Disappeared waste plastic bottles successfully developed in the United States
According to the report of the American Daily Science website on April 28, the research team of the Missouri University of Science and Technology is currently developing a new biodegradable plastic polyethylene lactic acid to reduce the amount of plastic waste that has to be disposed of by landfills each year. .
Every year, more than 30 billion plastic bottles are added to the garbage in the United States, causing huge environmental problems. But if a study by the University of Missouri Science and Technology in the United States succeeds, the new plastic bottles of the future will automatically disappear within four months after being discarded.
This new type of material is fundamentally different from the plastics currently being used in large numbers. The main component of plastics is polyvinyl chloride derived from petroleum. This kind of polyvinyl chloride, which is difficult to be naturally decomposed, is the main cause of plastic pollution.
Experts at the Missouri University of Technology are considering how to choose bio-based fillers, such as adding starch and fiber to their products, and minimizing costs in various business applications.
Dr. Saharah, Ph.D., of the University of Missouri Research Center, said: “Polyethylene lactic acid, a new plastic component, will be decomposed within 45 to 60 days if it is placed in a slightly warmer natural environment. After being decomposed, this material then reacts with water and breaks down into small molecules, which then dissolve into minerals or become carbon dioxide in water. It is estimated that in the natural state, the entire decomposition process of plastic bottles can be completed within 4 months. carry out."
Sahala concluded: “The new type of plastic bottle with polyethylene lactic acid as its main ingredient completely replaces the potential for water bottles.†Please indicate the source:
