Laminated Glass Recycling Solution for Glass and PVB Film Separation

Laminated glass is widely used in automotive windshields, architectural safety glass, and other applications requiring impact resistance and safety performance. It consists of two or more layers of glass bonded by a polymer interlayer, typically PVB (Polyvinyl Butyral), EVA, or SGP, under heat and pressure. While this structure improves safety and durability, it also creates challenges when recycling production scrap or end-of-life laminated glass.

For manufacturers and recyclers looking to recover reusable glass and PVB film, a dedicated laminated glass recycling system provides an efficient mechanical separation solution. The laminated glass recycling equipment is suitable for a wide range of laminated glass materials, including automotive windshields, architectural laminated glass, safety glass panels, and manufacturing off-cuts. The recycling process begins with controlled crushing and pre-treatment of the laminated glass. Rather than excessively pulverizing the material, the system uses optimized crushing technology to break the glass while preserving the interlayer’s integrity.

After pre-crushing, the material enters the separation unit, where mechanical kneading and roller-based delamination gradually detach the glass fragments from the bonded film layer. The separated materials are then processed through a screening system that classifies glass particles and polymer film. Clean glass cullet is collected for reuse in glass manufacturing or other industrial applications, while the recovered PVB film can be recycled further or processed according to market requirements.

For materials with particularly strong adhesion, an optional soaking stage can be incorporated before separation. By softening the bond between glass and PVB, this process can improve separation efficiency and enhance the quality of the recovered film. A complete laminated glass recycling line typically includes a pre-crushing machine, PVB glass separator, screening and conveying systems, and a dust collection unit. Operating as a continuous mechanical process, the system minimizes labor requirements while maintaining a clean and safe working environment.
