Holland Colours’ CircStab and LightGuard 400 successfully obtained RecyClass Technology Approval

Apeldoorn, September 16, 2025 – Holland Colours proudly announces that its additives HolcoPET CircStab (powered by EverCycle, trademark of SI group) and LightGuard 400 have successfully passed the RecyClass Recyclability Evaluation Protocol for PET bottles. This approval confirms their full compatibility with established PET bottle recycling processes. 

This recognition marks a key milestone in Holland Colours’ mission to deliver additive technologies that support performance and circularity. By meeting RecyClass’s stringent recyclability standards, CircStab and LightGuard now stand as proven enablers for high-quality rPET packaging. 

• HolcoPET CircStab stabilizes PET during recycling by preventing yellowing while preserving brightness and viscosity. 
• LightGuard 400 protects beverages, such as beer and juice, detergents, cosmetics, and other light-sensitive products by blocking the full range of UV light, while ensuring recyclability in PET streams.
