Around 70 – 80 % of used tires worldwide are nowadays reconditioned and largely recycled. Used car tires often come from garages, car dealerships or collection points and must be disposed of in an environmentally friendly manner. They usually consist of synthetic rubber, textile cord inserts, steel wires and other materials, which are sorted and processed in specialised recycling plants.ARJES two-shaft shredders are used to pre-shred car, truck, earthmoving and agricultural tires (EM and AS tyires) and other rubber waste in order to separate the various components. Magnetic separators sort out ferrous foreign matter such as steel wires, which is essential for subsequent processing.
