Clariant pigments certified for use in compostable plastic

Clariant certified pigments can be used to color plastic products, including packaging, intended to be compostable.   

 

Nine selected products in Clariant’s PV Fast and Graphtol ranges now feature the label OK compost Industrial, that fully meets the requirements of the 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 organic pigments. Both product ranges are used in several applications in the consumer goods sector such as sensitive food contact packaging, plastics tableware/dishware or toys. Label opens new color opportunities to masterbatch and packaging producers and helps the fast-moving consumer goods (FMCG) industry fulfill its sustainability commitments.  

 

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