Renewable Resource and Biodegradable Polymers

Biodegradable plastics are made out of ingredients that can be metabolized by naturally occurring microorganisms in the environment. Some petroleum-based plastics will biodegrade eventually, but that process usually takes a very long time and contributes to global warming through the release of carbon dioxide.

Petroleum-based plastic is derived from oil, a limited resource. The plastic present in renewable raw materials biodegrades much faster and can be almost carbon neutral. Renewable plastic is derived from natural plant products such as corn, oats, wood, or other plants, which helps ensure the sustainability of the earth. Polylactic acid (PLA) is the most widely researched and used 100% biodegradable plastic packaging polymer currently, and is made entirely from corn-based cornstarch.
