Significant CO₂ reduction:
biomass steam plant strengthens sustainable energy supply at KOB Wolfstein

At its Wolfstein site, KOB, a subsidiary of HARTMANN, has inaugurated its new energy center featuring a state-of-the-art steam plant. Switching to biomass is the largest single measure to modernize the site’s energy infrastructure and representsa key step in reducing site-related CO emissions. Overall, CO emissions will decrease by 37 percent.
KOB has been producing medical textiles for more than 120 years. With the new steam plant, which went into operation at the end of financial year 2025, steam generation now takes place largely through the thermal utilization of plant-based residual materials from regional agriculture and forestry. Planning, financing, construction and operation are managed by an energy supplier. This transition will reduce CO₂ emissions by around 4,000 tons per year.

Modern technology for sustainable energy generation

The new energy center was completed within the planned 14-month construction period. Groundbreaking took place in November 2024. The facility now provides the plant with heat and steam.

The primary energy sources are residual materials from regional agriculture and forestry, as well as by-products from the wood industry, which are used to generate heat and steam. A gas boiler supplements energy and steam generation during peak demand and in the winter months. The generated steam is used both as process steam in production and to heat the site. For KOB, this marks a major step toward a more sustainable energy supply without compromising reliability of supply.

Dr. Achim Hehl, Managing Director of KOB, emphasizes: “With the new biomass steam plant, we are making a targeted investment in a future-proof energy supply for our Wolfstein site. It is a key element of our sustainability strategy and also strengthens a reliable and long-term energy supply for our operations.”

Long-term investment in the Wolfstein site

The modernization of the energy infrastructure is part of a comprehensive investment program at the Wolfstein site. In addition to the new energy center, the program includes a new wastewater treatment plant and additional major infrastructure measures, such as the extension of the spinning mill production building.

These investments enable KOB and HARTMANN to lay the groundwork for sustainable and competitive production in Germany.
