Are biodegradable plastics a promising solution to solve the global plastic pollution?

Area of Science:

• Environmental Science
• Materials Science
• Polymer Chemistry

Background:

• Global plastic waste accumulation causes significant environmental pollution, termed 'white pollution'.
• Weathering degrades plastics into harmful microplastics and nanoplastics, exacerbating environmental and human health risks.
• Conventional plastic production and disposal methods necessitate urgent reevaluation.

Purpose of the Study:

• To critically assess the viability of biodegradable plastics (BPs) as a comprehensive solution to global plastic pollution.
• To examine the limitations and potential of BPs in managing plastic waste accumulation.
• To discuss the factors influencing the successful implementation and effectiveness of BPs.

Main Methods:

• Review and analysis of current research on biodegradable plastics.
• Discussion of the environmental conditions required for BP biodegradation.
• Examination of the interplay between technological solutions, waste management infrastructure, and human behavior.

Main Results:

• Biodegradable plastics (BPs) cannot fully replace conventional plastics due to limitations in biodegradability under diverse environmental conditions.
• The effectiveness of BPs is contingent upon reliable environmental conditions and is not a standalone solution.
• Human behavioral awareness and effective waste management systems are crucial for successful BP implementation.

Conclusions:

• Biodegradable plastics (BPs) are a potential component of plastic waste management strategies but not a complete solution.
• Successful environmental solutions require integrating BPs with advanced waste classification technologies and organic waste treatment facilities.
• Significant advancements in infrastructure and a shift in public responsibility are necessary to address global plastic pollution effectively.
