Ecolar, jointly incubated by PolyU and Science Park, has developed a series of green and safe antibacterial materials based on polyhydroxyalkylate (PHA), which can be applied in the medical and health field. Zhang Ziheng, CEO of Ecolar, said that participating in overseas forums allows the company to showcase advanced technologies and products, while learning about Europe’s cutting-edge research and transformation systems for scientific and technological achievements.
