Kaust, a Saudi Arabian university and research centre, has decided to work closely with two Chinese companies, Shandong Lianxin Environmental Protection Technology and Hangzhou Hecai Technology, to produce green plastics for biomedical products and food packaging from high-molecular-mass aliphatic polycarbonates that favour certain aspects that have become essential for the environment, such as high biodegradability, low toxicity and excellent biocompatibility.
