 Due to its biodegradability and potential to create bioplastics with novel properties, much interest exists to develop the use of PHA-based materials.PHA fits into the green economy as a means to create plastics from non-fossil fuel sources.Furthermore, active research is being carried out for the biotransformation "upcycling" of plastic waste (e.g., polyethylene terephthalate and polyurethane) into PHA using "Pseudomonas putida" bacteria.
