Hello world!
So Canada is awesome. Toronto has the most amazing waste management system EVER. Check it:
You have to pay depending on the size of your garbage can; the bigger the can, the more you pay.
The result: tiny garbage cans and huge recycling bins.
Monetary incentive facilitating public action? I think so!
AND they have a bin for organic waste.
AND they provide bags for “electronic waste.”
So, unlike me, who, upon discovering a facility in the far South side of Chicago accepted electronic waste, drove around and around trying to locate said facility, local Torontonians simply place their e-waste in the wonderfully provided designated bag. What a life!
So yeah, it was really cool to see how waste is managed in Canada, which has some EPR legislation in place. I don’t know who is making money, if any, off the system (usually costs municipalities money to recycle), but something is definitely working right…
Here is what I learned; get excited!
It is in fact very possible to recycle PET thermoforms and bottles TOGETHER!!!!! So, all those who articulated reasons why the two packaging types were incompatible for remanufacturing together (i.e. different IVs, melting temps, molecular length, etc.) were misinformed! Hurray! And the clamshell recycling initiative rises from its grave!
This is positively wonderful news. If we can recycle PET thermoforms with PET bottles, than the value of the recyclate will remain higher than if PET thermoforms were recycled with other plastic materials, thereby constituting a low-grade plastic mix. From what I understand, bottle-grade PET is the highest grade, or enjoys the most inherent value. If PET thermoforms are made out of bottle-grade PET like ours are (supplier-certified 100% PCR PET), then they TOTALLY can be baled with PET bottles and sold together for remanufacturing into any of the following: new RPET bottles (more expensive reprocessing, need to clean resin for FDA-certified food compliance), new RPET thermoforms, any polyester-based fiber application, plastic strapping, and a TON of other products.
AND I spoke with a gentleman that runs a MRF and he concluded that they do collect and bale PET bottles and PET thermoforms together for market. AWSOME.
I wonder how much of these mixed PET bales are generated…
I wonder what the specs of the mixed bales are…
However, a working industry group recently conducted a pilot to test the integrity of these mixed bottle and thermoform bales and concluded that the adhesives used on labels on PET thermoforms compromised the recycled material. While I am a little hazy on the details, it was reported that the recycled material was unacceptable for market because of the adhesives, which are considered a “contaminant” to the overall integrity of the recyclate. Soooooooo I guess what this means is that:
- PET bottles and clamshells can be recycled together; yippee!
- Packaging suppliers need to begin to design thermoform PET packaging “for recycling.” While the APR has guidelines for designing bottles for recycling, no guidelines exist for designing thermoforms for recycling. Such guidelines could suggest things like:
- The adhesive used for binding labels and other marketing information to PET thermoforms needs to be X or can’t be Y or something to that effect.
I am looking forward to learning more about the results of this pilot; it is just so cool that people are interested in this, too. And here I thought I was all alone…
After speaking with another gentleman who knew a thing or two about a thing or two, I understand the current climate of recycling in North America to be as follows:
There is a HUGE demand for PET recyclate from bottlers, brand owners, and CPGs; however, there is not enough SUPPLY due to limited collection. This supply and demand disproportion can be solved, perhaps, by implementing the following actions:
- Implement bottle deposit programs/legislation—this would provide consumers with an economic incentive to recycle their PET bottles.
- Incorporate PET thermoform packages into the PET bottle recycling infrastructure. I like this one.
- Limit the amount of PET bales that are exported each year.
The ACC estimates that 400 million pounds of a particular plastic needs to be generated in order for the recycling of it to be profitable. According to Plasticstoday.com, 1.4 billion lbs of PET thermoforms were generated in North America in 2008. This implies that PET thermoform bales could constitute a recycling steam all on their own, without piggy-backing on PET bottles. However, perhaps it’s easier to integrate them into the existing PET bottle recycling infrastructure than create a new stream of PCR PET, thermoform grade? Now I just don’t know…
Tomorrow is my birthday and this Saturday is my sister’s wedding! Therefore, I will be unbloggable until early next week. But stay tuned, there is a ton of interesting stuff I need to report to you!
