Hello!
Phew, Chicago has survived NATO. For residents of Chicago, the assembly of world leaders at McCormick Place over the weekend was inconvenient but cool. The Loop essentially shut down for four days, as all were warned of the closures and delays. Some lucky ducks even had a 4-day weekend because offices closed in anticipation of the protestors. Metra passengers were not allowed to bring food or drink on the train, and all bags were screened prior to boarding. As a resident of downtown Chicago, I was totally impressed by the extensive yet organized presence of cops; they circled every compromised building and lined the protest route. While one violent squirmish did break out between police and demonstrators at Michigan and Cermak, it was provoked by only a handful of anarchist protesters (The Blak Bloc”) and was contained with minimum force soon thereafter. Check out this pic I took Friday afternoon; notice the homeland security SUVs parked as far as the eye can see?
Today we are going to talk about developments with my LCA inquiry introduced in May 11th’s post. AND, to follow, for your viewing pleasure, pictures of home compostable bioresins a year after being home composted. Oh the anticipation!
To recap, what I mean when I say “my LCA inquiry,” is I am investigating the value of conducting an LCA of Dordan’s conversion process in order to: (1) establish a baseline off which environmental progress can be gauged, (2) compare with industry average and/or other conversion processes, (3) submit to available LCIA databases in order to provide more current data on the environmental profile of thermoforming, and (4) understand the methodology and application of LCA.
This investigation was inspired by the SPC suggestion of collective reporting among its member companies in order to demonstrate to outside stakeholders the value of SPC membership; and, research into LCA as per Dr. Karli Verghese’s presentation at Sustainability in Packaging (

After reaching out to the SPC re: aiding in the development of tools to perform an environmental assessment of Dordan’s conversion process, it was suggested I propose the idea to the membership; if there was membership interest, I could start a member-led working group dedicated to creating methodologies for LCA application to manufacturing processes.
Since I last posted, I had the opportunity to speak with LCA practitioners in the SPC membership about my Dordan LCA inquiry. Here are a couple conversation takeaways:
It is in a company’s interest to perform an LCA of its processes if said processes are more efficient/innovative than the industry standard; the industry standard for thermoforming can be teased from the available LCIA databases, like EcoInvent and the U.S. Life Cycle Inventory Database.
A good way to determine if your processes are more efficient than the industry average, and therefore an LCA is warranted, is to perform an inventory analysis: First, determine what your process’s main resource consumptions are i.e. water and electricity. Then, collect all information pertaining to the consumption of these resources via energy and/or water bills. Consult the industry average’s rates for these environmental indicators and see how your processes compare in the context of electricity and water consumption per some functional unit i.e. 10,000 packages produced.
If you determine that a full LCA is warranted, there are MANY ways to go about it. However, it is crucial that the results/findings of which are 3rd party-reviewed in order to validate the study. This was explained to me as being quite the process, and comes with a price tag.
Based on these insights, I am going to conduct an inventory analysis of Dordan’s energy consumption per a-yet-to-be established functional unit in order to compare with the industry average for thermoforming. Stay tuned!
My next post will discuss feedback from the last portion of the Walmart Packaging SVN meeting.
As an aside, in previous posts I alluded to an S+S Sorting pilot that looks to compare the reprocessing of thermoform vs. bottle PET flake. Remember? Anyway, my colleague at S+S has yet to get back to me with the results of this pilot. Stay tuned!
AND, do you remember way back when, at the start of Dordan’s Bio Resin Show N Tell research (
click here to download Report), when we tossed some of the home compostable certified bioresins (PHA, Cellulous Acetate) into Dordan’s home compost to see if the materials biodegraded? Well, this spring I analyzed the compost pile to determine the rate of biodegradation and am sad to report that little had changed in regards to the composition of the material: while lightened in color and somewhat more brittle, both the PHA and Cellulous Acetate, certified for home-composting, remain completely intact; you can even see the Dordan logo embossed on the cavity. Please note, however, that Dordan's compost pile has had its fair share of growing pains and the "bioplastics composting trial" may not reflect a 100% active home compost.
