830 G Material handling machine made from CO₂-reduced “green steel”

Sustainable material handling and high performance are not mutually exclusive – quite the opposite: At DEUMU’s steel scrap recycling facility in Salzgitter, the SENNEBOGEN 830 G impressively demonstrates how CO₂ reduction and efficiency can work together in practice. The 40-tonne material handler, made from CO₂-reduced “green steel,” operates on a roughly 40-hectare, trimodally connected scrap yard. There, it performs a variety of tasks in the recycling process – from unloading ships to loading railcars and trucks. Through the use of CO₂-reduced steel and its low-emission operation, this material handler contributes to a significant reduction in CO₂ emissions.

Decarbonizing the steel industry: DEUMU focuses on sustainable material handling machines

Deutsche Erz- und Metall-Union GmbH (DEUMU) was founded in 1941 and has ensured the supply of raw materials to the steel industry for decades. As a subsidiary of Salzgitter AG, DEUMU is consistently pursuing the goal of decarbonizing the steel industry. A key component of this is the use of modern SENNEBOGEN material handlers, which themselves actively contribute to CO₂ reduction, resource conservation , and the circular economy .

Material handling machine made of green steel: Sustainability throughout the entire product life cycle

The steel for the excavator comes from the Salzgitter Group’s electric arc furnace production line. By using recycled scrap and 100% green electricity, CO2 emissions are reduced by over 70% compared to conventionally produced steel in blast furnaces .

DEUMU supplied steel components for the new SENNEBOGEN 830 G made from precisely this green steel . In its subsequent use, the machine will again be employed in steel scrap handling – thus completing the material cycle.

Uwe Rehren, Managing Director of DEUMU, emphasizes: “We deliberately use CO₂-reduced products at our scrap yard because the Salzgitter Group explicitly wants to play a pioneering role in this area. The new recycling excavator is part of SENNEBOGEN’s latest generation of machines and operates around 20% more efficiently than its predecessor. This results in additional savings of 18.5 tons of CO₂ per year during operation .”

Versatile recycling excavator for trimodal scrap logistics

The 40-tonne SENNEBOGEN 830 G material handler with a 17-meter reach is used flexibly on the DEUMU site wherever high handling capacities are required. Typical areas of application include:

Ship unloading	in the raw material sector (up to 650 tons of scrap metal in 1.5 days, loaded directly into the trucks)
loading	from finished scrap to rail
envelope	from new scrap metal and sheet metal waste
feed	from plants with shredded feedstock (e.g. end-of-life vehicles)

“The SENNEBOGEN 830 is our bread-and-butter machine…”

… It must be versatile – for filling railcars, loading trucks, sorting , and feeding systems. Larger machines would have been too bulky, smaller ones wouldn’t have had enough reach. SENNEBOGEN has consistently delivered high quality here for years and is continuously developing its machines further.”

Integrated contamination measurement system on the gripper

The machine operates 365 days a year in three shifts and covers long distances due to its large surface area. An integrated contamination monitoring system on the gripper ensures safety by detecting and excluding radioactive materials at an early stage .

Machine operator Johannes Hasler praises the new machine control system: “The SENNEBOGEN 830 G is very easy to operate. The intuitive touchscreen and the storable operator profiles make everyday work much easier – especially in the many different areas of application.”

Long-standing partnership with service partner Schlüter

Since 2003, DEUMU has relied on material handlers from SENNEBOGEN and the service provided by their sales and service partner, Schlüter Baumaschinen . The material handler made of CO₂-reduced steel represents a deliberate, strategic, and symbolic step for DEUMU. The goal was to make the circular economy tangible – not just as a concept, but in real-world industrial use. At the same time, the technical feasibility of green steel was to be demonstrated, and a genuine product innovation was to be created.

“SENNEBOGEN is the right partner for this because of the trust and mutually beneficial supplier relationships . This allowed the project to be implemented quickly, transparently, and without lengthy coordination processes. For us, it’s not just the product that counts, but the complete package. If a machine breaks down, we need a solution within a few hours – not after a lengthy administrative process. This has worked exceptionally well with SENNEBOGEN and their service partner Schlüter for years.”

Back to its own origins: The SENNEBOGEN 830 G loads old car bodies into the shredder feedstock – the material from which the steel of the “green steel excavator” is primarily made.
