We are a privately owned company with approximately 300 employees. On an area of 300,000 m² we use our modern recycling facilities to contribute to the protection of raw materials and to conserve resources.

What’s our job?

We are a major partner of the metal manufacturing and processing industries. For more than 60 years now, we are developing solutions in metal recycling and make an important contribution to the optimization of production and disposal processes of our suppliers and customers. Our services range from classic metal trading to recycling complex industrial residues in modern recycling- facilities.

Several laboratories, advanced analytical technology and highly skilled workers ensure an accurate quality identification of metals and metallic residues, thus forming the basis for an efficient, high quality recycling.

What are our plans?

Innovative recycling in combination with modern environmental protection technology is important to us. Therefore, we constantly invest in the renewal of our technical facilities for the recycling of complex secondary raw materials.


Sustainable economic activities, protection of resources by recycling and maximized utilization of raw materials by conversion into products are the main priorities of SJM. [more]
