Eco-Packaging Solutions in Canada

I recently did some research on the various forms of eco-packaging to determine which option has the strongest environmental benefit; both in the manufacturing and disposal stage.

I looked at three options: compostable, PLA and recycled PET (RPET). I’ve provided a brief outline of the three options below.

Compostable packaging is the most commonly known eco packaging- largely because of the compostable SunChips bag.  In order to receive the compostable packaging claim, the pack must be able to break down within a specified period of time in an industrial facility. I was not able to determine the specified period of time, but Sunchips takes about 14 weeks to break down which is a good benchmark. However, the major downfall of compostable packaging is it requires an industrial facility to be broken down; you can’t throw the compostable pack in your backyard. Further, compostable packaging isn’t currently accepted by green bin programs in Canada. Therefore, products like Sunchips end up sitting in a landfill where they may not even biodegrade.  However, this may change as companies lobby municipalities to accept compostable packaging.

PLA packaging is made from renewable resources. It’s is typically made from corn, but it can also be produced using other resources like sugarcane and switchgrass. PLA’s greatest strength is that it’s made from renewable resources. However, there are ethical implications. PLA packaging drives up the demand for corn which causes a significant increase in commodity prices. This detrimentally impacts developing nations who consume corn in their daily life.

Last, but certainly not least is Recycled PET. PET is the most common form of packaging and is often found in bottles and jars.  Recycled PET is in my opinion, the best option as reuses plastic that would otherwise go to a landfill. Further, there is an established market for RPET since there is an abundance of PET plastic. Since both PLA and compostable packaging are made from renewable resources, the availability of supply is often a concern (if there is a drought or other natural disasters the price of packaging rises and you may not have enough supply).
