The global plastic stock has exceeded 8 billion tons, and the trend of increase has been increasing rapidly since the 2000s. Among them, packaging materials account for 47%, so it is urgent to develop alternative materials. It is reported that the global mask production due to COVID-19s has reached 52 billion, of which 1.5 billion are being thrown into the sea after use, amounting to between 4,680 and 6,240tonnes of plastic pollution. This presentation intends to introduce research on manufacturing methods for biodegradable bioplastics with strong physical properties and manufacturing biodegradable multi-mask filters using this material. |
