U.S. polystyrene prices rose through mid-May 2026 as strong domestic production, rising feedstock costs, and global disruptions supported a continued uptrend. Domestic suppliers met of demand, keeping supply steady and exports to Latin America flowing despite global instability. High Gulf Coast operating rates kept polystyrene availability healthy, but volatile benzene and styrene costs—driven by crude disruptions from the Middle East conflict—pushed prices higher. Global petrochemical prices have surged nearly 50%, contributing to rising U.S. inflation. With crude flows restricted and freight and insurance costs elevated, polystyrene markets face ongoing volatility. Prices are expected to remain firm through late May, though short-term fluctuations are possible.
Selenis has effectively manufactured recycled PET chips using terephthalic acid sourced from Circ®, a textile-to-textile recycler based in Virginia. The chip production took place through a series of batches at Selenis' pilot plant in San-Giorgio, Italy. By utilizing inputs recovered from polycotton textile waste, Selenis has created high-quality PET chip, which has been further processed into DTY yarn. This yarn will play a crucial role in product development as Circ prepares for additional capsule launches. Selenis is leveraging the success of this initial collaboration phase and is committed to advancing towards an offtake partnership to support Circ's inaugural industrial facility.
Eduardo Santos, Head of Corporate Strategy at Selenis, remarked that the monomer synthesis showed a performance comparable to virgin terephthalic acid. He expressed optimism about the consistent quality of Circ's monomer output and anticipated future commercial success. Santos pointed out that the Circ partnership complements Selenis's existing mission and goals for a more sustainable textile industry. He further stated their anticipation of expanding upon this collaboration and providing support for Circ's forthcoming commercial production trials.
