Walmart Canada's PET Subcommittee of The Material Optimization Committee, an Update

Posted by Chandler Slavin on Oct 16, 2012 5:24:00 PM

Greetings world!

We have made it through the BLIZZARD! Man oh man has it been crazy! The night of the storm the wind was swirling so fast you didn’t know from which direction it was coming! AND I witnessed “Thunder Snow,” which is basically a thunderstorm with snow instead of rain! Who knew!?! And my street, which is in the West Loop, just got paved TODAY so I have been stranded here since Tuesday! And the Metra trains, which I normally take to work, were super backed up and basically you couldn’t really get anywhere! It was sort of exciting…

Check out these pictures of Lake Shore Drive, which is a main artery of the city; at 8:00 on Tuesday they shut it down and all these cars were abandoned. Everyone was calling it a “Snowpocalypse!” Ha!

Anyway, for today’s post I thought I would give you an update on the progress of Walmart Canada’s PET Subcommittee of the Material Optimization Committee. For those of you who may be new to my blog, I was invited to be the co-lead of Walmart Canada’s PET Subcommittee in winter 2009, due to my research on recycling clamshells. To download the full research report, which draws on my involvement with this Committee, visit http://www.dordan.com/dordan_sustainability_research.shtml and select “Recycling Report.”

While the “goal” of the Committee was never really carved in stone, I was operating under the assumption that we were working towards achieving zero waste for PET packaging—bottle grade and thermoform grade—in the main Provinces of Canada. And while the approach too was a bit fuzzy, we investigated the plausibility of recycling PET bottles with PET thermoforms. The thinking was that because the PET bottle recycling infrastructure was so sophisticated, it may be easier to piggy back on it then create an entirely new recovery stream. Like the Starbuck’s cup recycling pilot that piggy-backed on the already established corrugate recycling stream, we hoped that if we could demonstrate to reclaimers that PET thermoforms do not contaminate the PET bottle recyclate stream, then we could begin integrating them into the existing PET recycling stream. After all, all the research I had done explained that there was nothing technically problematic about recycling PET bottles with thermoforms, just that it would be expensive to sort the PET thermoforms from other look-a-likes considered a contaminate to the PET bottle stream.

After several meetings, each member was assigned a task, which was “due” in by a specific date. I was instructed to summarize the APR’s Design for Recyclability Guidelines for PET bottles in hopes of using it as a template for creating Design for Recyclability Guidelines for PET thermoforms. After I submitted my summary, which you can find if you search my blog, I didn’t hear from my co-lead for several months. While I called him several times over the summer of 2010, it was conveyed to me that this project was put on the back-burner in favor of other, more important projects.

Yesterday my co-lead called me, however, to discuss the progress being made. This is what he had to say:

The Committee, which now seems entirely staffed by Walmarters, is making progress! The progress explained, however, does not seem that different than the progress reported by NAPCOR in our previous discussions. Like NAPCOR, my co-lead explained that after performing some pilots, it was found that it is easier to recycle PET thermoforms with PET thermoforms then within the PET bottle stream. The reason for this is multi-faceted, but in a nut shell, it is because no one wants to contaminate the PET bottle stream. Therefore, it is easier the develop processes and technologies for recycling PET thermoforms together then figure out what about them is problematic for the bottle stream. After all, a lot of time and investment has been made into the PET bottle recycling stream, thanks to NAPCOR and others, so trying to introduce a new packaging type into this system would probably do more harm than good.

Next it was articulated that for some reason, PET thermoforms manufactured in South America turned the PET recyclate fluorescent, which was making the reprocessing of the thermoform-grade RPET problematic. They are currently investigating why that is…

Lastly, it was reported that some type of adhesive on labels intended for food packaging is tinting the RPET beige during the process of recycling. Apparently Walmart is working with a Label Association trying to figure out what type of adhesive on these labels is contaminating the stream; once known, it was reported that Walmart will begin drafting suggestions for their suppliers in the context of sourcing labels for thermoform food packaging containers.

That’s all for today folks!

See you soon!

Happy Friday! This Saturday is my sister’s bachelorette party at Cuvee in Chicago, which is a super posh champagne lounge. I will let you know if I see any celebrities!

So I FINALLY finished my work on PET recycling for a Canadian retailer, which is good, as I leave on Tuesday!

Check it out! It’s sort of a lot, and it’s really detailed, so sorry if I bore you! Oh, and it’s broken into a couple different sections:
    1. Summary of a super huge document titled, “Best Practices and Industry Standards in PET Recycling.”
    2. Supply and demand of PET bottles post consumer, North American context.
    3. Supply and demand of PET thermoforms post consumer, North American context.
    4. Interview with StewardEdge and Stewardship Ontario’s Plastics Market Developer.
    5. Case studies of PET recycling, bottle to bottle, bottle to thermo, and thermo to bottle.
Seriously, this is the post of all posts! And when I copied and pasted my report into the Blog software, it messed up my outline--sorry!

All sorts of stuff

Posted by Chandler Slavin on Oct 16, 2012 11:01:00 AM

For those of you who have been following my blog, you are aware that our clamshell recycling initiative has sort of come to a stand still:

We determined why PET thermoforms are not recycled (lack of investment in the infrastructure due to quantity, quality, supply and demand issues) and the problems with including RPET thermoforms in PET bottle bales (different IVs, melting points, fear of contamination, etc.) While we did determine that our RPET clams and PET bottles are “read” the same via an optical sorter, when the mixed bales of RPET thermos and PET bottles make it to the processor, the thermos are thrown out and not recycled along with the PET bottles.

Consider the following article published in PlasticsNews, which does an amazing job summarizing all my research to date:

NAPCOR puts thermoformed PET on docket

By Mike Verespej

Posted May 24, 2010

Although blow molded PET and high density polyethylene bottles get most of the plastics recycling attention, a potentially large market looms on the horizon, presenting an opportunity and a challenge for the recycling industry — thermoformed PET containers.

In 2008, 1.4 billion pounds of thermoformed PET packaging was produced in the U.S and Canada. But by 2011, that market could grow to be one-half the size of the PET bottle market, which is the largest category of recycled plastic resin, said Mike Schedler, technical director for the National Association for PET Container Resources in Sonoma, Calif.

“The market is growing rapidly because of natural growth and conversion of products from polystyrene and PVC,” said NAPCOR’s Schedler.

But growth in thermoformed PET packaging and pent-up demand for recycled PET in those packages doesn’t automatically translate into a waste stream that can be turned into an end-market opportunity, he said. “The market is not the issue. The issue is moving it through the reclamation system.”

For the past 18 months, NAPCOR’s Thermoforming Council has been working with recyclers and material recovery facilities in the U.S. and Canada to address an array of technical issues, as well as difficulties presented by a huge variety of sizes and shapes of clamshells, boxes, trays, cups and lids.

Schedler said the council has three main objectives in regard to thermoformed PET.

“We have to remove the obstacles and create an infrastructure that will give PET thermoformed packages the same recycling opportunities as PET bottles,” he said. “And we have to do it in a way that is acceptable to existing collection systems and processes, and without jeopardizing the PET bottle recycling stream.”

Last, he said, “We have to support PET packages and do the things we did in the late 1980s to facilitate recycling of PET bottles.”

The council also is conducting a thermoformed packaging compatibility study to evaluate different streams of packaging and how well they meet industry protocols for fiber, sheet and bottles applications that have been developed by the Washington-based Association of Postconsumer Plastic Recyclers.

Specifically, the study is looking at dedicated thermoformed packaging bales manually removed from MRFs without auto-sort capabilities, mixed bales of PET bottles and PET thermoformed packages at MRFs with auto-sorting equipment, and mixed rigid plastic bales.

“We will convey that data and our observations to PET reclaimers,” Schedler said.

A fourth possible stream — cups from arenas and stadiums with PET recycling programs — will be addressed later.

“I could see separate recycling programs within stadiums for cups, and, to a certain degree, clamshells,” he said. “But I don’t see that happening at MRFs with auto-sort equipment.”

The industry is working to overcome technical hurdles that currently keep thermoformed PET packages from being recycled in tandem with bottles. Among them:

* Look-alike plastics like oriented polystyrene, polylactic acid and PVC containers that are difficult to sort from thermoformed PET packaging, either manually or in auto-sorting operations.

* Adhesives used on pressure-sensitive paper labels are different from those used on PET bottles and could cause yellowing.

* Some direct printing.

* Different additives than in PET bottles.

* Flake geometry concerns.

* Wide variability in intrinsic viscosity.

“We understand what it takes to do this work and we are rolling up our sleeves to do it,” Schedler said. “We want to make PET thermoformed packaging recycling a reality and to position PET as the environmentally preferred package of choice.”

In my last post, I discussed a company that is going to buy balled PET bottles and PET/RPET thermoforms from MRFs for reprocessing into the next generation of thermoforms. While I obviously have some questions and concerns in regard to the logistics of this approach, I feel like this is a step in the right direction. However, I feel that for Dordan, and the plastics industry in general, it is important to work on the residential recycling infrastructure level, as that is what the consumer has access to and informs his/her understanding of the “sustainability” of a given material. That being said, while a closed-loop system is awesome and a direction we would like to move, I will be focusing more on integrating our packages into the American recycling infrastructure in general because I really think that would resonate with consumers and the larger public. Additionally, the work I am doing with Walmart-Canada works on the residential level, as opposed to the closed-loop system level. If they can figure out a way to recycle PET thermoforms with or in addition to PET bottles, then hopefully, so can we.

Today I had a phone interview with a contact from StewardEdge, which is an organization in Canada that has their hands in issues pertaining to extended producer responsibility. This contact, however, works with Stewardship Ontario to develop markets for plastic post consumer. Our conversation today ROCKED because not only did he confirm my understanding of recycling, but he provided validation that our approach is one of relevance and that our goals are represented by our Canadian neighbors. So I am not alone after all, hurray!

Anyway, he explained that unlike the States, that which is driving recycling in Canada is Stewardship Ontario, which is an organization like Fost Plus in Belguim, which takes money from industry to manage the cost of said industry’s packaging waste. In other words, because there is legislation on the books in Canada that REQUIRES producers to fund the recovery of their packaging post-consumer, organizations like Fost Plus in Belgium and Stewardship Ontario in Canada developed to help producers meet said requirements.

Let me back up. In 2002 Canada’s Waste Diversion Act mandated that industry has to pay for 50% of the net cost for municipalities to run their Blue Box program. The Blue Box program is similar to curb side recycling in the States; however, they encourage the recycling of a lot more materials than is encouraged in the States.

The “designated” material types accepted for recycling via the Blue Box Program are listed here:? http://www.stewardshipontario.ca/bluebox/pdf/materialcategories.pdf.

Anyway, Stewardship Ontario was set up specifically to collect that money from industry and give it to the municipalities to manage packaging waste.

There are different fees for different materials, depending on the ease of recovering said material post-consumer. In other words, the harder a package is to recycle or recover, the higher the associated fee will be.

The fees change every year; here’s the latest: http://www.stewardshipontario.ca/bluebox/fees/fees_rates.htm.

For example, if you sold a polystyrene container into the Canadian market, you would be required to pay 24.65 cents per kg. These are real costs that affect the entire supply chain. PS is expensive because it is so lightweight (EPS is 98% air, 2% resin) there is no economical way to collect it for reprossessing (think shipping…); that is why EPS is one of the materials of focus for the MOC, because economically it is impossible to recycle…

Wow have I rambled. Sorry for the all over nature of this post; I have a point, I swear!

Tune in Tuesday (sisters taking a vacation!!!) to figure out where I am going with this and what needs to happen in the States to integrate thermoforms into the existing recycling infrastructure.

Tootles!
