Cardia subsidiary aims for PPC boost

CO2 Starch Pty Ltd said the aim of the partnership is to produce alternative renewable biodegradable plastics at an economical price while maintaining good mechanical properties that meet international compostability standards.

Poly (propylene carbonate) (PPC) is a biodegradable aliphatic polyester which is synthesized from copolymerization of carbon dioxide (CO₂​) and polypropylene Oxide (PO).

Pat Volpe, CO₂​ Starch Pty chairman, said: “In collaboration with the University of Sydney, CO2Starch Pty Ltd is looking to expand its patented PPC +starch blending technology into application with in the packaging industry before addressing potential applications in other industries including but not limited to the medical industry.”​

“We are working with the University Of Sydney to develop and adopt their new unique technique that aims to produce PPC in a one step manufacturing process (rather than two) that also lower the levels of residual zinc catalyst and potentially lowers the costs of PPC.”​
