Last week, we posted a piece on bioplastics and the problems that arise from improper disposal of bioplastic and plastic products. Primarily, we touched on the misconceptions regarding labelling. Labels are sometimes misleading and the terminology used is often confusing. We love that so many clients and customers are coming to us looking for sustainable alternatives to common materials like plastic. That’s why we want to further explore the differences between degradable, biodegradable and compostable to better manage waste and to make the most of these eco-friendly options.
The Environment and Plastic Industry Council states that the term “degradable” broadly implies that the product will break down into smaller pieces naturally, over a (vague) period of time. “Biodegradable” is the process that takes place after degradation, when the particles are consumed by micro-organisms, resulting in water, carbon dioxide or organic matter.
“Compostable”, meanwhile, refers to degradable materials that—under proper commercial or home composting conditions—turn into usable compost or humus that enriches the soil and returns nutrients to the earth. These products leave no toxic waste behind and the process takes between 90 to 180 days.
So, how do you actually dispose of these products properly?
As we mentioned in last week’s post, most municipalities in Canada and the US still lack the proper means to compost and recycle. Between that and misleading terms, well-intentioned customers are becoming frustrated.
With the help of some wonderful sources, including the Green Office, we’d like to clear some things up:
- Compostable products must be disposed of in a proper industrial composting facility. If such facility is not available, these products can be disposed of in the backyard or in a home composter, though it will take longer for the products to fully disintegrate. Improper disposal of compostable products in the recycling bin will actually contaminate the recycling process.
- Biodegradable products are most often thrown in the garbage. While this should theoretically be okay as these materials are thought to just “break down”, it’s really not. Landfills are basically built to entomb waste and therefore lack the microorganisms and oxygen to break down these materials in a timely manner. Until there are proper processing facilities for biodegradable materials—like in California and Washington—these materials should be disposed of through a composting facility. But again, with the green bin program only just taking off in major cities, most municipalities make it next to impossible to properly and efficiently dispose of biodegradable products.
- Recyclables should always be disposed of through the municipal curbside garbage program—those blue bins that are handily available almost everywhere. If there is no access to these programs or blue bins, services like Earth911.org help locate drop-off locations.
As customers are becoming more inclined to choose products that are environmentally-friendly, eco-conscious consumerism has become a hot button for advertisers. While the Federal Trades Commission’s Green Guide regulates how companies can use the terms “degradable,” “biodegradable” and “compostable,” customers are still advised to beware of “greenwashing.” This is when companies deliberately lead consumers to think their brand is “green”, without actually being so. The next generation of green products can also be labelled oxo-biodegradable, hydro-biodegradable, photo-biodegradable or water soluble. With more and more terms being thrown into the game, companies are getting away with branding their products improperly—or even just making up terms that sound eco-friendly.
Recent amends to the Federal Trades Commission’s Green Guide and the Canadian Standards Association and Competition Bureau have tightened regulations on companies using these terms and require that environmental claims be made clear, specific and verified. Any claims made must now be backed up with evidence.
But, as with everything, it is up to the customer to use discretion when buying—and to always read labels correctly and to use and dispose properly. And let’s not forget that waste—any waste—should be reduced. Cutting back the purchase of one-time-use products and reusing or repurposing is always the best choice when thinking green.
