Our Project:
Capturing CO₂ with catch4climate
On the grounds of the cement plant in Mergelstetten, we are building our own research and development facility that uses the so-called oxyfuel process for CO₂ capture, employing pure oxygen.
Through the “catch4climate” pilot project, we are actively tackling CO₂ capture.
The capture of CO₂ enables its subsequent utilisation or storage (CCU, CCS). Carbon is urgently needed in many industries.
Climate Protection Through New Technologies
The Pure-Oxyfuel process (derived from 'oxy' for oxygen and 'fuel' for fuel) is a clinker firing process in which pure oxygen is introduced into the kiln instead of air. This ensures heat generation while excluding atmospheric nitrogen during combustion. In this way, the CO₂ concentration in the exhaust gas within the kiln is increased to approximately 90 percent, significantly enhancing the potential for CO₂ capture. The objective is to cost-effectively capture 100 percent of a cement plant's CO₂ emissions. By utilizing this technology, the European cement industry could achieve a significant reduction in process-related CO₂ emissions, thereby making a vital contribution to climate protection.
