What was done

This integrative narrative review synthesized literature on global plastic production and waste data, assessed the sustainability of bio-based biodegradable plastic alternatives, and evaluated waste management policy strategies.

What was found

Global cumulative plastic production increased from approximately 2 million tonnes in 1950 to 8.3 billion tonnes in 2015, generating 6.3 billion tonnes (76%) of waste, 79% of which went to landfills or into the environment. The review reported that biodegradable plastics are not universally environmentally superior to fossil-based plastics, investment in waste management lags behind production, and policy frameworks such as extended producer responsibility and deposit refund schemes have demonstrated effectiveness in Australia, France, Germany, and Ecuador.

Why it matters

Bio-based biodegradable plastics cannot solve plastic pollution in isolation without targeted regulatory mechanisms and major investment in waste management infrastructure.

Limits
