Due to strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility polyvinyl butyral(PVB) resin films are commonly used in the automotive and architectural application as a protective interlayer in the laminated glass. Worldwide million tons of PVB waste generated from end-of-life automotive associated with various environmental issues. Stringent environmental directive, higher land costs eliminate landfilling option, need a sustainable, environment-friendly technology to recycle these solid wastes. In our current study, we have developed a mechano-chemical separation process to separate PVB resins from glass and have characterized the separated PVB through various techniques, i.e., scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), infrared spectroscopy (IR) and nuclear magnetic resonance spectroscopy (NMR). Feasibility for reuse of these recycled PVB has been investigated. The technology developed in our laboratory is sustainable, environment-friendly, techno-economical feasible process, and capable of mass production (recycling).
