Discarded PS can be converted to biodegradable plastic for use in the medical field

Researchers at the National University of Ireland and the University of Hamburg in Hamburg recently developed a new process for converting waste polystyrene into biodegradable plastics.

The technology first pyrolysis of polystyrene to styrene oil, and then use bacteria to convert the oil to polyhydroxyalkanoate (PHA) biodegradable polymer, this PHA can be applied to plastic coatings and pressure sensitive adhesives Can also be used in the medical field. The use of the bacteria Pseudomonasputida CA-3 is said to be the key to success, and this finding has been published in the journal Environmental Science and Technology.
