Are plastics the most sustainable packaging choice?

Six major categories of plastic packaging significantly reduce energy use and greenhouse gas emissions compared to packaging made with alternative materials, according to a new study.

Compiled by Franklin Associates for the American Chemistry Council and the Canadian Plastics Industry Association, and using 2010 as a baseline year, the data shows replacing plastic packaging with alternative materials would result in a 4.5 times more packaging weight, an 80 percent increase in energy use and 130 percent more global warming potential.

“The benefits hold up across a range of different kinds of applications and materials,” said Keith Christman, managing director of plastics markets for ACC. “Because plastics use so much less material in the first place it results in dramatic greenhouse gas reduction, and that’s just the start. It really adds up across the different types of packaging, to the equivalent of taking more than15 million cars off the road.”

The study pits the six major packaging resins — low density polyethylene, high density PE, polypropylene, PVC, polystyrene, expanded PS, PET — against paper, glass, steel, aluminum, textiles, rubber, and cork. It considers the implications of the materials used in caps and closures, beverage containers, other rigid containers, shopping bags, shrink wrap, and other flexible packaging in a detailed life cycle assessment.

Individual studies on particular products have been done before, Christman said, on products ranging from plastic pouches vs. cans for tuna and EPS vs. paper cups. But the new study, titled Impact of Plastics Packaging on Life Cycle Energy Consumption and Greenhouse Gas Emissions in the United States and Canada, is comparatively sweeping.

It contains more than 50 tables and 16 charts and illustrations and examines each of the major life cycle stages for packaging: raw material production, packaging fabrication, distribution transport, post-consumer disposal and recycling.

The study also offers a glimpse into the potential unintended consequences of proposed and recently enacted bans on plastic packaging products, Christman said. While a plastic bottle ban might keep bottles out of waterways, the increase in energy use to manufacture, transport and even recycle their glass counterparts would be dramatic, according to the numbers.

“I don’t think that’s what people intend by some of those policies,” Christman said. “But it could happen if policies force people back to alternatives that use more energy and produce more greenhouse gas emissions.”

BioPlastics Dirty Little Secret

So you know all about bioplastics, Right? You know they are difficult to process, often cause more detriment to the environment than traditional plastics, have limited shelf stability and can be very expensive. But what you may not have known is…..

Nearly every plastic on the market today is a bioplastic! In todays market, when one uses the term “bioplastic” they typically beleive they are refering to a plastic that is sourced from plant materials. What most don’t realize (and many try to avoid admitting) is that most all plastics are made from plant materials!

When I was in elementary school, I had an amazing 4th grade teacher. Of the many things she taught me, one was that fossil fuels were the remains of dinasour bones. Little did my teacher realize the error of her ways. Fossil fuel is primarily comprised of ancient algae (YEP, PLANTS!). So any product made from fossil fuels, is made of……

Plants.

Now, don’t get me wrong; I am not advocating the use of fossil fuels. Quite to the contrary, it is imperitive that we get away from the use of the ancient plants as quickly as possible. These plants have sequestered carbon for millions of years. Carbon that if released into our atmosphere could cause irrepairable damage.

What I am advocating is to educate properly, get rid of the fluff and marketing and call things as they are. The source is not the issue, it is the environmental impact of the source that is the issue. Perhaps we need to identify plastics as “sustainable” or “not sustainable” and leave it at that. Because you either are or your not, it’s that simple.

Corn Lobbyists don’t get the final word

California’s governor vetoed SB-1454 despite its intent to clarify misleading labeling

The recent demise in California of legislative bill SB-1454 took some by surprise. This cleverly written piece of legislation was designed supposedly to clarify misleading labeling claims and would prevent the sale of plastics in California whose packaging is labeled not only biodegradable but also compostable.

One Step to Success

The other night I was helping my daughter with her math homework. She was frustrated and overwhelmed with the amount of problems and the difficulty level. After several hours of this, she stopped cold in her tracks. “I am not going to do this anymore, this is too hard, there are way too many problems and I don’t even know how to solve them! I might as well just quit.”

This reminds me of the many times I have felt this way myself with environmental issues –

  • Why do people litter?
  • Do I use paper, plastic or reusable bags? (I forgot my reusable bags again!)
  • Rain forests disappearing!
  • Ice caps melting!
  • Global warming!
  • Plastic water bottles
  • Driving my car!
  • The issues can sometimes seem endless and a bit overwhelming if we try to tackle everything. Sometimes I too feel like stomping my feet and giving up.

    So, back to the math lesson; what happened? I covered up every math problem except one and we began to work one problem at a time. Even breaking the problems down to the individual components when a problem seemed difficult. About 30 minutes later, the lesson was complete and my eight year old stated “Once I stopped looking at the whole thing, it was easy.”

    So let’s all take the advice of an eight year old and stop worrying about every environmental issue out there. Pick one simple thing and make a start – One Step to Success! (I am going to turn off the lights when I leave, how about you?)
