The present invention relates to a recycling process for a laminate and a solution used in such a process. The present invention finds particular application in the removal of an adhered overlay from an underlying substrate material such as plastic. The process includes subjecting the laminate to an impact frictional striking force, thereby substantially separating the substrate layer from the one or more surface layers of the overlay and then washing the substrate layer with a washing solution to remove the remaining surface layers of the overlay and glue from the substrate layer. The washing solution may be an aqueous solution including a surfactant, a solvent and a base.
