Aurubis plans to complete an automated preprocessing facility for metal-bearing intermediates at its Hamburg site in 2028. The company confirmed the expansion this week, adding another construction project to a multi-plant footprint that already ranks among the largest copper smelting and recycling complexes in Europe.

The new building will handle metal-bearing intermediates before they enter the smelting route. Automation sits at the center of the design: the company states the facility will preprocess these materials automatically, a step that today involves a higher share of manual handling at existing installations.

Hamburg remains the anchor of the group's German operations. The port city location gives the site direct access to seaborne shipments of recycling materials and concentrates, and the preprocessing step prepares those inputs for the smelters that follow.

What does the investment change?

For Aurubis, the project extends capacity at the front end of its metallurgical chain. The company describes the facility as a further expansion in Hamburg, which positions the site to take in more metal-bearing intermediates as they arrive and to prepare them for processing with less manual intervention.

For suppliers of complex recycling materials, the message is equally direct. Aurubis has built its business on treating input streams that carry a mix of metals, and a dedicated automated preprocessing line signals continued demand for those materials at the Hamburg works beyond the current decade's midpoint.

The 2028 completion date gives the market a fixed milestone. Construction projects of this type at operating smelter sites typically run through permitting, procurement and tie-in phases before startup, and the company has now placed a public date on the finish line.

The deadline to track

Aurubis has committed to a 2028 completion for the automated preprocessing facility in Hamburg. That date now serves as the reference point for the expansion: when the plant starts up, it will show how much additional preprocessing capacity the group has added, and how the automated design changes throughput of metal-bearing intermediates at the site.

Until then, the Hamburg complex continues to operate its existing processing lines. The new facility joins the site's expansion queue with a completion date four years out, and the industry will watch whether Aurubis holds that schedule.
