The transformation towards a genuine circular economy in the construction industry requires that materials and products can be evaluated after use and, if necessary, reused in whole or in part. Laminated safety glass (LSG) consists of glass panes with plastic films in between and is used, among other things, for overhead glazing, balustrades and windshields.

Currently, laminated safety glass elements are usually crushed after their life. Direct reuse does not usually take place, as there are no criteria for deciding which laminated safety glass panes still have sufficient durability and composite effect.
