The versatility of scrap and its substitutes

Our portfolio

GMH Recycling processes scrap and non-ferrous waste in such a way that it can be reused in the best way possible. Our entire teams works carefully to make sure this is the case, on the basis of decades of experience and expertise.

Steel scrap

The classification of types of steel scrap is carried out in accordance with the European Steel Scrap Specification. The definitions of individual types of steel refer to non-alloy carbon steel scrap, which can be used directly in steelworks as raw material.

Special scrap

GMH Recycling efficiently recycles special scrap.

During plate iron and steel production, by-products, including iron-containing by-products, ensue. Foundry products accrue as by-products from steel production and are comprised of either plate iron or steel. These materials generally exist in a form which does not comply with customer-specified dimensions and weights and therefore subsequently need to be cut by us to these specifications using our own processing units. Examples of the material forms are:

  • Desulph skulls and steelskulls in various sizes
  • Foundry plate iron from slag processing
  • Castings in the form of dies from the automotive industry
  • Moulds made of cast iron from the steel industry
  • Steel rollers from the paper and steel industry
  • Bulky machines, and heavy and oversized scrap from industrial dismantling

Foundry scrap

We specialise in optimal supply of customised, recycled secondary raw materials to GMH Gruppe's own foundries as well as other foundries. We agree the specific requirement profiles with our customers. You can find our valid list of foundry scrap types in the Download Centre.

Alloyed scrap

In addition to the proportion of iron, alloyed scrap also contains further components such as chromium, nickel or molybdenum.  A distinction is also made in this connection between stainless steels and low-alloy construction steel grades. Examples of stainless grades include the material 4301 (V2A) which contains c. 18% chromium and 8% nickel, and the material 4401 (V4A) which contains an additional 2% molybdenum. Low-alloy steels are distinguishable from stainless grades due to the significantly lower content of chromium, nickel and molybdenum. Examples include the materials 2713 or 2343.

Non-ferrous scrap

GMH Recycling's portfolio includes non-ferrous scrap i.e. all non-iron containing scrap such as copper, aluminium, zinc, lead or tin. It also includes compounds made of several elements such as brass. All types of non-ferrous scrap, to a greater or lesser extent, contain high levels of impurities and contaminations such as plastic or rubber. The classification arises from the usages in the metal trade.

Grinding sludge

During the grinding of metal components, so-called grinding sludge is formed is connection with the cooling lubricants required for the processing. Such sludge comprises significant amounts of metals, ceramic materials, oils and oil-water mixtures - so-called emulsions. This particular grinding sludge is generally hazardous waste. It is processed in the briquetting plant approved for hazardous waste for material recycling in steelworks.

Steel trade

In addition to the supply of scrap and by-products from steel production, GMH Recycling also provides (stainless) steels in a variety of grades and designs. Our product range in the stainless steel trade includes all stainless steel grades in the flat and long steel area. All products can also be supplied in a smooth, brushed or high-gloss polished finish, seamless pipes smoothed or polished on inside (from 6mm inner diameter upwards) incl. TÜV approval.

Precious metals

The precious metals purchased include gold, silver and platinum. These are generally pieces of jewellery in the form of rings and chains as well as cutlery. The precious metal content must be at least 33% for gold, 80% for silver and 99% for platinum.
