Ferrous metals have been recycled for well over a century, as steel does not lose its physical properties during the recycling process. It certainly is economically viable compared to mining iron ore, handling it and preparing it for the smelting process. The energy saving of recycling ferrous scrap is approximately 16% compared to mining and producing steel.
Metfer Trading s.r.o. operates a hydraulic shear for the cutting of ferrous scrap and within the Müller-Guttenbrunn Group a total of 7 shears and 4 shredders are in operation to recycle various input materials. As copper is an impurity for the steel recycling process, the Müller-Guttenbrunn Group has recently added two new shredders specialized to shred electronic wastes with the
objective to reduce the copper content and hence improve the quality of the ferrous scrap that is delivered to steel mills, at the same time improving the quality of the plastic fraction.
Stainless steel is also sourced by Metfer Trading, as it is fully recyclable.
Metfer Trading sources a wide variety of ferrous containing metals. Apart from the ELV (End-of-Life Vehicles) and WEEE (Waste from Electric and Electronic Equipment) the other ferrous fractions can be mixtures of metal wastes from households, building materials, transport equipment, packaging etc. – see also demolition and dismantling services.
Part of the production of the steel scrap is intended for domestic ironworks and steelworks (such as the Hradek Ironworks, Pilsen Steel, ironworks and steelworks in Ostrava, Třinec, small foundries in the country). All scraps are supplied in accordance with CSN or DIN standards.
