Trinseo has been working tirelessly on unlocking the recyclability of polystyrene. Our goal is to ensure that the material doesn’t end its lifecycle as waste and, instead, is reused productively for sustainable manufacturing and a positive environmental impact.
Trinseo has partnered with a network of providers throughout the value chain ranging from those that collect, sort, grind and purify. Today a systems approach is needed – no one can go at it alone.
Following is what we’ve been doing to make recycled polystyrene the reality that it is today. We invite you to join Trinseo as we grow our STYRON™ CO2RE™ portfolio and you continue on your sustainable solutions journey.
Dissolution
Trinseo manufactures recycled content containing resins using dissolution technology. With this approach, post-consumer recycled (PCR) material is dissolved in a compatible solvent to separate the polymer from contaminants. Following filtration, the material is fed into a reactor resulting in a polymer with 30 percent PCR content for use in a variety of applications including appliances, electronics, construction, consumer products and even food contact applications, if a functional barrier is used to ensure compliance.
Depolymerization
Trinseo has ventured into depolymerization, the ultimate in circularity that involves taking plastic waste back to its monomer state. Through a partnership with Indaver, a depolymerization plant in Europe will become operational later this year offering Recycled Styrene Monomer (rSM) to the marketplace.
We invite you to keep up to date on our efforts in the area of recycled polystyrene and sustainable solutions by subscribing to our e-newsletters. You can also read more about how Trinseo is partnering with Styrenics Circular Solutions to transform the styrenics industry by taking advantage of game changing technologies that will unlock polystyrene circularity, giving the material a second life and beyond.
