Dordan's Story to Sustainability...any takers?

Posted by Chandler Slavin on Oct 16, 2012 2:57:00 PM

Greetings!

I know I said I was going to have a juicy email for you today about all things composting BUT I just got done with Dodan’s “Story to Sustainability,” which I wish to share with you. I intend on submitting it to some of my colleagues in the publishing world to see if it would resonate with their readers/subscribers; if so, perhaps we could get some coverage. Let’s say HURRAY for free press!

Granted it is a little cheesy and I definitely tout my own horn a bit, I think it still helps to convey our understanding of sustainability, which sets us aside from our competition.

The part that gets good is after the “this brings us up to present day” section because it discusses how “sustainability” for us is an ever-evolving concept that draws on much more than marketing claims but an integrated approach to a constructed ethos. Sounds heady, huh?

Enjoy!

Happy day!

Happy Day!

I am writing you all from the luxury of my rooftop deck, where the sun’s rays are turning my skin a healthy shade of sun kissed! Not to rub it in our anything…

Today I am working from home, which I love (can’t you see why!). This morning I went to DePaul University to get my “Alumni card,” which grants me access to all the DePaul library’s databases, archives, journals, etc. I got to take a new picture and everything; I am giving the thumbs up sign and I have a very enthusiastic expression that just screams alumni. YAY for research!!!

After that I had lunch with my most favorite professor from my undergrad. He is an ethicist and, working in the world of sustainability, I see a lot of overlay between our two worlds. After all, ethics are just the discussion of value systems, of which, the “green consumer” enjoys its own space. He is actually teaching a class on environmental ethics and said he would provide some insight!!!

I just got done writing a marathon of an email to Dordan’s web designer. Now that we have a whole new sustainability initiative i.e. zero-waste, we need to restructure the sustainability information displayed on our site. I’m thinking of breaking Dordan’s sustainability efforts into the following categories, social and environmental, and plugging away from there. I hope this restricting doesn’t cost a million dollars…

I have been emailing everyone I know who knows anything about composting, trying to figure out the best one to buy for Dordan’s food and yard waste generation. I am actually getting a lot of really good feedback, which I will share with you all after the Holiday weekend. I will also be announcing which composter we are going with; exciting!!!

Well, I know today’s post was super lame because I just talked about myself but what can I say, I left all my research at the office!

Now I am off to describe our sustainability efforts for distribution to various editors to see if they would be interested in running a story on us; it certainly would be a cute one, in my opinion.

I am taking a vaca day tomorrow so I will resume blogging on Tuesday of next week. I hope everyone has a wonderful Holiday weekend!!!

Your packaging and sustainability friend,

Chandler

Let's recap, some misc. tid bits

Posted by Chandler Slavin on Oct 16, 2012 2:55:00 PM

Hello and happy new month! I have to say, I think July is my second favorite month after June, which I have an affinity for because it is the month I was born!

I know I have been slacking on my daily posts—I apologize. I have a lot of catching up to do after the Holiday and I am up to my ears in information about composters. I will have a really good blog post for you about composting soon; think of it as business composting 101, per se, but I have not finished my research quite yet so I don’t want to jump the gun…

Speaking of guns, I got to fire my first “riffle” this past weekend; granted I fired it at a target that I apparently did not even come close to, it was still fun, although the “kick back” was almost enough to kill me. So that’s how I spent my Holiday—in a farm in the middle of nowhere, driving tractors and shooting guns. Well, only one gun.

Okay wow really off target, Chandler (no pun intended). I am beginning to have way too much fun with this blog.

Let’s recap: Work on recycling PET thermoforms is moving at the pace that the Committee I am co-leading is moving; that is, slowly. If it helps put the pace of work in perspective, I sent out my notes from the last Committee meeting to my co-lead who forwarded them to legal four weeks ago; we still have not heard back from legal…

I will readdress these issues in a week or two; in the meantime, I am focusing on Dordan’s action plan for its goal of achieving zero-waste. In doing so I am now completely restructuring our website to house these new sustainability efforts. Once I get the website changes finalized and reach out to different publishers who may be interested in covering our sustainability story, I will aggressively design our action plan; I assume this will be way more difficult than I am anticipating as we have several hard-to-place materials, like the corrugated tubs inside the rolls of plastic we buy…

Also, for all those creative folk out there, we are brainstorming on a brand for our new sustainability efforts. As discussed in a previous post, most of my work on sustainability thus far has been from a macro- level. What I mean by this is I was focusing on the sustainability of different packaging materials in general, waste management of packaging materials in general, plastics’ reputation in general, etc. (think my rebuttal to The NYT’s The Haggler: http://plasticsnews.com/headlines2.html?id=17268&q=chandler+slavin). Now that we are actively pursuing our own intitaives, we need to brand said efforts. A lot of companies out there have their own “green team” or what not, which overseas all the sustainability works. We need some kind of green team, too. Well, we don’t need the team; we just need the brand. Get it? Again, our new sustainability initiatives are social and environmental: social insofar as I will be doing grassroots education about recycling with schools and we will be donating the food from our Victory Garden to local charities and events; and environmental insofar as we are working towards zero-waste and trying to recycle thermoforms. If anyone comes up with a brilliant idea you will win a fabulous prize, like oh I don’t know…research about recycling! Fun fun!

OKKKKKKK and for the meat of today’s post: I am happy to report that the Sustainable Packaging Coalition, in partner with Metaphore, just created an awesome new website, which discusses the life cycle of paper. Check it out: http://www.thepaperlifecycle.org/.

I really like this website because it is pretty and brings to light a lot of issues about sourcing paper that people don’t often recognize such as deforestation, exports, illegal logging, etc. Again, kudos to all those involved!

Also, I was really tickled pink with today’s Chicago Tribune article titled, “Green Choices.” Unlike most coverage of “sustainability,” author Monica Eng did a splendid job highlighting the pros and cons of different materials and situations. No reductionstic stances here! Check it out: http://www.chicagotribune.com/health/ct-met-eco-questions-20100706,0,3618266.story.

I gotta find this Monica…I am a big fan!

That’s all for today my wonderful packaging and sustainability friends. Again, I apologize for the “light” content of today’s and the previous days’ post. I promise I will bring the bull back; in the meantime, go packaging!

Tootles!

Plastics News, The Plastics Blog shout out!

Posted by Chandler Slavin on Oct 16, 2012 2:53:00 PM

Hey guys!

Oh man I have so much fun stuff to do so I won't be able to really post today.

That being said, check out my shout out in Plastics News' , The Plastics Blog:

One processor's thoughts on bioplastics

By Don Loepp on June 14, 2010 1:27 PM ET | 1 Comment | No TrackBacks

Bioplastics are a hot topic among recyclers -- especially biodegradable resins. Are processors paying attention?

Dordan Manufacturing Co. Inc., a thermoformer in Woodstock, Ill., has been studying the issue for some time, and today Chandler Slavin, the company's sustainability coordinator, posted a thoughtful item on the topic.

"Bio-based plastics, environmental considerations," on GreenerPackage.com, compares bioplastics like PLA to conventional resins like PET."Taken together, one would assume that the 2005 Ingeo PLA is a more sustainable option than traditional plastics, as manifest through this study," she concludes. "However, it is important to take into account the other dimensions discussed above, such as end of life management, complete biodegradation, and sustainable sourcing. By understanding the advantages and disadvantages of bio-based resins from an environmental perspective, packaging professionals can make informed material selections and truly comprehend the ecological ramifications of their packaging selections and designs."

It's nice to see a processor taking the time to do the research into the pros and cons of using bioplastics, and I know that Dordan isn't alone. I get a few phone calls a month from processors with questions about what materials are "most sustainable," and I know others at Plastics News get the same question.

As I wrote back in January, I think most processors are willing and able to adapt to their customers' materials-related sustainability goals -- they just need information and guidance.Processors are flexible about using recycled content, or bio-based resins, or switching from one virgin material to another. It all depends on cost, performance and what the customer wants.?

Great post. It's amazing the turn around in interest concerning environmentally alternatives from just a few years ago. While environmentalists cheer the effort, the true story lies in the market, which has demanded these materials and changes. The big question always was "do people want it"? As of 2010, it looks like they want more choices concerning recycling, sustainability, and how best to take care of the planet.?

Hello world!

I leave tomorrow for Canada to work with a retailer in hopes of facilitating their goal of zero waste for PET packaging post-consumer. And guess what: We are meeting at a company that supposedly buys PET bottles and thermos post-consumer and converts them into new packaging!!! Cool beans!

Therefore, all the questions I had about “Company X” (May 24th post), I can now ask this company!!!

Wish me luck!

Happy Monday Funday!

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

Happy Monday Funday!

The company that I made the “Sustainability and Packaging” presentation for, which I posted to my blog on Friday, sent me the following email after receiving said powerpoint (I sent it early for confirmation of its content):

“180 slides is way too long, even for a medical convention…”

Ha!

How do you provide an “overview of sustainability” in 60 slides, which is what this company suggested? I guess I am just as dilligent a powerpointer as I was a student; I was one of the special few who had to speak with my professors about exceeding the page limits for term papers—old habits die hard…

Anyway, tomorrow’s the day: My big presentation for a giant company on all things “Sustainable.” I am going to wear my new power business suit and fab heels AND I took my face piercing out several weeks ago so I look totally business-like.

For today’s post I thought I would reflect on a recent happening in our industry, which was convered on greenerpackage.com, PlasticsNews, and other misc. packaging publications. Because the company in question is a competitor, my superior was hesitant about me articulating my questions in a public forum i.e. on greenerpackage.com. Therefore, I decided to address this tid bit in my blog as it is not an in-your-face forum because I totally respect this company and the work they are doing in sustainability.

Consequentially, all reference to this company has been removed so as not to ruffle anyone’s tail feathers.

Here is the article:

Company X? has announced that it will construct a closed-loop recycling facility in Somewhere America to grind and wash post-consumer bottles and thermoforms for processing into its namebrand sheet products. The company says it is reducing the total carbon footprint of its product by bringing the material supply chain closer to production and offering its customers more choices of materials, including up to 100% post-consumer content PET.

?“We’re excited to bring bottle cleaning and sheet production together in a continuous process loop,” says company CEO. “Our factory design will streamline operations while delivering the recycled sheet products the market requires.”

Company X notes that it is among the first thermoforming companies in the food and consumer packaging industry to implement its own in-house recycling. With the new facility, the company will receive curbside-collected bottles to clean, grind, and extrude into sheet. Reducing the number of bottles going to landfills while providing high-quality material for customers has long been a goal for the company. Company X has been using recycled content in its packaging for more than 15 years, and over the last seven, it has diverted more than 1 billion discarded bottles from landfills.

While Company X has extruded sheet for internal use for 20 years, this marks the first time it will sell its namebrand sheet on the open market.

In addition to namebrand post-consumer rPET, the facility will produce LNO (letter of non-object) flake, allowing food contact with recycled material. Company X? has also commercialized an RF-sealable rPET grade of material to address customers’ bar sealing requirements for PET. Company X says that with only minor process adjustments, this material is a direct replacement for PVC sealing applications.

The recycling facility will be completed in two phases. In phase one, Company X will be adding an additional extruder for its namebrand rollstock. This will be completed in the third quarter of 2010. Phase two will be the addition of the bottle washing equipment, which is scheduled to be operational in the first quarter of 2011, with plans for additional extruders to follow.

Company X’s CEO said that integrating the bottle washing and grinding makes sense, given the amount of post-consumer material the company uses. With the completion of the in-house recycling facility, the firm will be able to streamline the recycling process to ensure that raw material meets Company X’s high standards.

Seeing as how I have been trying to figure out a way to integrate our RPET thermoforms into the existing PET bottle recycling infrastructure, I have A TON of questions for Company X.?

If any of you fine packaging and sustainability friends have any insight, please don’t hesitate to share!!! Sharing is caring!
    • What are the specs of the bales of thermoforms Company X is buying from the MRF?
    • Are they only PET thermoforms or are they mixed material thermoform bales?
    • If only PET thermoforms, is there enough QUANTITY of these types of packages available for the recovery of PET thermoforms to be economically sustainable?
    • How do they collect ONLY PET thermoforms without collecting “look a likes” like PVC, which will completely compromise the integrity of the PET bale, or PETG, which has a lower melting temperature and therefore adds inconsistencies to the recovery process?
    • Are you planning on integrating the PET thermoform scrap with the PET bottle scrap and extruding together? If so, how will you handle the different IVs between sheet grade PET and bottle grade PET?
    • If buying mixed material thermoform bales from the MRF i.e. PET, PETG, PP, etc., how are the different resins sorted for recovery? Are they blended together to create a low-grade, mixed resin flake for down-cycling applications? If so, who is buying this low-grade, mixed resin flake?
    • What kind of sorting technology is utilized to be able to generate a clean, quality stream of PET thermoforms for Company X to grind, clean, and extrude for direct food-contact packaging?
    • How are you competing with Asia for PCR PET?
While I am tickled pink that Company X is recovering thermoforms post-consumer in a closed-loop system, I don’t know how they are doing it! Perhaps the point, no?

That’s all for now; wish me luck tomorrow on my presentation!

Bio-based resin report!

Posted by Chandler Slavin on Oct 16, 2012 10:58:00 AM

Hello world! Today is officially the most beautiful day—the sun is shining and the weather is sweet. If I only I weren’t stuck in a cubicle…

Soooooo because I have had so many of Dordan's customers ask us about bio-based resins, I decided to compile a brief report, which details the various environmental ramifications one must consider when discussing bio-based plastics. Soon this report will be accessible on our website but because you are all so special, I have attached it below here. A sneak peak, per se. Wow I am a nerd.

Enjoy!

Bio-Based Resins: Environmental Considerations

Biodegradability is an end of life option that allows one to harness the power of microorganisms present in a selected disposal environment to completely remove plastic products designed for biodegradability from the environmental compartment via the microbial food chain in a timely, safe, and efficacious manner.[1]

Designing plastics that can be completely consumed by microorganisms present in the disposal environment in a short time frame can be a safe and environmentally responsible approach for the end-of-life management of single use, disposable packaging.[2] That being said, when considering any bio-based resin, there are some environmental considerations one must take into account. These include: end-of-life management; complete biodegradation,; its agriculturally-based feedstock; and, the energy required and the greenhouse gasses emitted during production.??

Before I expand on these concepts below, let us quickly discuss the biological processes that degradable plastics endure during biodegradation.

Microorganisms utilize carbon product to extract chemical energy for their life processes. They do so by:
    1. Breaking the material (carbohydrates, carbon product) into small molecules by secreting enzymes or the environment does it.
    2. Transporting the small molecules inside the microorganisms cell.
    3. Oxidizing the small molecules (again inside the cell) to CO2 and water, and releasing energy that is utilized by the microorganism for its life processes in a complex biochemical process involving participation of three metabolically interrelated processes. [3]
If bio-based plastic packaging harnesses microbes to completely utilize the carbon substrate and remove it from the environmental compartment, entering into the microbial food chain, then biodegradability is a good end of life option for single use disposable packaging.

End-of-life management considerations:

Because biodegradation is an end of life option that harnesses microorganisms present in the selected disposal environment, one must clearly identify the ‘disposal environment’ when discussing the biodegradability of a bio-based resin: examples include biodegradability under composting conditions, under soil conditions, under anaerobic conditions (anaerobic digestors, landfills), or marine conditions. Most bio-based resins used in packaging applications are designed to biodegrade in an industrial composting facility and one should require some type of certification or standard from material suppliers, ensuring compostability.

Unfortunately, little research has been done on how many industrial composting facilities exist in the United States and how bio-based plastic packaging impacts the integrity of the compost. However, the Sustainable Packaging Coalition did perform a survey of 40 composting facilities in the U.S., which provides some insight. According to their research, 36 of the 40 facilities surveyed accept compostable packaging. These facilities reported no negative impact of including bio-based plastic packaging in the compost. Of the 4 facilities that do not accept compostable packaging, 3 are taking certain packaging on a pilot basis and are considering accepting compostable packaging in the future. Of the facilities surveyed, 67.5% require some kind of certification of compostability i.e. ASTM, BPI, etc.

In addition, because value for composters is found in organic waste, I assume most facilities would not accept bio-based plastic packaging for non-food applications because the lack of associated food waste and therefore value. In other words, as Susan Thoman of Cedar Grove Composting articulated in her presentation at the spring SPC meeting, composters only want compostable food packaging because the associated food waste adds value to the compost whereas the compostable packaging has no value, positive or negative, to the integrity of the compost product.?

It is also important to note that because there are so few industrial composting facilities available, the likelihood that your bio-based plastic packaging will find its way to its intended end of life management environment is rare. While the idea of biodegradation and compostability for plastic packaging may resonate with consumers, the industrial composting infrastructure is in its infancy and requires a considerable amount of investment in order to develop to the point where it would be an effective and economical option to manage plastic packaging waste post consumer.

Complete biodegradability considerations:

A number of polymers in the market are designed to degradable i.e. they fragment into smaller pieces and may degrade to residues invisible to the naked eye. While it is assumed that the breakdown products will eventually biodegrade there is no data to document complete biodegradability within a reasonably short time period (e.g. a single growing season/one year). Hence hydrophobic, high surface area plastic residues may migrate into water and other compartments of the ecosystem.[4]

In a recent Science article Thompson et al. (2004) reported that plastic debris around the globe can erode (degrade) away and end up as microscopic granular or fiber-like fragments, and these fragments have been steadily accumulating in the oceans. Their experiments show that marine animals consume microscopic bits of plastic, as seen in the digestive tract of an amphipod.

The Algalita Marine Research Foundation[5] report that degraded plastic residues can attract and hold hydrophobic elements like PCB and DDT up to one million times background levels. The PCB’s and DDT’s are at background levels in soil and diluted our so as to not pose significant risk. However, degradable plastic residues with these high surface areas concentrate these chemicals, resulting in a toxic legacy in a form that may pose risks to the environment.

Therefore, designing degradable plastics without ensuring that the degraded fragments are completely assimilated by the microbial populations in the disposal infrastructure in a short time period has the potential to harm the environment more that if it was not made to degrade.

Agriculturally-based feedstock considerations:

Most commercially available bio-based resins are produced from sugar or starch derived from food crops such as corn and sugarcane.[6]Over the past few years, the use of food crops to produce biofuels has become highly controversial; the same may happen with bio-based resins. However, this is only if the scale of bio-based polymer production grows. According to Telles VP Findlen, “If the bioplastics industry grows to be 10% of the traditional plastics industry, then around 100 billion pounds of starch will be necessary, and there is no question that that will have an effect on agricultural commodities.”[7]

This sentiment is echoed by Jason Clay of the World Wild Life Fund. Because sugar is the most productive food crop[8] Clay explained, it makes an ideal feedstock for bio-based resin production; however, if all Bio-PE and Bio-PET came from sugarcane, we would need 2.5 times as much land in sugarcane. Unfortunately, this can not be done sustainably because, according to the Living Planet Report,[9] our current demand for the Earth’s resources is 1.25 times what the planet can sustain.[10] Put another way, on September 25th of this year our resource use surpassed what is sustainable. What this would mean as a financial issue is that we are living off our principle.[11]

Therefore, when considering bio-based resins, one should take into consideration the feedstock from which it is derived and the various environmental requirements that go into procuring said feedstock. While the current production of bio-based resins is not to scale to compete with sugarcane production for food, it is important to understand the environmental and social ramifications of sourcing materials from agriculturally based products.

Energy requirements and fossil fuel consumption of production:

Obviously sourcing plastics from bio-based resources as opposed to fossil fuel is an intriguing option for those looking to reduce the burden of packaging on the environment. However, if the energy required to produce bio-based plastics exceeds the energy consumed in the production of traditional resins, then the sustainability profile of bio-based plastics can be compromised.

When bio-based plastics first became commercially available, the processing technologies were not developed to the point where producing plastics from bio-based sources consumed less energy than producing traditional, fossil-fuel based plastics. However, the bio plastics industry has dramatically evolved and is now able to produce certain bio-based resins with less energy when compared with traditional resins. Natureworks Ingeo PLA (2005), for instance, is processed in such a way that it actually consumes less energy and emits fewer greenhouse gas equivalents during production when compared with traditional, fossil-fuel based resins.[12]

The Institute for Energy and Environmental Research (IFEU), Heidelberg, Germany, conducted the head-to-head lifecycle comparison on more than 40 different combinations of clamshell packaging made from Ingeo PLA, PET and rPET. Both PLA and rPET clamshells outperformed PET packaging in terms of lower overall greenhouse gas emissions and lower overall energy consumed and PLA exceeded rPET in its environmental performance.

According to the study, clamshell packaging consisting of 100 percent rPET emitted 62.7 kilograms of C02 equivalents per 1,000 clamshells over its complete life cycle. PLA clamshells emitted even less, with 61.7 kilograms C02 equivalents per 1,000 clamshells. Energy consumed over the lifecycle for 100 percent rPET clamshells was 0.88 GJ. This compared to o.72 GJ for the Ingeo 2005 resin, which is an 18% reduction in energy consumed.

Taken together, one would assume that the 2005 Ingeo PLA is a more sustainable option than traditional plastics, as manifest through this study. However, it is important to take into account the other dimensions discussed above, such as end of life management, complete biodegradation, and sustainable sourcing. By understanding the advantages and disadvantages of bio-based resins from an environmental perspective, packaging professionals can make informed material selections and truly comprehend the ecological ramifications of their packaging selections and designs.

Day 33: Dec. 11th, 2009

Posted by Chandler Slavin on Oct 16, 2012 10:57:00 AM

The next day I arrived to the office to find the following email that confirmed the results of our RPET samples’ test, which I had verbally received from another WM contact the day before:

Hi Chandler,

After speaking with our plant manager in Grayslake, PET clam shells should be recoverable from the recycling stream via optical and manual sorts. I can't say that's the case at all WM recycling facilities, or non- WM competitive facilities, so take that for what it's worth :). The material would end up in our PET bales.

However, that does not mean that the PET blister packs are the "same" as bottle grade PET bottles… as I understand it, the PET bottles have an IV rating of 0.78-0.80, or a "high rigidity," that bottle makers require. I do not know what UV rating your blister packs have, so I would recommend you discuss the technical aspects of your products with your engineers and your suppliers to determine the IV rating and other compatibility issues.

The main issue at this point, based on my research and discussions internally here at WM, is that any non-bottle PET that gets into a bale is typically discarded for landfill upon receipt at a PET bottler, even if a collection and processing company like WM can sort the PET blister packs from the recycling stream. Again, perhaps you can confirm or research this further with your suppliers.

I hope this helps! Good luck with your project. 

Hmmmmmm…

I then sent our head engineer the following inquiry:

Hey,

Do you have any idea what the “IV” of our supplier’s RPET is?

Thanks!

Chan

After a delectable lunch of an Italian beef with sweet peppers, I returned to find the following:

Spec for supplier’s RPET is IV>= 0.65; I believe it’s typically between 0.70 and 0.75.

Hope this helps.

I then checked the email from WM… “PET bottles have an IV rating of 0.78-0.80, or a ‘high rigidity’…”

Well, that’s not too terribly different than our 0.75 IV…now I am confused.

Tune in tomorrow to learn more about recycling in America!

AND check out this website that my contact from the APR suggested to find buyers of post-consumer plastic scrap: http://www.plasticsmarkets.org/. I just found it so I will let you know what I can find out in regard to who buys bales of thermoforms post-conumser. YIPEEEEEEEEEEEE.
