CEN Workshop on characterizing polyvinyl butyral (PVB) recyclates
Laminated glass is obtained by bonding glass layers using a polymeric interlayer. One polymer used as interlayer is polyvinyl butyral (PVB). Up to now, most of the post-consumer PVB material in laminated glass is incinerated or landfilled, and only 9 % are recycled in secondary uses. Recycling of PVB presents several difficulties related with the contents of glass, humidity, mixing of compositions and polymer optical degradation.
