Biodegradability of bioplastic blown film in a marine environment

The waste created by single-use plastics is an important global issue, especially in marine environments, because they do not degrade nature. This work aimed to study the biodegradability of bioplastic blown film, which may pose a solution this problem. Polybutylene succinate (PBS) and polylactic acid (PLA) films were chosen for examination their when submerged sand under seawater floated on surface our experimental setup. Bioplastics observed comparison with low-density polyethylene (LDPE), petroleum-based plastic. PBS film exhibited faster degradation rate than PLA while LDPE did environment. was confirmed physical observation, change chemical functional group measured Fourier-transform infrared spectroscopy, test biochemical oxygen demand after due ingestion bacteria seawater.
