Recycling systems the packaging supply chain can enable black plastic packaging to be recycled into a high quality, high value material. The latter can be used as a substitute for virgin plastic in the manufacture of new items, and benefit the environment as well as the financial viability of mixed plastics recycling. WRAP’s work in partnership with key players in the retail supply chain was carried out in three phases, including the use of alternative sorting technologies and alternative colouration systems, as among the potential solutions. Novel NIR (near-infrared) detectable black colourants were developed and shown to look satisfactory in amorphous PET (APET), crystallised PET (CPET), PE and PP packaging food trays. Thus, the packaging can be sorted by polymers using NIR sorting systems used commercially in plastics recycling. WRAP said that the incremental costs of using detectable black colourants are anticipated to be reduced over time as demand and volume increases. In a related development, UK gourmet dairy brand The Collective is introducing a NIR colourant technology that could help the industry recycle black plastic trays and packaging. The original Collective lid featured carbon black and other pigments, which are not detectable to the sensors used by recycling operations.

Yoghurt tubs feature the new NIR colourant technology
Collective consulted with UK-based independent consultancy in recycling plastics solutions Nextek and partnered with specialist additive and masterbatch manufacturer Colour Tone to develop a new black masterbatch. Thus, from now, the black lids on The Collective’s 450 g and 900 g yoghurt tubs will feature the new technology. On the recycling technology front, US equipment manufacturing and engineering company National Recovery Technologies (NRT) has integrated its SpydIR optical sorter with Max-AI technology, an artificial intelligence system that identifies recyclables and other items for recovery using a camera and neural network algorithm (NN). NRT’s SpydIR technology uses NIR detection to identify plastics, paper, wood and other materials by material type. Now, with the Max-AI optical sorter, it employs both detection technologies to create an optical sorter that is able to combine the information from each technology to deliver a unique sorting capability.
