In Australia, Transgrid has introduced cutting-edge equipment to speed up the recycling of obsolete transmission lines, reducing emissions and saving millions of dollars. The company, operator of high-voltage energy transmission networks in New South Wales and the Australian Capital Territory, has teamed up with the German company Zeck to recycle conductors in western Sydney. The outer layer of aluminium is removed from conductors when fed into the Zeck Al/Steel Separator (ZAS) machine under tension. It is then sliced into 30-70 mm pieces and collected in preparation for smelting into new products. At the other end, the undamaged steel core is coiled onto a cable drum and prepared for recycling.
