The recycling task

Glass is a 100% recyclable product that makes a signi cant contribution to environmental protection. The application possibi- lities of glass have become very versatile and in certain elds of application recycled glass can be used already up to 90% in the production of new products today. In order to be able to separate laminated glass clean, simple and e cient from each another, a recycling system is required which produces a cleanly separated nal product, but at the same time reduce wear costs and maintenance intervals.

The use of liquids, high speeds of shredders, as well as a cutting shredding in the treatment process, cause an unintentionally increase of wear costs in the glass as well as short replacement intervals of all wear parts. As a result, the cost of recycling PVB laminated glass increases and often makes it seem uneconomical why many laminated glass raw products are still being piled up on dumps around the world.

Our solution - Recyglass®

The idea of the Recyglass® recycling system is the simplest and most cost-e cient separation car windscreen components as well as various other laminated glass and safety glass products. The combination of feed bunker and pre-shredder ensure an easy and continuous product feeding of the complete system. The shredder can be loaded with a wheel loader as well as with a sorting grapple on the excavator with up to 10 tons of material. Thanks to a sophisticated geometry of the shredder shafts, which has been developed steadily over the last years, we achieve both a good throughput, a perfect pre-shredding for sub- sequent work steps, as well as an almost free and low-maintenance pre-shredding. Afterwards, the PTRG 100-67 separates the glass from the PVB foil without further shredding the foil smaller what is important for the separation later on. Subsequently, the foils and glass are separated from one another by a sorting and screening processes. Foil that is not clean enough can be automatically returned to the Recyglass® process for an additional separation to ensure a consistent high-quality end product.

Facts and potentials

Glass is today one of the products that surrounds us every day and everywhere. The application possibilities of glass are cons- tantly evolving and therefore also the amounts of glass waste that has to be recycled. Bottles and at glass have been recycled economically almost everywhere for decades. For some years now, the process of laminated glass processing has been steadily evolving as demand for glass and also for PVB steadily increases. The potential of laminated glass recycling can be recognized from the exponential increase in the global automobile stock. In recent years more and more companies have developed new applications for recycled PVB, which today is mainly made from laminated glass. The Recyglass® system has been specially developed for the separation of glass and PVB foil but also o ers the possibility of recycling bottle glass, solar systems and other glass products with various expansion stages and machine components.
