dc.description.abstract The study is focused on windshield recycling process resulting in poly(vinyl butyral) (PVB) sheets with very low amout of remain glass particles. PVB sheets were obtained from worldwide manufacturer DuPont and then they were laminated by standard autoclaving process. One sample of PVB sheet was modified by multi-functional organic acid in order to compare various levels of adhesion. Three-stage technology was proposed for recycling PVB sheets. In the first-stage laminated safety glass was mechanically cracked. In the second-stage the adhesion reduction to minimal degree was followed by chemical-physical assisted separation. It causes self-release of the glass out of the PVB sheet. The third-stage was mechanical peeling of the remaining glass from the PVB sheet which completed the recycling process. The optimal process conditions for the most effective delamination process were found. Delamination technology produces PVB sheet with minimal residual glass content (up to 300 ppm) and minimal change in PVB sheet properties. Described recycling technology is ecologically friendly (the effluent is fully recyclable as well) and could reduce the worldwide problem with windshield waste disposal. © 2013 Wiley Periodicals, Inc. en
