HOW IS IT POSSIBLE TO EXTRACT PVB FROM FLAT GLASS WASTE OR AUTOMOTIVE WINDSCREENS AND RECYCLE IT FOR MANUFACTURING BITUMINOUS BINDERS FOR USE IN ROOFING MEMBRANES OR FUNCTIONAL COATINGS?

GreenWin presents REBINDER :

Polyvinyl butyral (PVB) is a thermoplastic which is chiefly used in the manufacturing of
security glass and windscreens. At the present time it is a plastic that is not recycled
in Wallonia. However, the annual mass of potentially recyclable PVB is estimated at
around 10, 000 tons in Belgium.

The REBINDER project aims to establish and perfect a process for the extrusion of PVB
from flat glass or automotive glass waste in order to enable its recycling and qualitative
refinement.

It is also looking at developing new high value-added industrial applications that
can utilise this PVB recyclate in the manufacturing of bitumous binders for roofing
membranes and in the formulation of functional coatings.

Les « + » :

Better understanding and improvement of the PVB recycling process.
Reduction in the quantity of buried plastic.
Optimisation of 20% of glass recovered: economic added value.
