Automotive Waste Windshield Recycling Line Process Explained

Waste automotive windshields are laminated glass, typically consisting of two glass layers bonded with a PVB (Polyvinyl Butyral) interlayer. Recovering clean glass from this material requires more than conventional crushing and screening. The key challenge is separating glass fragments that remain attached to the PVB film while minimizing the loss of recoverable glass.

Our 8–10 TPH waste windshield recycling line is designed for high-volume processing of end-of-life automotive windshields. The system integrates a glass pre-pressing machine, feeding hopper, conveyor, trommel screen, glass-PVB separation machine, and double-layer optical color sorter to process laminated glass and recover glass cullet and PVB film.

After pre-pressing, the material is transferred through the feeding system to the trommel screen. The screen separates loose glass fragments (Glass A) from the remaining material containing PVB film and attached glass. The latter enters the glass separation machine, where further separation produces additional glass fragments (Glass B) and recovered PVB film. The plant then combines both glass streams for further processing. The combined glass material passes through a double-layer optical color sorter, which identifies and separates light-colored glass from dark-colored glass and other unwanted materials. This additional sorting stage helps improve the consistency and quality of the recovered glass cullet.

With a processing capacity of 8–10 tons per hour, this industrial windshield recycling plant is designed for large-scale laminated glass recovery.
