Enabling an Ecosystem for Recycling Waste Polarizers

Description:

This paper demonstrates the complete waste polarizer recycling and upcycling ecosystem designed by ITRI. Thousands of tons of discarded polarizers have been transformed into usable and valuable potential products, rather than being landfilled or poisoning the planet. In this paper, ITRI’s green recycling ecosystem for waste polarizer processing will be introduced. Over the years, ITRI has developed a series of green and efficient technologies, including a unique aqueous deiodination agent, and precise polymer mixture separation technologies for r-PVA. Additionally, several very promising upcycling applications of r-PVA and r-TAC were proposed.
