What does biodegradable really mean?
“Biodegradable” has long been a staple of the green movement. We know
to look for it on product labels because it’s good, both in the
packaging and the product, but do we really understand what it means?
For the most part, no. Unfortunately, it is one of the most commonly
abused greenwash terms, likely because there is no standardized
definition. Generally it means that the product will break down quickly
in nature to naturally occurring components with the help of the
existing bacteria. But how quick is quickly?
Eco-Logo, the most prevalent environmental certification in Canada
requires that products or packaging be “readily biodegradable”. They
specify a test for all products that measures how quickly a product
breaks down. In general they are looking for at least 60-70% breakdown
within 14 days.
This test is going to screen out a lot of products. Take plastic bags
for example. Technically they do biodegrade - they break down in nature
– it just takes an estimated 1000 years to do it (we don’t know for sure
since plastic bags have only been around for 50 years…). I don’t know
about you – but that’s not my idea of biodegradable.
