Advancing Electronic Waste Mitigation Using Vitrimer-Based Printed Circuit Board

Authors- Prasanth M, Professor DR.K. Nandhini

Abstract-– This project is about creating and applying a novel printed circuit board (PCB) that will minimize electronic waste. PCBs are not easy to recycle because of their fiberglass substrate, which is composed of woven glass fibers and epoxy resin. Researchers at the University of Washington have come up with a solution through the substitution of epoxy resin with a vitrimer polymer. This material retains the PCB’s shape and insulating properties under use but becomes gelatinous when subjected to a low-boiling-point organic solvent at the end of its life cycle. This facilitates the simple removal of intact glass fibers and electronic components. Surprisingly, 98% of the vitrimer and 91% of the solvent can be recovered and reused. These vPCBs are compatible with current manufacturing processes and are recyclable several times. Research indicates that recycling vPCBs can reduce global warming potential by 48% and carcinogenic emissions by 81% in comparison to traditional PCBs. The project ensures sustainability in electronic manufacturing via a scalable, green method that saves precious components and reduces waste. By embracing this technology, the electronics sector can greatly reduce its ecological impact, promoting additional innovation in electronic recycling and resource preservation globally.
