Metal recycling is sustainability at its purest

Our task carries great responsibility, and it’s one that we fulfil with the utmost commitment and passion. Our team is highly qualified and highly motivated. They work with state-of-the-art plant, handling and analysis technologies and share our objective of almost 100% recycling. At Siegfried Jacob Hamburg, cutting-edge technologies and environmentally responsible processing and storage of metal and alloy scrap go hand in hand. Whether it’s brass, copper, aluminium or zinc, we close the loop – globally.

Sorting and separating

SJH’s high-quality recycled raw materials start with the sorting team, who have decades of experience and a passion for non-ferrous metals. Only by manually presorting each item that we receive we can ensure a consistently high standard of quality.

Cutting, tearing and crushing are essential processes in the production of high-quality, recycled, unmixed raw materials from composites.

cutting // shredding // granulating // briquetting


SJH makes the difference. With our state-of-the-art technologies, we can automatically separate even the smallest grain sizes based on their physical properties, thereby allowing us to recover raw materials in their purest form.

We close the loop – ongoing quality controls of incoming goods and after reprocessing our recycled raw materials ensure a consistently high standard of quality. State-of-the-art technologies and our skilled team with many decades of experience are what make the difference.
