The CH4 Livestock Emission (CH4rLiE) project aims at developing a prototype for methane emissions capture in a barn environment. Methane has a higher global warming potential (GWP) with respect to CO2, and methane emissions of human origin contribute about 23% to global warming. Emissions from livestock farms play a non-negligible role, as a single cow is capable of emitting about 110 kg of methane in a year. Several projects have tried to mitigate the problem by intervening on animal feed: CH4rLiE, in contrast, proposes to act on the methane already produced and diffused in the air, using a specially developed recovery system. The idea arose from the expertise acquired in the Large Hadron Collider experiments at CERN, where special gas recuperation systems are being developed to extract CF4 from gaseous detectors' exhausted gas mixture. The project focuses on the study of gas adsorption by porous materials and on the development of a prototype system for methane capture, which will be installed in a real barn. This study is being supported by an initial phase of gas diffusion simulations and by a campaign of measurements of gas concentrations in different barn areas. CH4rLiE will also provide an opportunity to explore, for the first time, the feasibility of methane recovery from the farm environment without affecting the animals' feeding or living conditions. The social benefits are extremely interesting both in terms of developing and implementing low-impact farming production processes, but also in terms of recycling expensive or environmentally unfriendly gasses.
