Clariant additives enable recyclability of plastic waste without sacrificing material’s valuable properties

Clariant Circle designationComplementing its “fit for reuse” solutions that Clariant (Muttenz, Switzerland) announced on Aug. 21, when it demonstrated how its additives are recyclable, Clariant now showcases the next level of the technology at K 2019 (stand J 11, hall 8A). The company is shining the spotlight on how its additives can make it easier to recycle post-production and post-consumer plastic waste while retaining the material’s performance properties.

Newly developed AddWorks PKG 906 Circle for polyolefin film is a prime example of enabling plastic packaging producers to achieve some of their critical sustainability and business goals, said Clariant. Those goals include waste reduction, less consumption of virgin resin, lower costs and increased production efficiency. The addition of this polymer stabilizer allows producers to significantly increase the reuse of waste materials in their polypropylene (PP) and polyethylene (PE) films, recycling their own reground scrap without any loss of performance or processing efficiency.

It is particularly suited for biaxially-oriented polypropylene (BOPP) manufacturing but is also applicable to cast and blown film processes, noted the company in its announcement. With Clariant’s additive, the reuse content of post-production waste in the final film can be increased by as much as 30%. At the same time, the additive is proven to protect the resin so that film quality remains excellent with significant reduction of gel formation and prevention of additional yellowing at the same high line speeds, according to the company. 

AddWorks PKG 906 is the first Clariant product to carry the “Circle” designation, which was introduced to highlight products and solutions that have been specifically designed to deliver significant benefits to the re-use or recycle process. 

“Three hundred million tons of plastic waste are generated every year and only 2% are effectively recycled,” commented Stephan Lynen, Head of BU Additives, Clariant. “Closing the loop for plastics starts with designing materials that are easier and economically efficient to recycle. Our additives can help to increase recycling yields, and avoid degradation, odor and discoloration. We will continue to develop additives that increase the reuse potential of industrial and consumer waste. Our commitment is without alternative.”
