What Is R-PVB (recycled PVB)?

Recycled PVB (Polyvinyl Butyral) – Recycling from abandoned windshields and glass.


The overall objective is to help find a practical and sustainable use for waste glass from vehicles.


Background and environmental issues:
The main source of recycled PVB is windshield of abandoned car.
Each abandoned car could yield PVB 2.6kgs.
By estimating the output of cars, there could be waste PVB for more than 16,000 tons per month wide. As such we devote ourselves to develop recycled PVB and convert waste into valuable merchandise.


The Problem with Recycling Windshields:
Windshields are not commonly recycled because they are made from laminated glass, comprising two sheets of glass with a clear resin interlay called polyvinyl butyral (PVB).
With glass recycling technology, collected laminated glass is put through a crusher to separate the glass from the PVB.
We recycle PVB waste from the glass lamination process: automobile windshields, architectural glass/ windows, and acoustical glass applications.
