Investing in the future: major scheduled maintenance stops at the Aurubis plant in Hamburg

  • Investment of 59 million euros in the current fiscal year alone / total investment around 72 million euros
  • About 500 of our employees and 1500 employees of partner companies work around the clock
  • The legally stipulated maintenance downtime of the primary fuse will be used again for a large-scale upgrade
  • Implementation of more than 480 maintenance and environmental protection procedures

Hamburg, May 04, 2022 – Planned periodic maintenance work has begun at the Aurubis plant in Hamburg. The reason for this is the legal inspection of the waste heat boiler in the primary smelter every three years. For this purpose, the primary smelter was completely closed, processing more than 1.1 million tons of copper concentrate into copper cathodes annually, and the contact plant for the production of sulfuric acid in a controlled manner was closed. In the coming weeks, Aurubis will carry out a total of 480 technical refurbishment and maintenance procedures on major systems in these areas. “In the current fiscal year alone, we are investing €59 million in increasing the efficiency of all connected production facilities and further improving environmental protection on site,” Aurubis Chief Operating Officer (COO) Heiko Arnold explains. The total investment in the closure is approximately 72 million euros.

Large-scale logistical and technical project

“The tempo of regular maintenance downtime is set by law,” says Axel Brand, head of production at Aurubis in Hamburg. “We are also using this time extensively to further improve our processes and systems. We are implementing extensive procedures that we cannot perform during continuous production. Aurubis is again investing heavily in sustainable copper and metal production – and in the future of our location here in Hamburg.”

Aurubis also replaces six heat exchangers in the contact system. This step is already in preparation for the second expansion phase of Industrial Heat Extraction, a project to supply up to 20,000 homes in Hamburg with carbon-free industrial heat. Another milestone in the maintenance stop is the installation of two new, more robust metallurgical cranes, each with a lifting capacity of 125 tons.

Implementation of the maintenance shutdown is a major logistical and technical project, the planning of which began immediately after another major shutdown in 2019. At its peak, up to 2,000 project employees will be working on the plant premises, including 1,500 employees from partner companies, suppliers and service providers. Aurubis has developed its own access management for them and has set up special logistics and infrastructure, including temporary showers, social rooms, parking spaces and a canteen.

Occupational safety takes priority

The protection of occupational safety and health is also a top priority in this major project. All persons working on factory premises undergo a three-stage safety briefing prior to commencing work. In the run-up to the event, “Resource Day in Work Safety” was organized for the first time with representatives of all partner companies. “With a shutdown of this scale and complexity, it is essential that our external partners know well the local conditions and specific features,” says Andreas Heuer, project manager for the 2022 maintenance shutdown at the Aurubis plant in Hamburg. “Thus, consistent implementation of our applicable occupational safety rules is part of our project planning, as is targeted health protection against potential coronavirus infections.”

Planned maintenance shutdowns are being carried out at several major industrial companies, including other Aurubis international production sites. This year’s maintenance shutdown is expected to last through mid-June. In the meantime, Aurubis customers are continuously supplied, since there are enough anodes in stock to be able to fill electrolysis baths and produce high purity copper cathodes. This ensures that the wire rod and continuous cast form production plants also have sufficient input materials to be able to serve all customers.
