Prices of Subtilisin Enzyme in China have remained firm in early September 2025, following a surge in August. Tight inventory levels following a production slowdown in July due to plants shutting down, and strong demand from both food and beverage processing and breweries are helping to sustain the bullish momentum. Uninterrupted logistics and supply chains ensured Subtilisin Enzyme availability. Meanwhile, a significant decline in the US Dollar against the Yuan prompted exporters to adjust their pricing upwards, supporting price increase. Demand firmed as a result of increased offtake and increased importer engagement, coupled with a 90-day tariff truce between Washington and Beijing. Market participants had indicated that Subtilisin Enzyme prices could increase sharply towards late September, low stocks and ongoing demand currently enable forward purchasing. The outlook for the Subtilisin Enzyme market remains firm and projected for continued pricing strength.
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.
