History of Siegfried Jacob Metallwerke

Sustainable management, resource conservation through recycling and the fullest possible utilization of raw materials by conversion into products are our top priorities.

Metal Recycling is our DNA

We make recycling possible. Always and everywhere.

OUR MISSION: For us, there‘s no waste, just raw material.

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

OUR VISION: Resources are limited. Our ideas are not.

By consistently broadening our ability to recycle, we are advancing sustainability to counter the global extraction of limited natural resources. All our concepts are based on the almost unlimited recyclability of non-ferrous metals, thereby enabling us to ensure the availability of valuable raw materials for future generations.

OUR RESPONSIBILITY: Long-term sustainability for people and the environment.

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.

Our Strategy

Long-term goals need a strategy. With it, we at Jacob Metal Group want to show our employees, our partners and our customers the perspectives that we see for ourselves in the future.
