Abstract

A method for recycling of coated glass, especially for reuse in a glass melt, comprises the steps of crushing the glass; transferring the crushed glass into a mixing unit; mixing the crushed glass for a predetermined time period; during the mixing step, adding liquid to the crushed glass and cleaning the crushed glass with the liquid; and removing the cleaned crushed glass from the mixing unit. The method is especially useful for recycling cathode-ray tubes.
