A patent intelligence analysis aimed at identifying eco-friendly methodologies for recycling PVB to be used as windscreens interlayer
Identification of methodologies for recycling laminated glass, especially the interlayer film, and their contextualization within the glass recycling field implicated an extensive patent search. During the last decade the technology centre L'Urederra exploited a methodology for recycling the poly-vinyl-butyral to be reused as interlayer in windscreens. Subsequent rounds of patents selection were aimed at identifying equivalent or innovative methodologies.
