Hey!

Dr. Karli Verghese definitely knows a thing or two about a thing or two when it comes to life cycle analysis.

She is the author of a book chapter titled “Selecting and Applying Tools,” which comes highly recommended for those investigating the various LCA packaging-specific tools available. You can find this resource via the following reference information:

Selecting and Applying Tools, Karli Verghese & Simon Lockrey, Pages 251-283, in Packaging for Sustainability, Editors: Karli Verghese, Helen Lewis, Leanne Fitzpatrick, ISBN: 978-0-85729-987-1 (Print) 978-0-85729-988-8 (Online).

Also, as explained during her presentation at Sustainability in Packaging, she authored the book “Packaging for Sustainability,” to be published in April 2012 and available at www.springer.com.

Ok so I am trying to do the best job describing the insights outlined in Verghese’s presentation BUT please note that she spoke quickly and my fingers can only type notes so fast!

Verghese began explaining how the conversation about packaging sustainability has evolved from a materials focus (material A vs. B) to a systems focus, where the interaction between the product and packaging in a supply chain system becomes paramount. She qualified this statement with reference to several examples, the first of which, an Australian study that investigated the environmental impact of corn chips. Verghese inquired "Is it the corn chips or the bag (400 gram packets of corn chops, aluminum foil retail bag, corrugated box)"?

The study determined that the environmental impacts in CO2 equivalents are as follows:

Life cycle stage 1, pre-farm= 6%
Life cycle stage 2, on-farm= 36%
Life cycle stage 3, post-farm= 58%

Within this analysis, packaging accounts for 21% of overall systems environmental impacts; supply chain transport accounts for 9%.

Verghese’s next example inquired, “Is it the wine or the bottle?” By reference to another LCA-base study, Verghese demonstrated that the environmental “hot spot” was during the production of grapes for the wine i.e. viniculture.

These types of analysis supported Verghese’s assumption that a systems approach to packaging sustainability is favorable to the previous materials-focus i.e. paper vs. plastic.

Verghese then moved onto a discussion about how to select the “right” packaging assessment tool, based on a variety of considerations stemming from one’s business and sustainability strategy(s) and packaging sustainability policy.

Because the insights to follow via Verghese’s presentation were SO valuable, I decided to compile them—- in addition to those previously discussed in the panel session—- into a Report that should aid interested parties in understanding the available tools for assessing packaging sustainability; and, provide guidance for how to select the “right” tool based on one’s specific business question.

How to Assess Sustainable Packaging

My next post will discuss a recent UC Berkely study that compares the data out puts of the various LCA packaging specific tools.

Happy Monday Funday! I hope everyone had a nice weekend and one full of relaxation!

As most industry-folk know, the Global Packaging Project released its “A Global Language for Packaging and Sustainability: A framework and a measurement system for our industry” a week ago-ish, which discusses, as the title implies, a global metric for assessing the sustainability of a given package or packaging system. Pack World’s/Greenerpackage.com’s Anne Marie Mohan provides a good summary of the project here with the report(s) available for download: http://www.greenerpackage.com/metrics_standards_and_lca/gpp_releases_global_framework_measurement_system_sustainability.

As Mohan explains, the GPP looks to create a GLOBAL metric for quantifying the “sustainability” of a package/packaging system. While the Walmart Scorecard and the SPC’s Metrics for Sustainable Packaging exist in isolation, this project looks to be the over-arching governance on sustainable packaging metrics, absorbing the work of both the SPC and Walmart. From what I believe, if a new metric wishes to be added to the Walmart Scorecard, it must first be presented to the GPP for consideration and validation.

For those of you unfamiliar with the concept of “sustainable packaging metrics,” a “metric” can be understood as an “attribute” that a given package or packaging system has in the context of the environment from a life cycle approach. For instance, packaging weight could be a metric taken into consideration when trying to quantify the environmental profile of a given package, as is the case with the SPC’s COMPASS packaging life cycle assessment modeling software and the Walmart Scorecard (packaging weight informs the energy required to transport the product/package throughout the supply chain and consequentially impacts GHG emissions, fossil fuel consumption, etc.)

Unlike the Scorecard and COMPASS, however, this global set of metrics takes into account social and economic indicators, in addition to the environmental ones; in my opinion, this integration makes the GPP’s approach to assessing packaging sustainability a much more holistic and therefore efficient tool than those currently in use.

Taken together, the GPP proposes 52 metrics that need to be recognized in the discussion around issues pertaining to packaging and sustainability. 52, isn’t that wonderful!!!

And here are some of my favorites:

Environmental—chain of custody: This questions if the production/cultivation of the feedstock (cellulous vs. fossil fuel) is done so “sustainably.” Think Forest Stewardship Council…AWSOME!

Environmental—water used from stressed sources: This metric questions where the water comes from that facilitates the production/cultivation of the packaging feedstock. Check out the Global Water Tool, based on several independent sources, which provides a global water scarcity mapping function for the identification of production activities occurring in stressed or scarce watersheds:

There's this, too:

Economic—packaged product wastage: this metric questions the value of packaged product lost due to packaging failure. I like this one because it is so simple; it reaffirms the number one function of packaging, which is, to protect the product. In a time when “smaller product to package ratio”, “material reduction” and “downgauging” has become, for the most part, our industries’ approach to “sustainability,” it is nice to be reminded of the necessity for excess…

Social—community investment: This metric questions the role a corporation plays in its community. Because Corporate Social Responsibility reports are so in vogue, it’s nice to see that such efforts will be quantified with this assessment, hopefully influencing purchasing decisions.

For the other 49 metrics, check out the report here:

Ok folks, that’s all I got for today. I am researching how to perform a waste audit so we can determine what type of composter would be the most appropriate for Dordan’s food and yard waste generation. Details to come!
