Through the agreement, Shenghong will purchase Circ® PET chip to manufacture recycled-content filament yarn at commercial scale. The partnership expands Shenghong’s access to textile-to-textile recycled inputs while creating an additional pathway for Circ’s recovered polyester to reach the market through one of China’s leading fiber producers.

By combining Circ’s recycling technology with Shenghong’s manufacturing capabilities and market reach, the collaboration will broaden the availability of circular polyester materials for global fashion brands, textile mills, and other supply-chain partners. It also brings production closer to one of the world’s most important apparel and textile regions, helping support wider commercial adoption.

“Scaling textile-to-textile recycling requires more than breakthrough technology. It requires strong manufacturing partners with the technical expertise, capacity, and market reach to bring circular materials into the mainstream,” said Peter Majeranowski, CEO of Circ. “Shenghong brings all three. Together, we are creating a more direct path from discarded 

Shenghong Chemical Fiber New Material Co., Ltd., part of Shenghong Holding Group, operates an integrated platform spanning new materials and advanced textile manufacturing. The company has significant experience in differentiated functional fibers, recycled polyester, and direct-melt spinning technology, making it well positioned to support the commercialization of next-generation circular polyester products.

“This collaboration combines Circ’s textile recycling technology with Shenghong’s fiber manufacturing capabilities to help move circular polyester from innovation to broader commercial use", sasy Jason Tang, General Manager of Shenghong Chemical Fiber New Material Co., Ltd. "We look forward to working together to deliver high-quality materials that meet the needs of global brands and support the industry’s transition toward more circular production.”

The agreement is designed to help validate Circ® Polyester across commercial filament applications and establish a repeatable manufacturing model for future growth. By linking textile waste recovery with large-scale fiber production, Circ and Shenghong aim to reduce dependence on virgin fossil-based inputs and increase the availability of recycled polyester made from discarded clothing and other textile feedstocks.

The collaboration also reinforces Circ’s broader strategy of building regional manufacturing partnerships around the world. By working with established producers near major fashion supply chains, Circ can support customers with more localized access to circular materials while laying the groundwork for long-term global expansion.
