In August 2025, international tallow fatty acid saw prices at multi-year highs as commodity analysts observed a real paradigm shift in the perception of tallow from a byproduct of the meat sector to an input in renewable energy story. The rally was driven by stronger industrial tallow fatty acids demand, poor livestock supply conditions, and odd trade flows with tallow positioned as an eligible feedstock in the global biofuels transition.
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.
