US compounder and distributor PolyOne (Akron, Ohio; www.polyone.com) has achieved “OK Compost” (www.okcompost.be) certification by Belgium’s AIB-Vinçotte (Vilvoorde; www.aib-vincotte.com) international certification institute for its “OnColor” bio and “OnCap” bio masterbatches. The company says this is the first time the approval has been awarded to a full range of colorants and additives.

“As environmentally conscious consumers become more aware of the 'OK Compost' certification, demand is growing for packaging and consumer goods that earn this label,” said Marcel Dartée, PolyOne’s global marketing director for biopolymers. “Using our exclusively certified colorants and additives helps customers to accelerate 'OK Compost' approval of their products. In addition, PolyOne is able to formulate application-specific solutions that are certified in advance.”

Packaging or products featuring the "OK compost" label are guaranteed as biodegradable in an industrial composting plant. This applies to all components, inks and additives.
