Use of reverse osmosis concentrate for mitigating greenhouse gas emissions from pig slurry.

ABSTRACT: Due to the high global warming potential (GWP) in a short time scale (GWP100 = 28 vs. GWP20 = 86), mitigating CH₄ emissions could have an early impact on reducing current global warming effects. The manure storage tank emits a significant amount of CH₄, which can diminish the environmental benefit resulting from the anaerobic digestion of manure that can generate renewable energy. In the present study, we added the reverse osmosis concentrate (ROC) rich in salt to the pig slurry (PS) storage tank to reduce CH₄ emissions. Simultaneously, pure NaCl was tested at the same concentration to compare and verify the performance of ROC addition. During 40 days of storage, 1.83 kg CH₄/ton PS was emitted, which was reduced by 7-75% by the addition of ROC at
