Vice President of Goodwood Plastic Products says 80 per cent of plastics in HRM are recycled at their business

A Nova Scotia company is taking your plastics and turning them into plastic lumber.

The majority of plastics in HRM are being recycled at Goodwood Plastic Products according to Mike Chassie who is the Vice President of Goodwood, a company whose aim is to turn our plastic waste into something useful.

He tells NEWS 95.7 we need to find more responsible ways to deal with plastic.

"We're taking an item, plastic, and we're giving it a new life, it's being manufactured into a new product that in the right applications is going to outperform your traditional lumber products," says Chassie.

He enumerates the various benefits of plastic wood.

"It's more dense, it's pure plastic, there's no filler in it, so it does weigh more, but some of the trade off is it's not going to blow off your deck, and it'll last a lifetime," explains Chassie.

He says they are really trying to give plastic a new life.

"Plastic isn't going away anywhere anytime soon, there's always going to be plastic, and what we need to do is find more responsible ways to deal with it, and how we can manage it better at its end of life, or give it a new youth," says Chassie.

According to Chassie, 80 per cent of plastics in HRM are recycled at Goodwood Plastic Products.

Are plastic recycling programs rubbish?

Once an admirable goal for plastic packaging and single-use plastic products, recycling of late has been called “garbage” (New York Times Magazine), “greenwashing” (Greenbiz) and "The Great Recycling Con" (New York Times). In the latter article, authors Tala Schlossebers and Nayeema Raza call recycling “propaganda” because the industry “wants to trick us into thinking we can use as much plastic as we want so long as we recycle.”

Gee, Tala and Nayeema, tell us how you really feel about recycling!

Recycling seems to have hit a brick wall primarily because of problems associated with the incompatibility of various plastics. “Current plastic recycling and sustainability goals are limited by the intrinsic incompatibility of many polymers and the negative effect of fillers and impurities on end-product properties, thus requiring a high degree of expensive sorting, separating and cleaning,” Sal Monte, President of Kenrich Petrochemicals Inc. (Bayonne, NJ), told PlasticsToday. Another barrier is that the melt processing of polymers causes “chain scissoring,” resulting in recycle and regrind materials having inferior properties compared with virgin resins.

That is why sorting—a labor-intensive activity that results in a lot of waste—is necessary. Monte noted that the reason for separating #1 (PET) and #2 (HDPE) from #5 and #7 is because of the incompatibility between the materials, “unless you use titanium/aluminum additives that perform in situ catalysis of polymers and coupling of fillers,” he said. Using innovative additive technology that permits co-mingling of plastic materials into a single waste stream and deriving value from these materials to produce new products is the Holy Grail of recycling.

Monte said that current compatibilizers offered to recyclers are based on co-polymers or maleic anhydride (MAH) modified polymers. “Co-polymer compatibilizers require extensive sorting to match up the polarities of the recycled materials, and maleic anhydride often depolymerizes condensation polymers such as PET and nylon, obviating their use in post-consumer recycle,” explained Monte. “MAH technology claims to be a coupling agent, which is true for rebuilding polymer molecular weight, but it’s a misnomer when applied to coupling filler and organic interfaces.”

But the real problem is money, noted Monte. For recyclers, it’s unlikely that they will spend a penny more on additives to compatabilize co-mingled polymers. He said that sustainability goals such as a circular economy using curbside recyclate in new plastic parts are not achievable economically absent subsidization and legislation because of:

Shale oil—virgin is cheaper;

China’s National Sword—no market;

quality—Industry 4.0/automation;product liability litigation—specs must be met;

additives are expensive—recyclers will not add a penny to their material costs unless extensive and expensive on-site experimentation is allowed to demonstrate economic and technical efficacy;

curbside recyclers are not polymer chemists—it’s complicated.

Monte agrees with what I’ve written several times in my previous blogs. “Bulk recycling has pretty much been a confusing mess since it started,” he said.
