Shinkong Synthetic Fibers Invests $10 Million in Ambercycle’s Circular Polyester Plant

Shinkong Synthetic Fibers Corporation, a leading global polyester producer, has invested $10 million in Ambercycle’s first commercial facility, marking a significant milestone in their partnership. This investment will bolster Ambercycle’s ability to produce its premium recycled polyester material, cycora®, from end-of-life textiles on a larger scale.

The two companies have collaborated for three years, combining Ambercycle’s molecular regeneration technology with Shinkong’s extensive experience in the polyester market. This has enabled them to jointly manufacture regenerated yarns, meeting the rising demand for sustainable and circular materials.

“This investment signifies a crucial milestone in our endeavor to make circular materials widely available,” said Shay Sethi, Co-founder and CEO of Ambercycle. “We are excited to deepen our partnership with Shinkong. This investment enables us to scale up to meet the growing demand of our customers and push the boundaries of sustainable textile production.”

The demand for decarbonized polyester is on the rise, expected to reach 7 million metric tons annually by 2026, up from 5 million metric tons in 2015. This surge is driven by brands seeking circular materials to achieve their sustainability goals.

“Recognizing Ambercycle’s leadership in circular solutions, we are eager to support their expansion,” stated Eric Wu, Chairman at Shinkong Synthetics. “Investing in their new facility is not just a strategic move—it’s a commitment to pioneering a future with decarbonized polyester, which we see as critical to our business. This collaboration will further amplify our capacity to deliver high-performance, sustainable products to the global market.”

The new facility is expected to begin operations in 2026, further solidifying the partnership between the two companies. This strategic expansion will significantly enhance their ability to support circularity and scale next-gen materials within the textile industry, aligning with global efforts to transition towards more decarbonized production practices.
