Eminex^® by Alzchem significantly reduces methane emissions in dairy barns

Methane emissions from dairy cattle farming are increasingly becoming the focus of research and climate protection efforts. In addition to enteric fermentation, the storage of liquid manure also plays an important role. Results from a field trial confirm that the use of Eminex^® leads to a significant reduction in methane emissions in dairy farming.   

Gas concentration measurements were carried out over a period of more than one and a half years in the experimental barn of the Haus Riswick Teaching and Research Institute of the North Rhine-Westphalia Chamber of Agriculture. The investigations focused on the gases methane, carbon dioxide and ammonia. The data were collected as part of two research projects funded by the Federal Ministry of Agriculture, Food and Rural Affairs.  The emission measurements were carried out in four compartments with slatted floors and liquid manure storage under practical conditions.   

As a result of pronounced foam formation during a winter storage period, the slurry treatment aid Eminex,^® a product of Alzchem Group, was used. Shortly after dosing, there was a significant reduction in foam formation and a more homogeneous consistency of the stored liquid manure. Repeated stirring of the slurry was therefore no longer necessary.  

The comparison with the control period showed a reduction in methane emissions of 40.5 kg methane per animal per year. Using IPCC data, a 92% reduction in methane emissions from manure can be estimated. This corresponds to a significant reduction of around 17% at barn level. Considering the global warming potential of methane, this results in a saving of around 1.1 tonnes of CO₂ equivalents per animal per year. 

The results confirm that Eminex^® also makes a significant contribution to reducing GHG emissions on a practical scale. At the same time, there are practical advantages, such as reduced foaming and more efficient use of existing storage capacities.
