Mest koelen tegen het opwarmen van de aarde: ‘Mest koelen 1.0 + 2.0’ en ‘extern mest koelen’ om de methaanemissie (en ammoniakemissie) in de melkveehouderij te reducerentechnieken

Temperature is a key factor influencing methane emissions from manure. Challenged by the climate crisis, and in the context of the Climate Envelope – Integral Approach program of the Dutch Ministry of Agriculture, Nature and Food Quality, within this research two manure cooling systems were designed, tested and measured in the real-life conditions on Dutch dairy farms. The first one is a system consisting of cooling pipes that float on the manure that is stored in cellars. This system was supported with a previously installed manure cooling system. This combination resulted in an average methane emission reduction (from manure) of 69%. The second system cools manure outside the cellar and returns the cooled manure to the manure cellar. No emission measurements were carried out in this last experiment, but the capacity of the system to cool manure was investigated.
