resins to be introduced with mechanically recycled content for potential use in interior and exterior automotive applications. They also may comple- ment other types of sustainable materials, such as certified renewable products from bio-based content, which are also being developed. SABIC T2E-3320EH PP compound features
stiffness, low emissions and high heat resistance for non-visible heating/ventilation/air conditioning (HVAC) components within the instrument panel and interior and under-the-hood parts. Xenoy T2NX2500UV resin contains 21% recycled PET. It provides good heat and impact performance, dimensional stability and low shrinkage for painted exterior body panels, spoilers, fuel filler doors and trim. It is also UV stabilised for potential use in unpainted applications. Xenoy T2NX5230 resin contains 16% mineral reinforcement and 29% recycled PET. It is also a potential solution for painted body panels, trim and other components. The product’s reinforcement delivers higher stiffness and a lower coefficient of linear thermal expansion (CLTE) compared to Xenoy T2NX- 2500UV resin, making Xenoy T2NX5230 resin a good candidate for roof spoilers and exterior trim. Both Xenoy grades offer high flow for improved throughput, says the company. SABIC has also launched a certified circular PC
resin and blends made from the upcycling of post-consumer mixed plastic. According to an internal SABIC LCA study, the certified circular PC offers a potential carbon footprint reduction up to 23% in comparison to its incumbent. The PC Lexan
resins are suitable for applications in E&E, automo- tive, healthcare and consumer goods. The company is also collaborating on the
Microsoft Ocean Plastic Mouse, with an exterior shell containing 20% recycled ocean plastic, which is defined as plastic that has been certified by a third party as recovered from any ocean or ocean- feeding waterways or where it washed ashore from these locations.
Packaging and more Borealis and Reclay Group have joined forces to satisfy increasing market demand for the supply of recyclate material for use in high-end plastic applications. The partnership will optimise the recycling value chain, starting with Germany, one of the largest European recycling markets. The new agreement provides Borealis with access to a secure and steady supply of feedstock in the form of lightweight packaging waste collected by Reclay’s Extended Producer Responsibility scheme in Germany. The plastic packaging waste is then processed at Borealis’ own recycling plants, extending the range of applications for which recycled plastics can be used. Borealis has also partnered with Swiss dairy company Emmi and Greiner Packaging to create the first chemically recycled PP ready-to-drink iced coffee cups. Chemical recycling renews plastic to form recycled materials with a level of purity equivalent to fossil-fuel based PP, for protective, food-safe and other demanding applications. In this way, Emmi is utilising difficult to recycle
Recycled PVC compounds for shoe soles
In recent months, European com- pounder Benvic has been integrating a number of recycling competencies in-house, mainly via its subsidiary Ereplast which it acquired in 2019 and, in particular, relating to the company’s core expertise in PVC and PVC compounds. When Benvic integrated a range of TPE compounds into the company during 2021 it gained a foothold in the market for shoe soles which is also a significant consumer of PVC – the soles of which are processed by injection moulding. Benvic says PVC recyclate is
currently better valued than 100% virgin PVC and so commercial factors make injection moulded shoe soles in

PVC containing recyclate more economically viable. “However, technical constraints can appear,” the company says. “The choice of colours, for example, is highly dependent on the types of incoming recyclate. Indeed, light colours can only be addressed with transparent recycled products, which also has an impact on the design of the shoe as well as on the availability. Fortunately, Benvic is in a position to propose and create solutions across the colour spectrum.” Benvic says it is developing new
materials with higher added value, and this requires an exacting tailor- made approach for customers, both for the recycling and formulation part.
This is a new challenge because it concerns PVC recyclates that are intended for injection moulding and not for extrusion. The company says it is helping
create a truly circular economy by directly engaging with the producers of footwear. For example, it is part of a circularity scheme which allows the company to treat the used soles after collection, in order to produce a new compound, either resold to the producer or sold into the market. Other circularity schemes are also being developed for multi-product partners, allowing the recycling of flexible PVC from other returned products into shoe soles.
