1. A system comprising:
a closed stable comprising a stable space for housing ruminants;
a methane filter system comprising a methane filter configured for capturing methane (CH4) from stable air fed to the methane filter, to provide (i) filtered air to the stable air and/or to ambient air, and (ii) captured CH4 to a methane consumption system and/or to a methane storage system;
a dinitrogen filter system, wherein the dinitrogen filter system comprises a dinitrogen filter configured for capturing dinitrogen (N2) from the stable air and/or from ambient air fed to the dinitrogen filter, and wherein the dinitrogen filter system is configured to provide the captured dinitrogen (N2) to the ambient air; and
an oxygen filter system configured upstream of the methane filter and configured to lower an oxygen (O2) concentration of the stable air fed to the methane filter to at least below a limiting oxygen concentration for CH4, wherein:
the system is configured for controlling in a controlling mode a methane concentration in the stable air between a minimal methane concentration Cm−≥500 ppmv and a maximal methane concentration Cm+ selected to be equal to or smaller than the lower explosion limit of methane in the stable air CmLEL; and wherein
the system is configured for controlling in the controlling mode a dinitrogen (N2) concentration in the stable air to be smaller than the ambient dinitrogen concentration in ambient air.
