Helllooooo my packaging and sustainability friends!

Today I am going to begin discussing the insights of the SPC meeting I attended in San Diego last week. As alluded to in yesterday’s post, these meetings are conducted under the “chatham house rule,” which means that “participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s), nor that of any other participant, may be revealed.”

I flew into San Diego on Monday to catch part of the pre-conference workshops—specifically—the “SPC Labeling for Recovery Update” as I spend a lot of time researching end of life management of packaging materials. One of the arguments I make in my Recycling Report is that the SPI ID code on the bottom of plastic packaging is an inefficient means of segregating plastic by resin type for its end of life reprocessing in manual sortation systems. Do note, however, that sortation by resin type post-consumer was never the SPI’s intention with these codes—it was more constructed as a form of intra-industry communication. ANYWAY, the SPC’s Labeling for Recovery Pilot looks to model itself a bit off the UK’s Labeling for Recovery scheme insofar as it is intended to communicate to CONSUMERS what packaging materials are recycled, what may be recycled, and what currently are not recycled. For those of you unfamiliar with the UK’s labeling scheme, it began as a project by WRAP, which was subsequently re-identified as OPRL Ltd. (On Pack Recovery Label). OPRL is now used on more than 90% of grocery packaging in the UK and has reportedly resulted in increased understanding by consumers of what is recyclable and what is not, thereby elevating recovery rates of packaging waste post consumer. The catch, for lack of better words, is that companies wishing to use this labeling scheme on their packaging must pay the “distributors” of this scheme an agreed upon annual fee. Like most “certifications,” I believe, –be it SFI, USDA Organic, Green Dot, etc.—money must be generated by those wishing to use said label/certification in order to ensure the proper distribution and implementation there of. I just read this article, which explains how SFI is in some hot water as many Fortune 500 companies that previously used said certification are removing it from new product packaging due to the unethical implications of this entire certification system. Therefore, it is very, very important when using/issuing a labeling scheme/certification that due diligence is taken throughout the supply chain to ensure that the label conveys to consumers what it is intended to convey, without falling into the deep, dark waters of GREENWASHING, dun dun dunn. Sorry I am getting way off track.

So, the SPC’s Labeling for Recovery Project attempts to present a legitimate, uniform labeling scheme that educates consumers on what types of packaging can and cannot be recycled currently in America. The workshop got in somewhat of a debate, however, over what percentage of recovery/REACH data per packaging material is considered “recyclable,” vs. “check locally,” vs. “not currently recycled.” Obviously, most participants in the workshop represented some type of packaging material, and no one wants to have a “not currently recycled” label on their packaging, regardless of if that is the reality of the situation. At first it was articulated that the FTC’s recently revised Green Guides would be used to determine what is considered “recyclable” (60% or more American communities have access to facilities that can recycle packaging X post-consumer) vs. “check locally” (20%-60% “…”) vs. “not currently recycled” (less than 20% “…”). This type of data collection, that is, what percentage of Americans/American communities have access to recycling facilities that can reprocess packaging material X, is called “REACH” data, though I myself am a little confused about the difference between having access to recycling facilities vs. actually recycling packaging…

ANYWAY, the workshop spent a considerable amount of time discussing:

Holes in existing data sets, be it REACH data or recycling/recovery data (American data sets don’t consider incineration with energy recovery as a form of “recovery,” which is part of the reason that the “recovery” rates of packaging waste in the EU far exceeds that of America);

How incineration with energy-recovery would be incorporated into the labeling scheme, though little post-consumer waste is incinerated in America due to its sour reputation from the early 1990s;

AND how private/closed loop recycling schemes, like those implemented by RecycleBank and TerraCycle, would be included into the construction of this labeling scheme as these non-national facts and figures are not currently incorporated into the US EPA/ACC data sets on packaging waste recycling/recovery.

As you can see, something so simple as trying to educate consumers about what is recycled and what is not recycled is not NEARLY as easy as it seems—you have to deal with lack of uniform/accurate data sets, conceptual discrepancies between using data set A (REACH data) vs. data set B (recycling data), plus how to incorporate compostability data, incineration with energy recovery data, private/closed loop recovery scheme data, and much much more! Fun stuff, eh!??!

After the slighty around the bush workshop, I had some time to kill before the “networking reception” that night, so I took a walk along the coast, and spotted a mini gondola, see!

Hello and happy Friday!

I leave on Sunday for Walmart’s Sustainable Value Network meeting and Expo. I will be sure to take tons O notes for you, my packaging and sustainability friends, though we still have like a million of Dr. Narayan’s slides to get through PLUS all the feedback from the SPC’s meeting in San Diego last week. JEEZ I have my work cut out for me. I will be blogging, however, all next week to catch up on all the interesting content.

Have a splendid weekend.

Hey guys!

I'm back! The Walmart SVN/Expo was great! I will give you the skinny ASAP. In the meantime, however, I wanted to revise/clarify some of the claims made in my April 7th post, titled "Feedback from SPC's Labeling for Recovery Project." The lovely Anne Bedarf, project manager of the SPC, who works extensively on this Project, sent me the following email:

Hi there Chandler—great to see you in Arkansas, hope you make it home fine.

Thanks for blogging on the Labeling for Recovery Project! There were, however, a number of errors/clarifications needed that I’d like to bring to your attention. I’ve put them in below in bold. Feel free to quote me on them. Let me know if you have any questions, and thanks.

Kind regards--AnneB

As per her request, check out the revised post below!

Helllooooo my packaging and sustainability friends!

ANYWAY, the SPC’s Labeling for Recovery Pilot looks to model itself a bit off the UK’s Labeling for Recovery scheme insofar as it is intended to communicate to CONSUMERS what packaging materials are recycled, what may be recycled, and what currently are not recycled. For those of you unfamiliar with the UK’s labeling scheme, it began as a project by WRAP, which was subsequently re-identified as OPRL Ltd. (On Pack Recovery Label). It actually became a subsidiary company created by WRAP and the British Retail Consortium. WRAP is still WRAP. OPRL is now used on more than 90% of grocery packaging in the UK and has reportedly resulted in increased understanding by consumers of what is recyclable and what is not, thereby elevating recovery rates of packaging waste post consumer. The catch, for lack of better words, is that companies wishing to use this labeling scheme on their packaging must pay the “distributors” of this scheme an agreed upon annual fee.

Sorry I am getting way off track. Totally agree—BUT—this label is NOT a certification. It’s more like the nutrition label for recyclability. Also there will be no fees charged during the pilot—we are looking at fees for long-term implementation mainly to ensure that it is properly used and that we have proper data collection.

So, the SPC’s Labeling for Recovery Project attempts to present a legitimate, uniform labeling scheme that educates consumers on what types of packaging can and cannot be recycled currently in America. The workshop got in somewhat of a debate, however, over what percentage of recovery/REACH data per packaging material is considered “recyclable,” vs. “check locally,” vs. “not currently recycled.” Obviously, most participants in the workshop represented some type of packaging material, and no one wants to have a “not currently recycled” label on their packaging, regardless of if that is the reality of the situation.

This type of data collection, that is, what percentage of Americans/American communities have access to recycling facilities that can reprocess packaging material X, is called “REACH” data, though I myself am a little confused about the difference between having access to recycling facilities vs. actually recycling packaging…This is a legitimate concern. Our first filter is Reach data—per FTC, related to collection. Our secondary filter is actual recyclability and a number of “prohibitives” will be on an “exceptions” list. For example, PET bottles are widely recycled; however, with a PVC shrink under our system they will not be labeled as such but as not yet recycled.

ANYWAY, the workshop spent a considerable amount of time discussing:

Holes in existing data sets, be it REACH data or recycling/recovery data (American data sets don’t consider incineration with energy recovery as a form of “recovery,” which is part of the reason that the “recovery” rates of packaging waste in the EU far exceeds that of America);

How incineration with energy-recovery would be incorporated into the labeling scheme, though little post-consumer waste is incinerated in America due to its sour reputation from the early 1990s; There is actually no way this could be included because we can’t determine final end use from reach data, MRF info, or prohibitives in recycling.

AND how private/closed loop recycling schemes, like those implemented by RecycleBank and TerraCycle, would be included into the construction of this labeling scheme as these non-national facts and figures are not currently incorporated into the US EPA/ACC data sets on packaging waste recycling/recovery. This isn’t totally true. You’d have to ask EPA, but remember EPA only looks at Rates, not Reach. Recycle bank helps get curbside recycling started, and those communities that have curbside are included in reach data analysis. I think that part of the discussion was more about drop-offs that weren’t part of a municipal program. TerraCycle isn’t included because we don’t really think mail-back is currently an effective recovery strategy—and after all—how would one measure “reach” for mail-in?

As you can see, something so simple as trying to educate consumers about what is recycled and what is not recycled is not NEARLY as easy as it seems—you have to deal with lack of uniform/accurate data sets, conceptual discrepancies between using data set A (REACH data) vs. data set B (recycling data), plus how to incorporate compostability data, incineration with energy recovery data, private/closed loop recovery scheme data, and much much more! Fun stuff, eh!??!

Thanks Anne!!!

Hello and happy Friday!

I just wanted to wish you all a happy weekend-- I leave for San Diego super early Monday morning for the Sustainable Packaging Coalition's spring meeting-- so I will resume blogging upon my return late next week. Check out the agenda, it looks great!

I will be sure to take tons o notes to share with you, my packaging and sustainability friends!

And Dordan's website redesign is coming along swimingly! I can't wait for you all to check it out!

AND, check out Dordan's ad in Shelf Impact that came out today!

Hey yall!

Sorry for my absence!

The Sustainable Packaging Coalition’s meeting in San Diego was GREAT! Seriously, I learned A TON. My favorite was the panel discussion of trash in the ocean (33% of all marine debris is cigarette butts!) and the science of biodegradation in landfills. Also really interesting was the presentation on the recently revised FTC Green Guides by the Senior Attorney of the FTC. Due to the legalities of these meetings, however, I am unable to refer to presenter by company/brand; therefore, note that I ALSO had a very interesting exchange with a sustainable cleaning products company in regard to their recently unveiled molded pulp/PP bag (bag N a box) packaging for household cleaning products.

I will cue you in on this exchange, along with updates on the applicability of LCA/LCI and much much more tomorrow afternoon!

Thanks for your patience!

Hello and happy almost Friday day!

Today we are going to talk about the process of deriving carbon from annually-renewable resources for synthesis into bio-based polymers. As per yesterday’s discussion, substituting bio-based carbon for petro-based carbon provides a value proposition in the context of material carbon footprint for plastic packaging.

Slide 7: Carbon Footprint Basics—Value Proposition

Consider the following chemical process for manufacturing traditional, fossil-based plastics:

Fossil feedstock (oil, coal, natural gas)-->Naptha-->ethylene/propylene-->polyethylene (PE), polypropylene (PP)

Now, consider the process of manufacturing bio-based plastics from a renewable feedstock:

Bio/renewable feedstock (crops and residues i.e. corn, sugarcane, tree plantations i.e. lignocellulosics, algal biomass i.e. algae)-->BIO monomers, sugars, oils (continue)

These BIO monomers, sugars and oils can then be synthesized into EtoH, which is then used to make ethylene/propylene, the building blocks of PE and PP;

OR, these BIO monomers, sugars and oils can be synthesized to make PLA and PHA.

The difference between something like PLA and the PlantBottle, therefore, is that the PlantBottle derives its carbon from biomass, as explained in the process above, yet has the same chemical composition as tradition, petro-based PET. Therefore, it is not designed to “biodegrade” in an industrial composting facility or others, whereas PLA, which is of a different chemical composition though it derives its carbon from, like the PlantBottle, an annually renewable source, is designed to “biodegrade” in the intended disposal environment as stipulated by the manufacturers of PLA. Check out the molecular structures of PLA vs. PP on the 7th slide of Narayan’s presentation; as you will see, the carbon, highlighted in red, can come from petro-based or bio-based feedstocks. Cool, huh!?!

Slide 8: Understanding the value proposition for bio carbon vs. petro/fossil carbon

Narayan then went on explaining the difference between old carbon (fossil fuel) and new carbon (crop residue/biomass). Consult the 8th slide of the PPT for an explanation of how old carbon is synthesized from new carbon.

Consider the following processes of synthesizing new vs. old carbon:

CO2 (present in atmosphere) + H20-->photosynthesis (1-10 years)--> (CH20)x +O2-->NEW CARBON (biomass, forestry, crops)

Vs.

C02+H20-->photosynthesis (1-10 years) -->(CH20)x-->-->-->(10,000,000 years)-->OLD CARBON (fossil resources i.e. oil, coal, natural gas)

He then argued that all the criticism about manufacturing plastics out of non-renewable sources is misplaced because it doesn’t really matter where you get the carbon from—be it old or new carbon. The issue, however, is the rate and scale at which we have been taking old carbon (oil) out of the earth: it is inherently unsustainable to continue to derive carbon from fossil fuel for synthesis into disposable plastic packaging because it takes millions of years to create old carbon from the process described above, whereas it takes just 1-10 years to derive new carbon from crop residue/biomass.

Does that make sense?

He concludes: “Rate and time scales of CO2 utilization is in balance using bio/renewable feedstocks (1-10 years) as opposed to using fossil feedstocks.”

Goodness!

Hey guys,

As per March 15th’s post, I was interested in what the newly released bale specs for non bottle rigids means for the progress in recycling PET thermoforms. As such, I sent my contact at APR the following email:

Hey!

This is Chandler with Dordan—we spoke a while ago about the obstacles facing the inclusion of thermoform packaging in the recovery infrastructure. Remember?

I hope this email finds you well!

I wanted to applaud the efforts of APR as described in Mike Verespej’s PlasticsNews article, “Recycling group creating new bale specifications.” After speaking at several industry events about the need for specs for non-bottle rigids, I was delighted to discover this bit of news. So congrats!

Does APR have plans to develop specs for thermoform only (PET OR all mixed resins) bales, too?

I look forward to your feedback!

The next day, I received this response from the Technical Director at APR, David Cornell:

Chandler,

Thank you for your interest in plastics recycling.

APR has always been interested in more good raw material. To that end we have Design for Recyclability Guidelines, Guidance Documents, and Model Bale Specs. APR is a data-driven, science-based organization. We are also reflective of good business practices. To that end, we have provided our Model Bale Specs to help buyers and sellers establish common language for commercial transactions. We do that by reflecting what is happening and what we would see as logical extensions of proper commercial practice. Our Model Bale Specs include those materials to be included in specific bales and those materials not to be included and suggested levels of various extraneous materials along with best practices on bale size, density, and assembly.

The APR Rigids Committee is working on bringing some suggested standardization to the description of bales of various materials. More uniformity means both buyers and sellers benefit. This will be an ongoing activity as has been the description of both PET and HDPE bottle model bales.

To your question, the growing interest in just PET thermoform collection and recycle will very possibly lead to the commercial need for common description afforded by Model Bale Specifications. As the tolerances to various inclusions are fully understood, Model Bale Specs can be usefully written and likely will. Model bale specs for bales of mixed thermoforms will depend on the commercial need for such and establishment of commercial practices such that a document aids commerce. Bales of items made of incompatible resins, such as PET and PVC, are of less value than bales of those separated. Certainly we know of mixed resin bales, but see much more value in model bale specifications for higher valued, generic resin bales.

And I continued…

Hey!

Thanks for the email and detailed explanation! From what I understand, there are several companies that have the capacity to reprocess post consumer PET thermoform containers into new products but can’t find any thermoform bales to purchase for said reprocessing. If demand for PET thermoform bales exists, what would it take to create PET thermoform bale specs? How do I go about moving the recycling of thermoforms forward as a representative of a thermoform manufacturer?

And his response:

Chandler,

The first step is to have a stream of useful material. That means today just PET with no look-alikes. The look-alike PS, PETG, and PLA need their own bales. It also means thermoforms that do not have unfriendly adhesives. The APR protocol on thermoform adhesives is on the website to guide in assessing adhesive and labeling choices.

When streams of such useful material are available, then it will make economic sense for MRF’s to isolate and sell such bales. Until we reach the MRF-provided bales, we will likely be looking for controlled flow PCR such as bakery trays from retail bakeries and food stores.

The issue is always one of critical mass for the collectors, sorters, and reclaimers. Jump starting as is going on in Canada really helps.

David

Round and round we go!

Tune in tomorrow for a description of part one (Bio-based products concepts) of Dr. Narayan’s workshop on the science of “biodegradable polymers.”

Hello everyone!

Another gloomy day in Chicago—I can’t wait to go to San Diego next week for the Sustainable Packaging Coalition’s spring meeting! AND, I just booked flights to Rogers, Arkansas, for the Walmart SVN meeting and Expo. Though Dordan is not exhibiting this year, I am excited to see what other vendors are offering and get updated on Walmart’s sustainability initiatives!

So I am about half way through TerraCycle CEO Tom Szacky’s book, “Revolution in a Bottle.” It is really, really good, and inspiring! I thoroughly suggest you get yourself a copy today! That which I like so much about his story is his awareness into the economic realities of the market place: one of his main arguments is that the majority of consumers will NOT pay more for a green product; while everyone wants to do well by the environment, few are willing to pay for it. His whole approach, therefore, is to be able to provide green products at a competitive price and performance as those currently on the market. And the best way to do that? Use what is considered waste as your feedstock. BRILLIANT.

I met with TerraCycle’s VP of Global Brigades today to learn more about the logistics of their approach to recycling/reusing hard-to-recycle materials and products. Basically, they have a brand pay to finance the brigades (collection of materials and shipment) and in return, TerraCycle upcycles or recycles the collected materials thereby extending the brand’s life post consumer. It’s a win-win: the brand gets consumers to participate in their identity by collecting it’s waste i.e. Capri-Sun bags, thereby strengthening the consumers relationship with the brand and the brand’s perceived environmental stewardship; the collected “waste” is then recycled/upcycled into new products, further extending the life of the brand and/or creating a value-added product for the market while diverting hard-to-recycle materials from landfill! From how I understand it, TerraCycle is privatizing waste management—cutting out the MRF, brokers, municipalities, etc, and creating a simplistic supply chain based on consumers’ willingness to participate and a team of innovative designers. As discussed numerous times in my Recycling Report, the whole problem with recycling thermoforms is the high cost of manual sortation and the lack of investment in automated sorting technologies. If consumers are doing the sorting themselves at places where people congregate i.e. schools, church, retailers, etc, then the whole issue of manual vs. automated sorting systems at a MRFs is totally bypassed. These materials don’t even make it to the MRF—TerraCycle sort of IS the MRF! Crazy, right?!?!

The wheels are churning upstairs for sure!

So let’s discuss the first part of Narayan’s PPT on the science of biodegradable polymers. Please visit March 16ths post to download the presentation and follow along with my descriptions per slide number.

Part one: Bio-based products concepts

Slide 6: What value proposition to bio-plastics offer?

As discussed in March 16ths post, there are two components to “sustainability” as it pertains to packaging: the carbon footprint of the package and the end of life management of the packaging material. Therefore, today’s discussion will focus specifically on the carbon footprint dimension of the multi-faceted conception of “sustainability.”

Narayan began the first part of the workshop by explaining that bio-based polymers, that is, plastic that derives its feedstock from an annually-renewable resource, like starch, provides a value proposition in the context of material carbon footprint. He states: “Switching from the “petro/fossil” carbon in plastics to “bio-renewable” carbon reduces the material carbon footprint.”

He then went into a discussion of LCA, as many in the industry have argued that petro-based polymers are “better” than bio-based due to the energy-intensive process of creating carbon from bio-based resources as opposed to petro-based resources. And here is what he had to say:

This has nothing to do with the PROCESS. Those who manufacture bio-based polymers must ensure that their process of generating polymers from renewable resources is better than or equal to the existing process of creating polymers from fossil fuel. However, this isn’t your or my problem. I am not advocating that the process of creating plastic from crop residue is not important when understanding the “sustainability” of these non-traditional resins; I am arguing that that discussion is a separate one then the discussion we are having right now, which is understanding how substituting petro-based carbon with bio-derived carbon is a value added proposition in the context of material carbon footprint.

In a nut shell: there is a value proposition in switching from petro-based carbon to bio-based carbon for plastic material feedstock. This value proposition has nothing to do with the manufacturing process of petro vs. bio-based polymers; it has to do with switching from a non-renewable source of carbon to an annually renewable one. If carbon in polymers can originate from non-renewable fossil fuel or annually-renewable crop residue, why not substitute the renewable carbon with the non-renewable!?!

But how do you derive carbon from crop residue for synthesis into bio-based polymers?

Tune in tomorrow for Chemistry 101.

Hello yall! It is a BEAUTIFUL day in Chicago—almost at 60 degrees! I am writing you from my favorite downtown Starbucks. As per my repeated blog statements, today I will begin discussing Dr. Narayan’s workshop on the science of biodegradable/compostable/bio-based polymers.

Context: Dr. Ramani Narayan is a Distinguished Professor in the Department of Chemical Engineering & Materials Science at MSU. He conducted a four-hour workshop at the Doubletree Resort in Orlando as part of Pira International’s Sustainability in Packaging pre-conference workshops.

Download the presentation here: NARAYAN, Sustainability in Packaging Workshop, Intertech-Pira

Please note that it is extremely technical presentation; therefore, for an explanation of each slide, visit the corresponding blog posts’ sections. Due to the depth and scope of the workshop, this information will be discussed over a series of several blog posts. Today’s focuses only on the introduction of packaging and sustainability in the context of global warming and end of life management.

“Understanding material feedstock choices and end-of-life strategies for Packaging Sustainability: Biobased and Biodegradable/Compostable Plastics”

Introduction:

Narayan is a very entertaining speaker! He began the workshop by jokingly aligning himself with the plastic folk (“are there any paper people in here?!?”), emphasizing that regardless of what camp you fall into, the underlying themes of the workshop are applicable to any packaging material type. Because the allotted time for this workshop was four hours, Narayan began by contextualizing the relationship between the environment and packaging, subsequently explaining the organization of the material to move from a macro to micro level.

The three “legs” of sustainability, which I am sure you are all very familiar with, was the first slide; that which was unique about Narayan’s treatment, however, was his emphasis on “carbon cycling” within the “environmental” leg of the sustainability concept. He then used this emphasis on carbon cycling between land/air/water/energy (renewable vs. fossil) to begin an explanation of global warming, claiming that regardless of if you believe in the concept or not, the reality of the situation is that the amount of carbon in the atmosphere has been substantially increasing since the industrial revolution. While there are natural origins of carbon emissions into the atmosphere i.e. volcanic explosions, the rate at which carbon has increased in our atmosphere is without a doubt the result of human activities inherent in the process of production and distribution.

The second slide illustrated this reality, showing how the “annual emissions to the atmosphere (Pg C),” though rising since the 1850s, dramatically spikes from 1950 to present day.

Narayan explained the whole “global warming” thing as follows: C02 is a heat trapping gas—there is and will always continue to be a healthy amount necessary to sustain the chemistry of the atmosphere. However, the amount of C02 emitted into the atmosphere has dramatically increased since the 1950s. It’s a simple cause and effect relationship: more C02 is being emitted into our atmosphere; C02 is a heat trapping gas. Consequentially, the temperature of the planet will rise, plain and simple. Narayan then argued that our role as stewards is to MANAGE the C02 distribution in our atmosphere, not eliminate it. If we continue to do nothing, the temperature will continue to climb, and eventually, we will reach a “tipping point,” although it is impossible to know when that will be and the inherent repercussions thereof.

Soooo what does this have to do with packaging? Everything—from the Walmart Scorecard to the metrics constructed by the Global Packaging Project, the world of “sustainable packaging” is intent on being able to quantify the “carbon footprint” of it's product(s)/package(s).

Narayan then explained how there is confusion insofar as carbon footprint is but one of two important concepts when trying to quantify the sustainability of a product/package. Therefore, it is important to understand “sustainable packaging” as living in two different, but related, camps: the first is that of the carbon world; the second, the end of life management world. Neither one is more important than the other—it just depends on what your priorities are.

Taken together, Narayan argued that the two main opportunities facing packaging are: carbon footprint reductions—global warming/climate change issue; and, end-of-life management—recycling, waste-to-energy, biodegradability in targeted disposal systems like composting (compostable plastics). It is important to understand these two opportunities as different but related when making decisions about packaging.

Before moving into a discussion of bio based products concepts, Narayan touches on the notion of “biodegradation.” He explains how “biodegradable” is sort of like the new “it” world as conveyed via consumer preference (“biodegradability” is often cited as the number one desired sustainable packaging attribute in consumer market research studies, though “recyclable” is also a repeated favorite), yet technically, EVERYTHING is biodegradable—we are too! Given time and the environment, everything will break down and be consumed via microorganisms present in the natural environment. However, without specifying a disposal environment in which said product/package will “biodegrade” i.e. industrial composting facilities, anaerobic digestion, etc.—the term means absolutely NOTHING!

He then proposed the following inquiries:

How does your package fit into “sustainability”?
What is the feedstock?
What is the end of life?

We will now move onto a discussion of how to gain a value proposition in the context of packaging material feedstock.

Part 1: Bio-based products concepts

To come.

Thanks for your time my sustainable packaging friends! For those of you attending Greenerpackage’s Sustainable Packaging Symposium in Chicago, have a blast in my city!!!

Hello my packaging and sustainability friends! I can't believe it's already the end of the day and I haven't given you ANYTHING from the conference. I am very sorry! Busy as a bee!

I did, however, receive a bunch of really great information from Dr. Ramani Narayan, professor in the Department of Chemical Engineering and Materials Science at Michigan State, in regard to bio/oxo/compostable resins. Pending his approval, I will upload his presentation for your viewing pleasure! Talk about a great workshop!

AND, not to rub it in or anything, but I leave tomorrow for a full week of vacation!!!! Therefore, I will not resume blogging until the following Monday.

BUT, we just finished designing our soon to be live ad on Packaging World’s homepage! Get a sneak peak here!

I will miss you! Have a great week without me in the world of sustainable packaging!
