Introduction:
Even the most naïve person should know that almost all man-made product, in the world of plastics, metals, cardboard, and glass is by intent and definition, recyclable. Unfortunately, ninety percent of world plastics go un-recycled. In real life not everything will be recycled or is being recycled because of various causes, though the two main reasons:
- Local Municipalities lack the infrastructure to properly separate materials and recycle them accordingly with homogeneous materials to make new safe products,
- Some do not get recycled because of its nefarious consequences when leaching in the recycling process harmful chemicals into the new products when trying to achieve the so-called “new recyclable materials”. This process also contaminates the water being used to recycle, which then needs to go through a cleaning process in any wastewater facility. In fact, many recycling depots, do not even take certain plastics categorized as “recyclables” because they do not have the machinery and personnel to recycle them and if they do, their recycling costs would skyrocket making them unprofitable.
Having said the above, according to the Canadian Plastic Industry Association (CPIA), not all plastics are recyclable, but most plastics are. The blunt truth is that unfortunately, not every recyclable depot or facility (regardless if it is privately or government-owned) takes them or uses them in their recycling process. CPIA insists that they are “continuously expanding the range of possibilities to include those that aren’t recyclable today.”
Plastic Classification And Codes
Many other sites/sources have this exact same table. For a clearer image please visit: https://depositphotos.com/vector-images/resin-identification-code.html?qview=60922897
Recycling codes #1 (hard) and #2 are the most widely accepted.
They are becoming more commonly accepted as technology improves and as the market for these plastics grows. But not all places accept these plastics because they both leak strong chemicals during the recycling process.
It is difficult to recycle these plastics into other products. Or, in some cases, it is just not economically feasible to do so. These tend to contaminate the recycling stream so they need to be discarded with caution.
What Are Plastics?
Plastics are simply “chains of like molecules linked together. These chains are called polymers.” This is why many plastics begin with “poly,” such as polyethylene, polystyrene, and polypropylene.
What are Non–Biodegradable Fossil-Based Polymers?
The term non-biodegradable describes polymers that do not break down to a natural, environmentally safe condition over time by biological processes.
Important Note:
Something to always keep in mind is that bacteria do not attack or eat plastic. Therefore plastics do not tend to be biodegradable unless they are made with new recent technology and materials that are not yet cost-effective, but they are starting to show around more and more. This biodegradability of plastics can only be achieved when microorganisms in the environment break and metabolize the structure of these new biodegradable plastics. This has a positive impact on our landfill and overall environment but we are still far away to make them standard in our various industries.
Is The Canadian Recycling Program In Crisis?
Our recycling program with foreign countries is so inefficient and inaccurate, that thousands of containers are being returned to Canada from Philippines and Malaysia against our tax dollars, along with the serious restrictions imposed by China to the rest of the world (Canada included). Now the questions remain: What are we going to do with those containers full of “recyclable materials”. Easy, we will incinerate them (and push more CO2 into the atmosphere) or we will bury them in our constantly growing landfills. But I guess to some that is only an illusion because our pride does not allow us to see and accept our deficiencies, eh?! Yes, I am being a bit sarcastic, but let us face it, if we do not see and accept our weaknesses and mistakes, we will never implement a positive search for a viable and efficient solution. That by itself is the danger we have to avoid so we can still be an example to other countries that make an effort to emulate us.

Not too long ago, China decided to close its doors to various types of plastics from all around the world. Since then Canada has been in a difficult position, not knowing what to do with all its plastic, which is currently being accumulated in various landfills across the country.
There was an article published by the Globe and Mail last May 15, 2019, in which one of the main messages are:
“A recent study by Deloitte for Environment and Climate Change Canada shows there is much room for improvement: Only 9 percent of the 3.2 million tonnes of plastic waste generated each year in Canada are recycled. As much as 2.8-million tonnes – the weight of 24 CN Towers – ends up in Canadian landfills.
After 30 years of recycling programs that force residents to collect, wash and fill blue boxes with plastic bottles, bags, and containers, it turns out that in 2016 more than 3.2 million metric tonnes ended up as garbage, according to the summary of a report produced by Deloitte for Environment and Climate Change Canada.
Of that amount, 86 percent went to landfill, 4 percent to incinerators and 1 percent — 29,000 metric tonnes — ended up as litter which can contaminate lakes and oceans. Most of the wasted plastic comes from offices, institutions or industries.”
This is a “come-to-Jesus moment,” says Jo-Anne St. Godard, executive director of the Recycling Council of Ontario. “We’re going to have to shine a light on those materials that we’ve been sort of hoping would get recycled but, really, at the end of the day, aren’t.”
