First Finished Products Made With Recycled Styrene Generated Through Pyrowave Technology

Montreal, September 13, 2023 — Pyrowave, a Canadian technology company, is proud to announce that Michelin and Knauf Industries have successfully produced batches of finished elastomer and plastic products incorporating 100% styrene from plastic waste recycled in Canada using Pyrowave technology. The tests performed on the resulting elastomers demonstrated quality and intrinsic properties identical to those of elastomers made from virgin fossil-sourced materials.

Tests for Future Incorporation of Recycled Content in Tires

Michelin, a key player in sustainable mobility, has produced a four-ton prototype batch of styrene-butadiene rubber (SBR) in their Bassens plant in France. The SBR was produced using 100% styrene recycled by Pyrowave and has passed all quality tests with no difference compared with products made from styrene of fossil origin. These tests are an important milestone for further tests incorporating Pyrowave recycled styrene in tires for laboratory and track applications to confirm the performance evaluation.

Further Conclusive Tests for Food Packaging Applications

Knauf Industries, a major player in expanded polystyrene (EPS) packaging, technical parts and insulation products, can also generate expanded polystyrene parts using 100% recycled styrene produced through Pyrowave technology, in this case from the collection operated by Knauf Circular® in France. The resulting products passed all laboratory tests for performance and quality equivalent to products made with fossil styrene. Product safety was also validated through migration tests confirming compliance for use in food contact applications. This further demonstrates the feasibility of closed-loop polystyrene using Pyrowave technology. In both cases, the styrene used originates from recycled sources, and the finished product (EPS or SBR) contains a 100% recycled styrene content. The recycled styrene is present in the product, therefore enabling physical traceability.

This announcement is part of the collaborative project initiated in 2020 between Pyrowave and Michelin. Styrene has a lower carbon footprint than fossil styrene produced with a reduction of around 82% less GHGs according to a recent life-cycle analysis, and allows waste plastics to be used as a raw material.

The tests performed by Michelin and Knauf Industries respectively, incorporating recycled styrene, are significant as SBR and EPS are technical polymers used in the industry. Since SBR and EPS production processes are relatively sensitive to contamination, the success of these tests demonstrates the reliability of Pyrowave technology and that the recycled styrene produced can replace fossil styrene in technical applications, thus offering sizeable opportunities with performances identical to those of a virgin polymer.

The results of these tests are a real achievement for Pyrowave, demonstrating in prototype conditions the preservation of product quality while reducing the environmental footprint.

“The results of these tests confirm what we already knew, namely that recycled products with innovative technologies can meet the highest quality requirements for our clients. We are extremely pleased with these results, as they foreshadow a very positive future for new tangible applications of our technology”, stated Jocelyn Doucet, President and CEO of Pyrowave.
