Anti-plastic claims analyzed

Written by Chandler Slavin | Oct 16, 2012 4:04:00 PM

Hey!

So in yesterday's post I talked about an article I read on greenerpackage.com that dissapointed me due to its unfounded anti-plastic stance. I? included a letter that I had intended on sending to the disseminator of said anti-plastic stance because I didnt want to call him out in the public forum that is greenerpackage.com; however, our CEO wanted me to post a rebuttal to his comments on greenerpackage.com, so this reductionistic stance on plastic can begin to be confronted.

Here we go:

After reading the above article titled “Paper media packaging for Kodak licensee removes 98% of plastic,” I believe that KMG Digital’s Mike Golacinski may be misinformed. Speaking on behalf of a plastic thermoformer, we are disappointed when we stumble across the proclamation of misinformed or unsubstantiated environmental claims about plastic packaging. Therefore, I would like to take this opportunity to analyze these anti-plastic environmental claims with hopes of facilitating an honest dialogue about packaging materials and sustainability. Only when we understand the reality of the situation will we begin to make more informed packaging material procurement selections that are based on science, and not ambiguous claims.


Consider the following statement: “Many competitive products are boasting about reduction of plastics while not addressing the fundamental issue, which is to eliminate plastic packaging that produces greenhouse gases and clogs our landfills…”

First of all, the assumption that plastic packaging produces greenhouse gases is misplaced. Almost every product and service produces GHG equivalents during production and throughout the life cycle. Let’s clarify what “greenhouse gases” mean:

According to the 2009 report released by the U.S. Global Change Research Program, the largest factor contributing to global warming is increased greenhouse gas emissions such as carbon dioxide, methane, nitrous oxide, water vapor, halocarbons, and soot. Therefore, when making claims of GHG emissions, it is helpful to indicate which chemical you are referring to, as each packaging material procurement and conversion process releases different GHG equivalents, based on the methods used.

In addition, not only should GHG equivalents generated be consideration when procuring packaging materials, but other metrics, like water discharges, air pollutants, and OSHA carcinogens should be taken into account.

While I have not been able to find the necessary data to do an apples-to-apples comparison between the GHG equivalents emitted during the production of 1,000 lbs of fiber-based packaging materials versus those emitted during the production of 1,000 lbs of a common packaging polymer, the most recent Toxics Release Inventory data released by the U.S. E.P.A. explains the following:

…Pulping processes are the pulp and paper sector’s primary source of air emissions and water discharges of pollutants. Chemical pulping (to digest a material, typically wood, into its fibrous cellulose constituents) is the most widely used pulping method (85% in 1991). Kraft chemical pulping, an alkaline process whose active components are primarily sodium sulfide and sodium hydroxide, is the sector’s greatest source of air pollutants.

…For many paper grades, bleaching follows pulping. Traditional chlorine bleaching generates chlorinated byproducts—chloroform, dioxins, furans—that pose particular environmental concerns for their persistence, bioaccumulatability, and toxicity.

…Methanol or “wood alcohol,” is the chemical with the largest TRI releases (principally air emissions) from this sector. Methanol is formed in the chemical pulping process as wood chips are “cooked” to dissolve the lignin bonds that hold cellulose fibers together…Methanol in air reacts to form formaldehyde, contributing to air pollution…119.8 million pounds of methanol were released from the pulp and paper sector in 1996.

…Coated and laminated paper products are also associated with significant reporting of releases and other waste management of TRI chemicals…Pollutants associated with various coating materials and processes have included emissions of volatile organic compounds (VOCs) and discharges of wastewater containing solvents, colorants, and other contaminants.

…Pulp and paper releases…of chemicals designated as OSHA carcinogens totaled 18.9 million pounds in 1996. The large majority (17.7 million pounds) was released to air. Three of the top 15 chemicals for on- and off-site releases in the pulp and paper sector are OSHA carcinogens: chloroform, acetaldehyde, and formaldehyde. These three chemicals accounted for 16.4 million pounds of the 18.9 million pounds of OSHA. The OSHA carcinogens with the next highest on- and off-site releases were dichloromethane (746,000 pounds) and asbestos (571,000 pounds).

…[In summary,] The pulp and paper sector reported a total of 1.60 billion pounds of TRI chemicals in production-related waste for 1996

Second, the assumption that plastic packaging “clogs our landfills” is also misinformed: According to the Container and Packaging Municipal Solid Waste data released by the U.S. E.P.A. in 2007, 52% of landfills are comprised of paper products. In addition, in the MSW report released in 2008, “paper packaging/other paper packaging” has no recovery data (“Neg.”), which implies that paper packaging does not often get recycled, contrary to popular belief. Please visit: http://www.epa.gov/epawaste/nonhaz/municipal/pubs/msw2008data.pdf. On page 5 of this document you will find a break-down of the different paper products that are recycling in America: as this table illustrates, the high recovery rates for paper are attributed primarily to newspapers (87.6% recovery) and corrugated boxes (76.6%).

I apologize if the tone of this post is a bit aggressive; I am not trying to make anyone uncomfortable I just wanted to take advantage of this public knowledge exchange medium with hopes of elevating the dialogue around issues pertaining to packaging materials and sustainability. While there is a lot of confusion surrounding the sustainability of plastic packaging, I am confident that the science will catch up, the dialogues will evolve, and packaging professionals will begin making more informed packaging decisions based on sound science and not marketing claims.

In a nut shell: The anti-plastic mentality conveyed in the statements made by representatives of KMG Digital is unfounded in the scientific community and to use it to promote paper over plastics is not good for any company involved in packaging from an economic, social, political, and environmental perspective.

So yeah...that's that. Questions, commments, concerns?

AND I am about half-way finished with my report on PET recycling for Walmart Canada--it is about 6 pages; my brain is about to explode!

See you tomorrow!
