A method for recycling of glass laminates (10) is disclosed. The glass laminates (10) comprise at least one glass layer (30, 40) and at least one polymer layer (20). The method comprises mechanical removal of at least part of the glass (30, 40), placing residual waste (350) with glass particles in a vat (360) comprising a separation fluid (375) to produce a mixture of glass particles and polymer pieces from the residual waste, from which the polymer pieces can be screened off, washed and dried for reuse. The separation fluid (375) comprises water and at least one alcohol.

The invention provides automated spacer processing systems and methods. The systems and methods involve at least one robot arm that is configured to process spacers for multiple-pane insulating glazing units. In some embodiments, the systems also include an insulating glazing unit assembly line and a spacer conveyor system. Additionally or alternatively, the systems may include a sealant applicator.

Processes are disclosed for separating a first layer from a remainder of a tapered multilayer interlayer sheet, in which the tapered multilayer interlayer sheet is heated, and thereafter the first layer is separated from the remainder of the tapered multilayer interlayer sheet by pulling the first layer and the remainder of the tapered multilayer interlayer sheet in different directions, in a defined orientation, without the tapered multilayer interlayer sheet wrinkling or tearing.
