HISTORY & MILESTONES

Today, AmSty is a leading integrated producer of polystyrene and styrene monomer, offering solutions and services to customers in a variety of markets throughout the Americas. Below is a brief timeline showing the story of how the company came to be what it is today and some major milestones that contributed to its success.
  • 2008
    The joint-venture formation of AmSty originally took place between Chevron Phillips Chemical Company (CP Chem) and The Dow Chemical Company (Dow) in May 2008. Dow ownership was transferred to Trinseo (formerly Styron) in 2010.
  • 2011
    PolyRenew® brand resin launched as first post-consumer recycled polystrene product with FDA approval for foodservice in the U.S.
  • 2014
    Completion of multi-year Enterprise Organization Strategy (EOS) redesign and implementation of SAP’s ECC 6.0 Suite, HANA enterprise software and HANA Enterprise Cloud.
  • 2015
    Construction completed on the deepwater dock in St. James. AmSty becomes first styrene facility along the Mississippi to allow access for loading large ocean-going vessels.
  • 2017

    Major plant modernization completed with upgraded control systems.

  • 2018

    Top-quartile safety performance on a 3-year-rolling-average basis among chemical manufacturing peers, according to ACC data.

  • 2019

    AmSty forms Regenyx, a joint venture with Agilyx, to commercialize a new way of recycling polystyrene. With this process, polystyrene waste is collected, converted back to original feedstock, then remade into original products again. We call this the PolyUsable cycle; a way to recover and reuse products that were once single-use.


AmSty is a proud member of the American Chemistry Council® (ACC) and a participant in its Responsible Care® initiative. Involvement in the Responsible Care initiative helps AmSty to "improve in environmental, health, safety and security (EHS&S) performance for [all of our] facilities, processes, and products."
