2. RWTH Aachen, IME Process Metallurgy and Metal Recycling, Intzestr. 3, 52056 Aachen, Germany Abstract This paper reports the initial results of thermal pre-treatment of used beverage can scrap in an industrial size reverberatory multi-chamber shaft furnace. Apr 27, 2016 electric arc furnace, and lists the CO 2 emissions per ton of steel from both methods. The next section discusses two specific production technologies Midrex and HYL. It relays how they reduce emissions relative to the current standard technology (blast furnace/basic oxygen furnace), and how they differ from one another.
