The Adipic Acid Technical Grade (DEL Houston) prices in the U.S. were stable for the week ending 12 December 2025, as the market was influenced by a relatively balanced supply and demand situation and cautious year-end purchase activities. Production was supported by feedstock trends that partially offset each other, with upstream benzene increasing and the feedstock cyclohexanone remaining stable, reducing the overall production costs and the profit margin continuing to stable. Domestic manufacturing activity compounded steady output and import streams from Asian and European market were solid. Demand was representative of supply steadiness with production and sales of automotive staying at baseline level for engineering plastic, and solid demand for apparel amid Black Friday contributing to remain procurement despite soft retail sentiment. Electronics and other sector also saw only routine uptake. With an outlook for balanced feedstock economics, disciplined production, and moderate downstream demand, no strong upside in adipic acid prices during this period.
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.
