Trimet Showcases at ALUMINIUM 2022 Material Sustainability

Sunday, September 18, 2022

Trimet Aluminium SE/DE is presenting a wide range of services and material innovations for lightweight construction at the leading international trade fair ALUMINIUM 2022 on 27–30 September in Dusseldorf/DE. The materials specialist is gearing its product portfolio to the sustainability requirements of the processing industry and is focusing on minimizing CO2 emissions throughout the product life cycle. With the expansion and increase in personnel at the re-smelting works in its Gelsenkirchen plant, the family-owned company is scaling up its recycling business. Aluminium alloys with a high recycled content are the main focus in materials development. In the area of primary production, the company is working on emission-free furnace technology, enabling primary aluminium to be produced in a climate-neutral manner.  

Trimet is expanding its production plant in Gelsenkirchen, thereby further scaling up its recycling operations. An additional rotary furnace and a casting carousel for aluminium sows will increase production capacity by around 20 %. The expansion is scheduled for completion in 2023, and 15 new jobs will be created. With the expansion, Trimet is continuing to modernize and escalate its recycling operations. In recent years, the family-owned company had already renewed its furnace technology in existing plants, installed a new rotary furnace and completely remodeled the storage areas. This has led to optimizations in immission control and reduced specific gas consumption, while expanding production capacity.

Preparations are also underway to enable the supply of process gas containing hydrogen from a neighboring coking plant. The gas has a hydrogen content of around 60 % and will reduce the CO2 footprint from production by a further 4000 t. Trimet is also installing an ORC system. This converts the waste heat generated during the smelting process into electricity and feeds any surplus waste heat into the public grid. This measure will lead to further significant reductions in CO2 emissions.
