On 30 November 2021, the Government of Canada announced a CA $3.5 million investment via Sustainable Development Technology Canada (SDTC) to support Montréal-based Polystyvert—backing its transition from demonstration to full commercial-scale polystyrene recycling (Canada).
Polystyvert’s technology uses a solvent-based dissolution and purification system to separate EPS (and other polystyrene waste) from contaminants, then repolymerises it into food-grade resin. This funding builds on prior investment, enabling final development steps toward Canada’s first industrial-scale polystyrene recycling plant (Canada).
Technology and system design
- Solvent dissolution selectively purifies mixed EPS waste, including packaging and foodservice materials.
- Contaminants are filtered during separation and precipitation stages.
- The purified resin matches the quality of virgin EPS and ABS, enabling integration into existing downstream value chains .
- SDTC funding contributes to scaling the process from demo plant to full production facility.

Strategic relevance
The support reflects a clear policy intent: EPS, often excluded from curbside programs, can be reintegrated into circular systems when industry, technology, and government align. The funding:
- Accelerates the shift from pilot-project recycling to industrial implementation;
- Promotes food-grade recycled resin, confirming technical robustness;
- Demonstrates how public backing can accelerate private-sector circular innovation;
- Lays groundwork for future commercial plant activation in Canada (Canada, newswire.ca).
