Trinseo, a global materials solutions provider and manufacturer of plastics and latex binders, and Indaver, a leader in sustainable waste management in Europe, have signed an offtake agreement for recycled styrene (r-styrene).
Under the terms of the agreement, Trinseo will buy a minimum of 50 percent of the r-styrene produced at Indaver for a 10-year period, following startup of the plant planned in 2023.
As with its other waste collection processes, Indaver will collect post-consumer polystyrene (PS), such as yogurt pots and single-use packaging, and recycle and produce the r-styrene through a proprietary depolymerization technology at its Antwerp, Belgium site. The r-styrene will then be sent to Trinseo’s Tessenderlo, Belgium site nearby and will be used to manufacture recycled PS resins for dairy packaging and other applications. Both the r-styrene and r-PS products will be ISCC Plus mass balance certified.
