The global markets of glucosamine have moved in opposite directions in the first half of October 2025. The nutraceutical manufacturers have accelerated their purchases to build glucosamine inventories for increased winter production runs of bone and joint supplements in the Asia Pacific market. The inventory dynamics have prompted the glucosamine suppliers to adopt strategic pricing and tighten available spot volumes. The markets in North America have entered the month with comfortable stocks after strategic procurement in previous months. The sufficient inventory has reduced the urgency to replenish which has exerted a downward pressure on US export quotes. The seasonal anticipation, inventory management choices and supplier allocation strategies have bifurcated the markets. ChemAnalyst expects that the glucosamine prices will likely firm globally as winter production demand persists and inventories at supplier and distributor levels will tighten further. The buyers and procurers should avoid panic spot buying and instead quantify realistic consumption for Q4 2025–Q1 2026.
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.
