In the penultimate week of December 2025, the U.S. Formic Acid FOB Texas market started with a bearish sentiment, falling 1.88% due to continued feedstock availability and increasing inventories at the Gulf Coast, before making a slight rebound of 0.64% in the final week, contrasting the severe bearish trend for 12 weeks. Smooth supply chains (no maintenance, no rail issues, no import interruptions) allowed normal plant rates, resulting in growing merchant volumes against stable domestic offtake. Milder weather curtailed demand for de-icing products, while stable poultry feed and leather-tanning consumption provided support, but no surprises on the upside. There was no freight congestion, no exchange rate volatility, no sudden spikes to offset demand, but rare higher spot availability for sellers, while buyers postponed their purchases. The late-week rise was on the back of a more positive tone amid sustained buying and relatively steady formic acid production, which was close to neutral by the end of the year.
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.
