About us

Siegfried Jacob Metallwerke was founded in 1953 in Ennepetal by Siegfried Jacob, who was 21 years old at that time.
Today, the company is the leading, non-corporate, European family-owned company operating in all areas of metal recycling and trading.
The worldwide active Metal Group with its companies all over Europe (100% family-owned), is engaged in trading, processing of non-ferrous metals, residues containing non-ferrous metals and alloyed steels as well as production of Cu-based alloys, Cu-cathodes and high-quality nickel and zinc base materials for the chemical industry.
As an essential part of closed material cycles, SJM in Ennepetal achieves a complete recovery of recyclable materials on an area of more than 300,000m² with approx. 300 employees, state-of-the-art and environmentally friendly recycling facilities and thus makes an important contribution to the security of raw material supply and resource conservation.
On a total area of over 1,000,000m², approx. 1000 employees are employed throughout Europe.

As an important partner of the metal manufacturing and processing industry, we have been developing solutions in the field of metal recycling for more than 70 years and contribute significantly to the optimization of manufacturing and disposal processes of our suppliers and customers. Our scope of services ranges from classic metal trading to the recycling of complex industrial residues in state-of-the-art recycling plants.

Innovative recycling combined with modern environmental protection technology is important to us. Therefore, we are constantly investing in the renewal of our technical facilities for the recycling of complex secondary raw materials. In addition, we invest in the future-oriented development of our specialists and managers. We demonstrate forward thinking in the further development of our processes through digitalization and automation.

We stand for the safe and environmentally compatible recycling of non-ferrous metals from industry and commerce. By professionally processing these metals, we produce valuable recycled raw materials, which we then feed back into the economic cycle.

As a European employer, social responsibility – in matters large and small – is an integral part of our corporate culture. We understand the immense social importance of recycling, so the Jacob Metal Group operates responsibly with all the required certificates and permits in compliance with the applicable laws and regulations. We invest in all areas of the company, from quality improvement and occupational safety to new environmentally friendly technologies. Thanks to our decades of experience, and the fact that we are consistently using and developing the latest processing technologies, we are already contributing to conserving resources and protecting the climate today – and we will continue to do so in the future.

Sustainable management and a clear commitment to the Ennepetal site are important hallmarks of our actions. We have felt closely connected to the region and its residents for more than 70 years now and support a wide range of cultural, social and sports projects. In this respect, we consciously accept our responsibility for people and employees and have been a long-standing sponsor and partner of many local clubs and associations. Our employees, most of whom also come from our region, are committed to the company through their loyalty and high motivation. The extremely low fluctuation and the exceptional loyalty of our colleagues are also a clear expression of this bond.
