Is it true that conventional petroleum-based plastics are biodegradable?
No. Multiple peer-reviewed and reference sources state that conventional petroleum-based plastics are non-biodegradable and persist for hundreds of years, while presenting biodegradable polymers as alternatives to them. Two items directly assert conventional plastics are non-biodegradable or take hundreds of years to degrade.
