Recycled PVB from Windscreens to Carpet

2015-06-11 09:00:00 +0100 by


There are over one billion cars in the world, and an average of 5-6% gets a new window every year.  Working with partners, Interface, the world's largest carpet tile manufacturer, are turning he PVB from broken windscreens into a useful component for their carpet tiles.

The EU is pushing for recycling of windscreens, but the laminate material (PVB) that prevents the windows from shattering has not been given a second life, until recently.

Interface has partnered with the supply chain to process the laminate and use it in the production of carpet tiles. This means they are able to reduce the carbon footprint of their carpet tiles and extend the useful life of PVB at the same time.

Interface has a history of radical innovation. In 1994 they started Mission Zero®, a commitment to become, by 2020, the first company to be fully sustainable. This means that by 2020 their aim is that all their raw materials must be 100% recycled or biobased.

Car windows have been laminated to prevent shattering since the 1930s, and every year one in twenty cars has a window replaced. This generates a stream of material ensuring a plentiful supply worldwide.

Most car windows are laminated using Poly Vinyl Butral (PVB), a material that can be used as a replacement for latex, the traditional material used as a carpet precoat.

"Using recycled PVB reduces the carbon footprint of the precoat by 80% compared to traditional latex." Interface

With global headquarters in Atlanta, Interface Inc. has approximately 4,000 associates today with manufacturing facilities in  LaGrange, Georgia and West Point, Georgia in the United States, as well as in the Netherlands, theUnited Kingdom, Australia, China and Thailand.
