UPM introduces bio-based black pigment detectable in recycling sorting systems

FINLAND – UPM has launched UPM Circular Renewable Black, a bio-based pigment made from renewable lignin that allows black packaging to be detected by near-infrared (NIR) sorting technology used in recycling facilities.

Traditional carbon black pigments often prevent NIR detection, leading many black plastics to end up in waste instead of recycling streams. 

The new pigment provides a deep black color similar to fossil-based versions and works with current industrial processing methods.

According to a lifecycle assessment conducted under ISO 14040/44 standards and reviewed by DEKRA Assurance Services GmbH, the pigment has a verified cradle-to-gate carbon-negative footprint.

Raw materials come from forests certified by the Forest Stewardship Council and the Programme for the Endorsement of Forest Certification. 

The product also holds International Sustainability & Carbon Certification Plus for its chain of custody.

Production will take place at UPM’s biorefinery in Leuna, Germany, a facility with an investment of around US$1.52 billion that transforms sustainably harvested hardwood into biochemicals for various industries.

Robert Marx, commercial vice-president for UPM Biorefining, said the innovation combines deep black aesthetics with full recyclability and a carbon-negative profile.

In related developments, companies continue to advance recyclable packaging solutions. For instance, Mondi and Polana Bikes recently introduced paper-based reusable packaging for bike shipments. 

In Africa, Togo’s Rôbalôtô community initiative earned recognition for its plastic recycling model, while Yerecic Label obtained How2Recycle pre-qualification for certain PET label materials.
