The North American Sodium Sulphate market remained stable in November 2025 due to continued stability in industrial fundamentals despite evolving structural changes. sodium sulphate remains a vital feedstock in the industry, including as an ingredient in detergents and glass production as well as in the kraft pulping process; however, long-term consumption trends are changing. producers in the United States reported stable operations due to lower demand for powdered detergents and the introduction of additional supply streams from lithium-ion battery recycling. the supply chain was stable, and lean inventories were maintained to meet rapidly changing market needs. though there was a decrease in demand for detergent-sector, industrial demand for glass, pulp & paper, and chemical processing remained solid. the future of the sodium sulphate market appears to be stable due to increasing industrial applications and development of a circular economy.
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.
