep-water dock in St. James, Louisiana, providing AmSty’s styrene facility along the Mississippi River the capability to load and unload large oceangoing vessels.

AMSTY CONTRIBUTES TO FUNDING RECYCLING

infrastructure as a founding member of the Foodservice Packaging Institute’s Foam Recycling Coalition.

Major polystyrene plant modernization is completed with upgraded process control systems.

AmSty is recognized by the ACC for their commitment to safety, achieving top quartile safety performance as measured against ACC peers.

AmSty forms Regenyx, a joint venture with Agilyx, to commercialize an innovative circular recycling process that breaks down polystyrene into its original raw material. It can then be used to make products with the same quality and durability as the original polystyrene. AmSty’s long-term vision is that polystyrene products should never be landfilled but reclaimed, reprocessed and reused again and again.
