Sustainable steel production with TSR40

The TSR Group demonstrates how the circular economy works in practice today. For this, it received the Circularity Champion Award from the F.A.Z. Institute

Unlike traditional scrap, TSR40 allows larger quantities to be used in steel production – even for demanding applications such as automotive engineering. This has noticeable benefits for the climate, energy consumption and raw material independence. With TSR40, the TSR Group supplies a recycled raw material that meets the quality requirements of modern flat steels – and it is made from everyday waste products: from end-of-life vehicles and household appliances to mixed scrap. These material flows are processed to a high standard in a multi-stage process at our own plants in Duisburg, Amsterdam and Hamburg. The result: a consistently pure material for demanding applications.

Sustainable steel industry: scrap becomes raw material

TSR40 replaces large quantities of primary material in steel production:

iron ore and coking coal in the blast furnace route,
in the direct reduction route DRI/HBI.

This eliminates energy- and resource-intensive steps such as mining, processing and long-distance transport. Because TSR40 meets the high quality requirements of modern flat steels, the recycling content can be significantly increased – up to double in flat steel production.

Recycled raw materials are no longer a niche topic, but a key component of resilient value creation: technically reliable, scalable and immediately usable.

CO₂ savings through TSR40

Another advantage is that TSR40 can be used in blast furnaces, converters and electric arc furnaces without the need for plant conversion. This means CO₂ savings that contribute directly to decarbonisation. In contrast, the transition to hydrogen-based direct reduction often requires considerable investment and technical adjustments.

Circularity Champion Award for resilient circular economy

Technology, quality and impact: The Circularity Champion Award from the F.A.Z. Institute recognises that TSR40 contributes to climate targets and ensures sustainability on an industrial scale.

TSR40 – a joint achievement of industry, research and technology

TSR40 stands not only for high-tech recycling, but also for a new attitude in the industry: circular economy is transformed from an abstract goal into a concrete advantage. For companies, the environment and society. The development of this raw material is not a coincidence, but the result of determined cooperation between industry, research and technology. Behind it all is the will to actively shape change and deliver solutions that can do more than just manage the status quo.

Innovation through collaboration

TSR40 is the result of strong partnerships. From the first prototype to series production, steel manufacturers, technology suppliers and research institutions worked hand in hand. The goal: a raw material that not only meets the requirements of modern, sustainable steel production, but also sets new standards. At the heart of the process is data-based quality management that precisely monitors and controls the processing process – flexibly, transparently and always at the cutting edge of technology.

More security, more independence

TSR40 offers the industry more than just CO₂ savings. Those who rely on recycled raw materials from regional material flows become independent of the vagaries of global raw material markets and gain scope for innovation and investment. The prospective capacity of up to 2.5 million tonnes per year is not just a number – it stands for planning security, competitiveness and tangible prospects for the entire value chain.

Thinking ahead, leading the way, moving forward

TSR40 is the result of close cooperation along the entire value chain. In projects with steel manufacturers and customer industries such as the automotive industry, the recycled raw material was qualified for use in demanding flat steel grades and tested in practice. Partnerships play a key role in this: they combine expertise from recycling, steel production and application and turn a technological innovation into an industrially usable solution – with an impact far beyond the gates of the individual plant.

TSR40 – facts from application

TSR40 is produced from 100 per cent post-consumer materials and made available to the steel industry as a high-quality recycled raw material.
The TSR plant in Duisburg alone processes around 450,000 tonnes of input material into approximately 330,000 tonnes of TSR40 every year; further production lines have been in operation in Amsterdam and Hamburg since 2024, and additional locations are planned
The recycled product can be used in converters, blast furnaces and electric arc furnaces, where it replaces part of the primary raw materials required – with a verifiable reduction in CO₂ emissions in pig iron production
In cooperation with thyssenkrupp Steel, TSR40 forms a central basis for CO₂-reduced flat steel products such as bluemint® recycled
Together with voestalpine and Audi, TSR40 is already being used in series production in the roof section of the Audi Q6 Sportback e-tron, underlining its suitability for demanding automotive applications
