How can I easily tell which plastics are Biodegradable and which are not?
Biodegradable plastics will oftentimes be labeled as such if they are for consumer use. As an example, a biodegradable plastic cups at a restaurant will often be labeled as such, mostly for marketing purposes so the restaurant can claim they are being environmentally friendly. The best bet, however, would be to try and find out the source of the plastic or an ingredients list. Biodegradable plastics are often made with plant-based ingredients instead of the more harmful chemicals contained in traditional plastics. But be wary of biodegradable plastics. They only biodegrade if they are disposed of in a specific way, i.e. composted properly. If you throw them in the trash can they will not biodegrade in a landfill.
