Day 19: Nov. 5th, 2009

February 24, 2010

That Monday I arrived to the office more motivated than when I had left; how can I find a way to recycle clamshell—and more specifically—thermoformed, packaging?

As I waited for feedback from the SPC in regard to what they thought about the feasibility of finding an end market for non-beverage PET flake, the phone rang, and the receptionist transferred the call to my fine cubicle.

“Jessica with Waste Management is on line one,” she announced.

I picked up the line.

           …five minutes later….

Jessica was super cool; she is Dordan’s contact at Waste Management who manages our waste and recycling contracts, and wanted to reach out to me because she knew I had been talking with various Waste Management employees about my initiative. And, she also provided another crumb: She suggested that I contact another Major Account Representative in IL to discuss the feasibility of my initiative; she provided his name and number.

I called him that day, eager for some direction.



            …ten minutes later…

Hurray! A bigger bread crumb!

Apparently, what a plastic cup manufacturer in the Midwest had recently done, and he encouraged us to do, was send off some of our RPET clamshells to a Waste Management Material Recovery Facility (MRF) to see if their optical sorting technology would “read” our material like it reads the material in PET bottles. If the sorting technology couldn’t tell the difference between our RPET and the PET used in beverage bottles, then the material is close enough to theoretically be integrated into PET-beverage bales. In other words: the material is the same, which makes sense, because our RPET is certified at a 70% post-consumer regrind concentration, which means 70% comes from PET-beverages and 30% comes from virgin PET resin, give or take. Basically, if we thermoform material made out of bottles, why wouldn’t our packages then be compatible with this optical sorting technology.

The Account Representative offered to run our samples through their optical sorting technology to see if the problem with recycling non-beverage PET is due to sorting capabilities. Great!

He forwarded me the address of the MRF.

That day, I grabbed 50 of our sample as they came off the machine. Still warm with the heat from being formed, I placed them in the mail to go out with today’s post.


I sent the Account Rep the following email, confirming shipment.


I just wanted to drop you a quick email letting you know that I sent out a box of 50 RPET clamshell samples to the address you provided for you to run through your optical sorting machine to see if they are compatible with the PET bottle material. If so, we can try and find an end market for our RPET clams, blisters, and thermoformed components.

Just out of curiosity, do you know where I can find information on who has optical sorting technology and where? Moreover, do you know who collects mixed plastic (that is, the plastic left over after the PET bottles have been removed) for material recovery and where?

Thanks again for all your help! I look forward to speaking with you again.



Tune in tomorrow to learn more about recycling in America.
