Westlake Corporation (NYSE: WLK) announced that its Westlake Epoxy plant in Deer Park, Texas, has received International Sustainability & Carbon Certification (ISCC) PLUS certification. The certification covers liquid epoxy resins, solid epoxy resins, and liquid epoxy blends that combine liquid epoxy resins with reactive modifiers.

The certified products serve industrial coatings, construction, wind energy, composites, automotive and electronics segments. Customers can now access ISCC+ mass balance-attributed content of certified renewable feedstock while maintaining the same quality, performance, and specifications as standard epoxy resins.

"This is an important milestone for Westlake Epoxy in North America and a key step in bringing more renewable raw materials into our global supply chain," said Brian Powers, Senior Vice President, Performance & Essential Materials.

The Deer Park certification allows Westlake to offer U.S.-made epoxy resins produced under a certified mass balance system. The company previously received ISCC PLUS certification for its Duisburg, Germany facility, expanding its certified renewable feedstock offerings across Europe and North America.

ISCC PLUS is an internationally recognized certification system that supports traceability of bio-based, bio-circular and circular raw materials through a mass balance chain-of-custody approach. The certification is based on independent third-party audits and defined requirements for tracking sustainable inputs through the supply chain.

Powers noted that each new certification represents a step in Westlake Epoxy's strategy to integrate renewable carbon materials into its raw material supply chain while working to reduce energy consumption and greenhouse gas emissions.
