摘要

Identification of methodologies for recycling laminated glass, especially the interlayer film, and their contex-tualization 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. Few documents address the recycling of the poly-vinyl-butyral film describing a stage implicating a mechanic separation followed by a basic solution treatment. According to a recent journal article, such stages combination is crucial for obtaining recycled PVB compatible with its reincorporation in windscreens.
