MONTREAL, Sept. 13, 2023 /PRNewswire/ — 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 waste recycled plastics in Canada using Pyrowave technology. Tests carried out on the resulting elastomers demonstrated quality and intrinsic properties identical to those of elastomers manufactured from virgin materials of fossil origin.
Testing for future incorporation of recycled content in tires
Michelin, a key player in sustainable mobility, has produced a four-tonne prototype batch of styrene-butadiene rubber (SBR) at its plant in Bassens, France. SBR was produced using 100% recycled styrene by Pyrowave and has passed all quality tests with no differences compared to products made with fossil-based styrene. These tests are an important milestone for future testing incorporating Pyrowave recycled styrene into tires for laboratory and track applications to confirm performance evaluation.
More conclusive evidence for food packaging applications
Knauf Industries, one of the leading manufacturers of expanded polystyrene (EPS) packaging, technical parts and insulating products, can also generate expanded polystyrene parts using 100% recycled styrene produced using 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 from fossil styrene. Product safety was also validated through migration testing confirming compliance for use in food contact applications. This further demonstrates the viability of closed loop polystyrene using Pyrowave technology.
In both cases, the styrene used comes from recycled sources and the finished product (EPS or SBR) contains 100% recycled styrene content. Recycled styrene is present in the product, allowing for physical traceability.
This announcement is part of the collaboration project started in 2020 between Pyrowave and Michelin. Styrene has a lower carbon footprint than fossil styrene produced with around 82% less GHG reduction according to a recent life cycle analysis, and allows waste plastics to be used as raw material.
The tests carried out by Michelin and Knauf Industries respectively, incorporating recycled styrene, are significant, since 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 important opportunities with yields. identical to those of a virgin polymer.
The results of these tests are a true achievement for Pyrowave, as they demonstrate 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 customers. We are very satisfied with these results, as they portend a very positive future for new tangible applications of our technology,” said Jocelyn Doucet, President and CEO of Pyrowave.
