The EMeRGE research project, conducted by the Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB) in collaboration with Alzchem Trostberg GmbH, found that calcium cyanamide can significantly lower methane emissions from manure storage by up to 97%. The study indicates that approximately one-fifth of methane emissions in German livestock farming arise during manure storage.

The additive temporarily inactivates methane-producing microorganisms, maintaining nitrogen efficiency and enhancing biogas yield. The researchers noted similar reductions in emissions during winter, though higher doses may be required.

The use of calcium cyanamide can reduce fertilizer costs by up to 22% in high livestock regions. Future efforts will focus on integrating these findings into climate calculators and potential regulatory frameworks. A symposium on January 21, 2026, will discuss project results and practical implications.
