New black colorants: Polyone support circular economy turn former waste recyclable packaging
OnColor™ Infrared Sortable Black for Recyclable Packaging contain no carbon black pigment, permitting the automatic optical sorting sensors used in many waste management plants to detect black polymers and sort waste into the correct recycling streams.
Detection and sorting of carbon black-filled plastic waste in material recovery facilities is a vexing issue for the packaging and recycling industries, because the equipment relies on the reflectance of near infrared (NIR) wavelengths. Carbon black makes it impossible for the equipment to identify the waste, which must then be sent to landfill or incineration.
PolyOne’s new black colorants address this issue by eliminating carbon black and enabling black plastics to be sensed, sorted, and recycled efficiently. They can also help brand owners to retain current black packaging that was deemed unrecyclable.
OnColor™ Infrared Sortable Blacks for Recyclable Packaging is available in both liquid and solid form in a range of eight black shades as well as custom colors. Additional information about this collection can be found here.
These colorants are the latest addition to PolyOne’s robust sustainability portfolio that supports improved recyclability and the goal of a Circular Economy.
