Happy Friday!

So I have been working on a presentation on everything sustainability for one of Dordan's customers. Sustainability and Packaging 101, per se.

Anywoo, it took me two days and 190 slides to finish, but I am FINALLY DONE!

It's jam packed with good stuff--basically a summary of all my work to date--so check it out!

Sustainability and Packaging Presentation, Blog

Enjoy the heat-wave this weekend, my fellow Chicagoians!

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 25^th 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.

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.

This is awsome and all I want to say for today:

http://www.youtube.com/watch?v=WRPYccEXt-8

This company is super cool--they buy baled PET bottles and clean, grind, flake and extrude the material into RPET clamshells.

I am making a giant graph of all my research on recycling so get excited!

Tootles!

Ok, so I think I have dragged out the inevitable long enough. And resume recycling narrative:

Ring…Ring…

“Good Morning Dordan this is Sarah how can I help you? One moment please…”

Beep. “Chandler, Waste Management on Line 1…”

“Thanks.”

Suddenly I realized that this was the call I had been waiting on for almost 7 weeks: the results of our RPET clamshell samples’ test via the MRFs optical sorter. If our supplier-certified 70% post-consumer regrind PET clamshell packages are “read” like PET bottles via the recovery facility’s optical sorter, then perhaps we could integrate our clamshells into the existing PET bottle recycling infrastructure. If anything, the results would tell us if one of the many obstacles facing the inclusion of PET/RPET clamshells into the PET bottle recovery stream is NOT the inability to sort these two packaging types together.

I reach for the phone.

“Hello?”

“Hey Chandler!”

“Hey, nice to hear from you; how’s it going?”

“Great, thanks. I have the results from the MRF regarding your samples.”

“Ok, what are they; did they pass with the bottles?”

“Yes, there was no difference between the PET bottles and RPET samples as read by our optical sorter. So if RPET clams and PET bottles were moving down the line together, there would be no luminescent difference between the bottles and clams as they moved through our plastic sorting station. Again, the main point of the optical sorter is to see the difference between PVC and PET bottles, which look dramatically different when viewed via the optical sorter.”

“This is wonderful news!”

“Well, keep in mind that regardless of this, buyers of baled PET bottles DO NOT want clams in the mix.”

“And this is because fear of contamination, different IVs and perhaps melting points, no specs for mixed bales and on and on…?”

“Pretty much hit the nail on the head.”

“Well, I really appreciate you and WM going out of your way to help us figure this stuff out. We just want to recycle our packages—didn’t know how complicated it is!”

“Well we wish you the best of luck with your recycling initiative. Please let us know if there is anything else we can do for you…”

“Truly, thanks again.”

“No problem; take care.”

“You too!”

I hung up the phone.

Hmmmmmmmmmmmmm…what does this mean, I asked myself?

I think it means that the molecular structures of clamshell RPET and bottle PET are the same, at least was read via the optical sorter.

So how will this help us recycle our RPET thermoforms?

It illustrates that the reason RPET clams are not recycled with bottles has nothing to do with an inability to sort the two packaging types together. So if our RPET clams and PET bottles are read the same, they could be collected and baled, with no need for different sorting technology.

Good to establish, Chandler.

Suddenly I snapped out of my internal discussion; my two colleagues were waiting tentatively outside my cubicle, eager for the results.

“They passed!” I said.

“Sweet!” they replied in unison.

“So what does this mean for us?”

“Haha, I’m not quite sure yet…”

Tune in Monday for a summary of the different obstacles hindering the inclusion of RPET clams in the PET bottle recovery stream. Once established we will move on to discuss how the following determine the recyclability of a material/packaging type: supply, demand, and technology.

Have a splendid weekend! Its Friday, woop woop!

Happy Monday Funday! This post is to inform all of my packaging and sustainability friends that tomorrow is GO TIME! I have totally gotten my ducks in a row and can resume my clamshell recycling initiative narrative first thing in the morning. Get excited because I will finally release the results of our RPET samples’ test via the optical sorter (are they “read” like bottle-grade PET) AND bring you up to speed about why the results of this test are, unfortunately, another bread crumb, and not the end-all-be-all that I had hoped for at the onset of our recycling initiative.

WOHOOOOOOOOOOOOOO!

Hello world!

UG don't hate me for my failure to post AGAIN; it has been a heck of a day!

But guess what: I have been invited to assist a major retailer in their attempts to achieve zero waste for PET packaging, both thermoforms and bottles! But not only assist; be a CO-LEADER! I will be a research junky, therefore, as I hope to compile abstracts for the other co-leader and committee members to summarize my research over the past 6 months. And what that means to YOU my fellow blog readers is that I will be extra awesome with blogging because it has become a priority, again.

As I am sure some of my more diligent followers are aware, my blogging ebbs and flows with my existing work load AND the perceived value of continuing to investigate the logistics and economics governing the recycling of clamshells. Because of this recently ignited interest in my work on recycling PET thermoforms, I have been given the green light to (again) delve into researching waste management and recycling in America. YIPEEEEEE! I don’t think I would make a very good Sales woman anyway…J Work from home, here I come!

So tomorrow I will, and I promise, present the results of our RPET samples’ test and discuss how to move this initiative forward. If Canada can do it, so can we!

See you soon my packaging and sustainability friends!

Hello! Sorry I did not post yesterday! I took my first “vacation day!” It was awesome…slept late, had a wonderful brunch, went to the beach, and watched the Hawks game. I feel rejuvenated and ready to blog about recycling in America.

BUT FIRST, we still have to finish our recap of the Sustainable Packaging Coalition’s spring meeting in Boston. Where were we…

I left off discussing the keynote speaker’s discussion of our current approaches to production and consumption as being unsustainable. For a recap of the recap, check out my April 29^th post.

Let’s move on to the Bio-Material Procurement presentation, which I alluded to in the previous post. In a nut shell, this presenter argued that if we chose to utilize biomaterials to produce polymers that can replace tradition materials, we need to ensure that we consider the economic, social and environmental factors inherent in the scale and intensity required for the production of said bio-based resins. Wow that was a mouthful; let me try again.

Basically, if we are going to rely on agriculture to produce biomaterials for the creation of bio-based polymers, we need to understand what that requires from an economic, social and environmental perspective. Through a discussion of the Better Sugar Cane Initiative, the presenter illustrates how the development of procurement principles, criteria, protocols and standards facilitates the “sustainable” production of biomaterials used for the creation of bio-based plastics. I honestly don’t have much to say about this issue.

Next I sat in on the “Making a Case for Integrated Waste Management” presentation, which basically discussed the impending “product stewardship” or “extended producer responsibility” legislation. For those of you completely unfamiliar with this topic, check out my research at: http://www.dordan.com/sustainability_epr_report.shtml.

Basically, this presenter illustrated how waste management developed in the US and how our current waste management system is economically unsustainable due to the responsibility relying entirely on municipalities. This presenter, like many others, argued that the burden for funding waste management should be shifted from the municipalities to the producer/brand owner/first importer. In a nut shell: If you make it, you have to figure a way to recovery it post-consumer.

After this I went and listened to a presentation about other waste-to-energy technologies: one approach consisted of transferring trash into energy by essentially vaporizing waste into a multi-use syngas via a process known as plasma gasification; the other discussed innovating in composting, high solids anaerobic digestion and biomass gasification to produce renewable energy and high-quality value-added compost products.

Both technologies seemed super cool and the PERFECT solution to plastic packaging waste, which seemed a little fishy. I asked both presenters why these technologies were not utilized and the answer was because the price of natural gas is too cheap. Ha! Economics win again; I hate the real world.

There were a lot of other presentations, none of which I found particularly informative or interesting.

The next day I sat in on the “Making Packaging Composting a Reality,” which was AWSOME. Because Dordan is now working with bio-based resins that are certified to break down in an industrial composting facility, I really wanted to understand the likelihood that these bio-based resins would break down and could break down considering the existing infrastructure. The SPC had done a survey of numerous composting facilities in the US to determine their thoughts on compostable packaging. Luckily, bio-based clamshells DO break down in a compost pile; yippee! The only problem is, this end-of-life management option is WAY MORE attractive for food packaging because composters will accept the food waste along with the bio-based package because value for them lies within the organic i.e. food waste. Consequentially, it may be difficult “selling” our biodegradable packages to a composter post-consumer because they do not have food waste…

Regardless, it was really great to learn about industrial composting facilities and understand how the introduction of new bio-based polymers affects the overall integrity of the compost.

As an aside, the only thing that was found to NOT break down were “certified compostable” cutlery…go figure!

That’s basically it; sorry the info was a little basic. I hope that the fall meeting will be much more technical and really get into the gritty details behind why certain packages/materials are recycled and others are not i.e. its all about the money, honey.

Tune in tomorrow to witness the resurrection of my fallen recycling initiative.

Tootles!

Happy Monday Funday! I hope the weather is as beautiful for you as it is for me—sunny and 70, what more can a girl ask for?

SO where were we…that’s right, recapping the SPC spring meeting.

Oh, before I forget, there was one more thing I wanted to tell you about the Walmart Expo.

Prior to the Expo, in preparation for the Walmart SVN meeting (Sustainable Value Network), we were asked to do a little homework: this entailed going to a local Walmart and finding a package that needed a “sustainability makeover.” We were supposed to fill out a “packaging opportunities template,” which basically inquired into how one would redesign the package to increase its environmental profile while saving costs. This is what our team came up with:

PackagingOpportunitiesTemplate, FINAL

We decided to pick on a thermoformed package because we are thermoformers, although this one looks as though it was manufactured overseas, due to the perimeter sealing. Therefore, it’s not like we would be able to steal the business…I wonder what the sustainability profile is of an overseas manufacturer versus a domestic supplier…Ha!

Anywhoozy, it turns out that during the SVN meeting several of these “packaging opportunities” were to be presented to the entire conference—and guess what—I was one of the lucky four selected to present.

Basically I suggested that the package be right-sized and thermoformed out of RPET instead of PVC. The panel then inquired into how I would convey the same marketing presence with a reduced package AND prevent against pilferage. I was stumped. Perhaps include a recyclable paperboard backing, I offered? That totally stunk, however, because it suggested that paperboard is more “sustainable” than plastic, which I would not argue having performed extensive research on the topic. AND, according to the recent E.P.A. reports, the paperboard used in clamshell alternatives (labeled “other paperboard packaging” in the MSW report) HAS NO RECOVERY DATA—literally it is listed as neg., which means negligent. I wish I had known this during my presentation as it would have served our industry well. Rats!

Visit http://www.epa.gov/epawaste/nonhaz/municipal/pubs/msw2008data.pdf to see the break down of what is recycled and what is not in the paper world.

I guess my obsession with the recycle-ability of paperboard versus thermoforms can be summed up as follows:

I am at the Walmart Expo, working the booth. A prospect comes by, with whom I have had casual conversation in the past. Having seen his product at a competitor’s booth, I hassle him saying, “I saw your thermoformed trays at our competitor’s booth…and here you have been blowing me off all year…not very nice!” And he responds with, “we are getting out of thermoformed trays because they are not recycled.”

UG! What do you say to that? Prior to knowing that paperboard, which would be the alternative used for his packaging application, has no data for recovery post-consumer according to the E.P.A., I assumed that it was the more sustainable material because of its end-of-life recovery. But now that I know that in most cases, both thermoformed trays AND paperboard trays end up in landfills, I should have articulated a better argument for why thermoformed trays are still a wonderful packaging option.

It’s like when you have some kind of social confrontation and find yourself tongue-tied only to later come up with the best “come-back” ever! That’s what this was like; I needed a good come back, both for the “packaging opportunities” presentation and the fellow who thinks paperboard is better due to its end of life recovery. Next time…

A couple other points about the Walmart Expo:

As discussed in a previous post, the Walmart Scorecard has a “transport module,” which takes into account the inputs/outputs of shipping a package from the point of conversion/manufacture to the point of fulfillment. Supposedly the filled packages’ journey to the point of purchase is covered in another metric…

Anyway, I asked if the scorecard takes into account/intends to take into account the environmental ramifications of overseas manufacturers versus domestic manufactures. After all, long before my appointment at Dordan, we lost business to China because of the super duper low prices of labor and therefore commodities. And considering all this sustainability jazz, one would think that sourcing domestically would have some kind of impact on ones Score (think shipping, environmental regulations, labor regulations, etc. in China versus the States)…unfortunately, that is not the case. According to a member of the SVN, Walmart considered having a “point of origin” metric but determined that it was unquantifiable and would not resonate with their suppliers. Go figure!

A SVN member then articulated the following inquiry, which tickled me pink: Is the Scorecard going to take into account the inks, laminates, and sealants used on paperboard packaging? The member who voiced this inquiry qualified this question with some data, specifically, that even the tiny amounts of hazardous material in these various substances can have a high toxicity on the social and environmental environments.

This inquiry was answered as follows: Again, they considered adding this metric into the Scorecard but did not because they didn’t believe that these factors had a large enough effect on the overall “environmental profile” of a package. Supposedly, if we prove otherwise, they will consider adding this metric into the scorecard…

Lastly, Walmart is rolling out their Scorecard to other countries. I asked if each Scorecard used different recovery rates depending on the country it was being utilized for. In other words, Canada has a better recovery rate for most packaging materials that the U.S.; therefore, is their Scorecard going to use Canadian recovery data or American? According to the SVN, each Scorecard will be country specific, using recovery data from the country considered.

Wow, another marathon of an email. I’m sorry to keep rambling, I just have so many thoughts! I will continue tomorrow with the SPC recap and quickly move into resuming my clamshell recycling initiative.

Go packaging!

Greetings my packaging and sustainability friends!

Guess what: I have a meeting with our City Official on Monday to determine what the economics are governing waste management in our region (Woodstock, IL). After all, municipalities are the bodies that dictate to haulers like Waste Management what materials should be recovered post-consumer. If we want to figure out why non-bottle rigids (clamshells) are not recycled in our region, perhaps we should talk with those who determine what materials should be collected in the first place!

Before I get ahead of myself (I still have to summarize all my recent findings about non-bottle rigid recycling and PET recycling via the American Chemistry Council’s research), shall I recap my experiences from the SPC meeting in Boston last week?

Well, Boston itself is a BEAUTIFUL city; it is the most “European-like” city I have been to in the States. Like Chicago, Boston has lots of classic architecture juxtaposed with modern, glass and steel structures, which makes for a very aesthetically interesting skyline.







While there, I went to my first professional hockey game: The Bruins in the first game of the playoffs! It was totally radical! Very barbaric and hedonistic, with all the fighting, cheering, eating and drinking; I now know why it is one of America’s favorite past-times!



The spring conference for the Sustainable Packaging Coalition was okay. Granted the volcanic eruption made it difficult for several international speakers to attend—thereby making SPC staff scramble to find new speakers last minute—the content of the presentations was still a little “fluffy,” in my opinion. Perhaps my disappointment with the content can also be attributed to the fact that the only other SPC conference I attended marks the beginning of my career at Dordan. Consequentially, all the information presented at that conference was super new and exciting and I acted as a sponge, sucking it all up. Because I have been doing nothing but researching since the fall SPC conference, maybe my understanding of “sustainability” has reached an elevation that requires increasingly technical presentations in order to satiate my appetite. That being said, I did learn several things from the presenters.

The first presentation I sat in on titled “Using the SPC’s Indicators and Metrics Framework” discussed how to use the SPC’s metrics for sustainable packaging in the procurement of LCA and LCI data. It appears as though these metrics can be used to determine life cycle inventory data for certain processes, thereby helping to establish a base line for companies such as ours to measure sustainability improvements upon. This is what I learned:

• “Gate-to-gate” means the environmental inputs (energy, water, etc.) and outputs (greenhouse gas equivalent emissions) required/emitted during the production of extruded roll stock through the conversion phase for the manufacture of thermoformed packages. In other words, data that pertains to Dordan’s operations of ownership i.e. the roll stock we buy to convert to thermoformed packages. You dig?

• “Cradle-to-gate” means the inputs and outputs required/emitted during the raw material extraction. This term can also extend further throughout the supply chain i.e. to the converter or CPG company. Basically, it is a designated point along the supply chain that aids those in the procurement of LCI data.

• “LCI” means life cycle inventory data and it takes into consideration the inputs and outputs required/emitted throughout the entire life cycle of a product/material/etc. This is organizational-specific data and is concerned primarily with the environmental profiles of PROCESSES i.e. extrusion, conversion, fulfillment, etc.

• Eco-invent is a free LCA database; however, many LCA databases are proprietary and costly to gain subscription tool.

• At least three different LCI data entries are required to validate the industry average data (LCA)…this is confusing to me, too.

Because of the “rules” governing the conference, I am unable to provide the name of the presenter/speaker or the company/organization that he/she represents.

That being said, the key note speaker for the conference was speaking on behalf of a very prominent NGO dedicated to the environment. This speaker gave a very insightful but somber presentation on how our world’s current approaches to production and consumption are NOT sustainable; not even close. According to this presentation, “the current demand for the Earth’s resources is 1.25 times what scientists believe our plant can sustain. And by the way, that’s with 6 billion people—not the 9 billion world population predicted by mid-century.” The main argument of this presentation was that we need to increase the production on our already-producing land (land for agriculture) while not further depleting our natural resource reserves (water, top soil, biotic resources, etc.). Basically, we need to be much smarter and innovate in order to continue utilizing our land for the production of food. This argument curtailed on another, which was further explicated in a latter seminar titled “Bio-material Procurement;” in a nut shell, we should not use our already strained agricultural land to grow materials like corn for the feedstock of the next generation of bio-based polymers because this land is already required for the production of FOOD for our ever-growing and consuming population.

WOW, I have already rattled a lot. How about I stop for today and continue to expand on the conference in tomorrow’s post.

Thanks for listening!

Oh, and just for fun, here are some pcitures of a Bostonian street performer and our Sales Manager, so eager to assist!
