Nine selected pigments from the PV Fast and Graphtol product lines of Clariant’s pigments ´óÏó´«Ã½ unit, now feature the label OK Compost Industrial that fully meet the requirements of the European Union EN 13432: 2000 standard when not used above the maximum concentration in the final application. The company sees this representing a significant contribution to the growth in compostable plastic articles.

The coloration of biodegradable plastics 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. 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.

Said Clariant’s technical marketing manager for plastics Andreas Buder,“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. This certification allows our customers to use bright colors in their biodegradable products, since they are suitable for industrial composting.”
