Biodegradation
What is Biodegradation?
Biodegradation is not merely the physical breakdown of plastic through mechanical processes; rather, it involves the action of microorganisms breaking down plastic molecules to the molecular level. Ultimately, this process leads to the conversion of plastic into carbon dioxide (CO₂) and water (H₂O), allowing it to circulate back into the natural environment.
Characteristics of Biodegradable Plastics
The use of biodegradable plastics is expected to streamline waste management and reduce marine plastic pollution.
