The Recycling Challenge

Putting More Materials in Ontario’s Blue Boxes

Ontario, the birthplace of the Blue Box, is perhaps one of the world’s most mature constituencies for stewardship and recycling behaviours. The Blue Box Program currently diverts from landfill close to 70 per cent of the six categories of printed paper and packaging materials that its industry stewards sell into the marketplace. Innovation is essential to stay ahead of the curve. The more materials Ontario households can put out for curbside collection, the more waste we divert from landfill. To do this efficiently, affordably and sustainably, we must encourage local processors to develop green technologies that will increase the volume of materials we can recycle, and the value of Ontario’s green economy.

The Environmental Chemistry

The Potential to Process Clear and Expanded Polystyrene

Kingston’s GreenCentre Canada brings together academic researchers and industry partners to develop and market clean, less energy-intensive alternatives to traditional chemical products and manufacturing processes. They needed help to prove that a green solvent solution they’d developed was viable, and Stewardship Ontario gave them a grant for lab testing and investigation.

The tests revealed that the green chemists’ Switchable Hydrophilicity Solvent (SHS) system had the potential to process clear and expanded polystyrene—especially those soiled food trays that can be covered in contaminants. Plus, after the cleaning or extraction process, SHS can be returned to its pure form without energy-hungry, expensive distillation, and can be harvested for reuse. When GreenCentre was looking for help commercializing the technology, we recognized the potential to revolutionize recycling capabilities in North America.iSt_1347298_MALELABTECH
