Covation Biomaterials, a biomaterials company focused on advanced bio-based materials, has announced the mechanical completion of its first commercial plant for the C4 product platform.

 

The facility will produce bioTHF and bio-based polytetramethylene ether glycol (PTMEG), marking a major step in scaling renewable chemical production.

 

Alongside the milestone, the company has officially launched the Xatryx brand, which will cover its new portfolio of non-food, bio-based PTMEG products manufactured at the site.

 

The development represents a significant move toward the defossilization of materials production, as CovationBio pushes to expand renewable alternatives in global chemical supply chains.

 

Located in Qidong, Jiangsu Province, China, the C4 facility is built around a proprietary process technology developed in-house by CovationBio. The project carries a total investment of RMB 10 billion and is being developed in three phases. Once fully complete, it is expected to reach a total capacity of 500,000 tons per year of bio-based materials.

 

Phase one—now mechanically complete—delivers 50,000 tons per year of commercial capacity for both bioTHF and bioPTMEG. Commercial production is scheduled to begin in the second half of 2026.

 

Feifeng You, President of CovationBio, commented: "The Xatryx name conveys our spirit of relentless exploration to develop processes and products that deliver high performance and support defossilization of the materials industry. 

 

"As an important building block, Xatryx products provide many possibilities to improve one's quality of life while taking good care of our planet. To achieve this, we leverage an abundant, non-food, agricultural by-product that is directly converted to a chemical feedstock, which our Advanced ThermoChemical technology uses to create Xatryx products."

 

The company says the platform is designed to turn agricultural by-products into high-value chemical feedstocks using its Advanced ThermoChemical technology—positioning Xatryx as a key material in next-generation sustainable manufacturing.
