Every year, millions of damaged automotive windshields end up in landfills. Discover how modern mechanical-chemical delamination recovers 93% glass and 7% high-value PVB polymer.
Automotive windshields and architectural laminated glass pose a unique environmental challenge: because two sheets of glass are permanently bonded with a tough PolyVinyl Butyral (PVB) interlayer, conventional glass crushers cannot process them. For decades, millions of windshields were condemned to landfills, taking centuries to degrade.
Aavishkar Recycling LLP has pioneered a closed-loop recycling model in India. Using patented mechanical-chemical separation technology, damaged windshields are de-laminated cleanly into:
1. High-Purity Glass Cullet (92%–93% yield): Direct raw material for tinted float building glass, container glass, and glass wool insulation.
2. Reclaimed PVB Polymer (6%–7% yield): Purified and compounded into footwear masterbatches, anti-corrosive primers, and automotive floor mats.
This circular loop not only avoids thousands of tons of landfill waste each month, but also saves up to 25% energy in glass furnaces and provides cost-effective polymer alternatives for industrial manufacturers.
