Decarbonising the Lime Industry!

Together with our partner Calcis Warstein GmbH & Co. KG and other leading companies from the German lime and dolomite industry, we officially commissioned our BORSIG CO₂ capture demonstration plant in Warstein on 16 April 2026.

Why is this so important?

Lime production involves a chemical process where CO₂ is released as an inherent part of the reaction. This process-related emission cannot be avoided technologically—but it can be captured!

While traditional methods often require large quantities of critical additives and significant thermal energy, BORSIG relies on our highly efficient membrane technology.

Key Facts about the Pilot Project:

• Energy Efficient: BMT polymer membrane technology enables energy-efficient, continuous CO₂ capture directly within the process stream—without the need for chemical additives.
• Field Test: A one-year continuous operation to validate gas throughput capacities and membrane service life.
• A Collaborative Effort: A joint project between BORSIG and Calcis, the maxit group, Kalkwerke Otto Breckweg, Hans G. Hauri KG Mineralstoffwerke, Kalkwerke H. Oetelshofen, Köhler Kalk, Märker Gruppe, SCHAEFER KALK, Germann Trollius GmbH, Wünschendorfer Dolomitwerk, Zement- und Kalkwerke Otterbein, and the Research Association of the Lime Industry (FGK).
• Scalability: Following a successful trial, the full-scale deployment of BORSIG technology is planned.

Technology Meets Responsibility

We provide the technological solutions to enable the industry to achieve climate neutrality by 2045—and potentially even become climate-positive through the natural CO₂ binding properties of lime.

A sincere thank you to all our project partners for their trust in BORSIG's technical expertise. Together, we are clearing the path for a green industrial future.
