Clariant now offers a range of certified OK compost INDUSTRIAL pigments

To meet sustainability targets and fulfill commitments to achieving a more circular economy for plastics, plastics manufacturers are turning to the use of alternatives to the traditional fossil-based raw materials they have for decades relied on.

Clariant’s business unit Pigments is contributing to this transition with its offering of a range of certified OK compost INDUSTRIAL pigments, offering customers new coloring opportunities.

Nine selected products in Clariant’s PV Fast and Graphtol ranges have now earned the  OK compost INDUSTRIAL label, which certifies that these products meet the requirements of  European Union EN 13432: 2000 standard when not used above the maximum concentration in the final application.

“We are proud of this development that is part of our strategy to offer solutions for more sustainable packaging and to strengthen our product portfolio,” said Andreas Buder, Technical Marketing Manager Plastics at Clariant. “This certification allows our customers to use bright colors in their biodegradable products, since they are suitable for industrial composting.”

The PV Fast and Graphtol range of pigment powders are high performance organic pigments. Both product ranges are used in various applications in the consumer goods sector, such as sensitive food contact packaging, plastics tableware/dishware or toys.

The coloration of biodegradable polymers requires the pigments to meet certain characteristics in order to be considered compostable. For processing through organic recovery facilities, this requires a low heavy metal and fluorine content, and no ecotoxicity towards plants.
