China Soy protein isolate market indicated stabilisation in September 2025 as prices settled after a consistent pattern of descent in February to August. The soy protein isolate category experienced a small 0.6% boost as food processing demand regained vigor in anticipation of the autumn production season, the first direction change following seven monthly declines.
Industrial purchasers revived guarded purchasing efforts, and Southeast Asian market export demand for soy protein isolate added additional price support. Recovery was supported by strengthening demand among plant protein producers and consistent utilization within pharmaceutical applications. Supply side fundamentals were offset by domestic use of production hardening to 78% from previous month's level of 72%.
Key market movers of soy protein isolate were declining soybean meal prices, which cut raw material prices, and lower container freight rates that enhanced export competitiveness. Prices are expected to continue at present levels through Q4 2025, and trade is expected within the range.
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.
