FSP GmbH Opens New Foundry Sand Regeneration Facility in Stuttgart 30. October 2025

In his keynote speech, FSP Managing Director Stefan Zimmermann emphasized the company’s mission: "We are investing in modern technology, sustainable processes, and closed material cycles – creating something new from the old in the true spirit of the circular economy."

Among the distinguished guests were State Secretary Rita Schwarzelühr-Sutter (Federal Ministry for the Environment), Dr. André Baumann (Ministry of the Environment, Baden-Württemberg), Nina Steinemann (Mercedes-Benz AG), and Elke Radtke (German Foundry Association).

Exemplary Support and Technology

The Federal Ministry for the Environment is supporting the project with more than one million euros through its Environmental Innovation Program. The new facility is capable of regenerating up to 16,500 tons of foundry sand annually – while recovering around 70 percent of the energy used in the process.

"This is where we see what happens when entrepreneurial courage, technological innovation, and environmental responsibility come together," said State Secretary Schwarzelühr-Sutter.

State Secretary Dr. André Baumann also praised the project as a “lighthouse for industry,” demonstrating how “resource efficiency, climate protection, and competitiveness can be successfully combined.”

Circular Economy with a Regional Focus Partnership with Mercedes-Benz and Local Value Creation

Alexander Feeß, Managing Director of the Feeß Group and co-founder of FSP GmbH, recalled the origins of the idea in his speech: A meeting with partners from Cologne and Mercedes-Benz four years ago provided the initial spark. “At the beginning, Rhineland optimism met Swabian skepticism – but the idea immediately fascinated us,” Feeß said.

With the founding of FSP in mid-2022, the vision became reality. The patented, energy-saving process makes it possible to reuse up to 95 percent of foundry sand – a vital step for resource conservation and regional value creation. “After only a short time, we were able to deliver the first truckloads of regenerated sand – this time not transported over hundreds of kilometers, but less than ten,” Feeß noted.

He thanked all partners, in particular Mercedes-Benz, public authorities, financiers, and his team: “This is circular economy as it should be – efficient, sustainable, and regional.”

A Step into the Future

With its new facility, FSP GmbH is strengthening Stuttgart as a hub of innovation and demonstrating that industry, environmental responsibility, and economic viability can successfully complement one another.
