Download Development of a novel biofilter cover to offset methane emissions from dairy effluent ponds: Final report

Biofiltration, through which CH4 is oxidised by methanotrophic bacteria, is a potentially effective strategy for mitigating CH4 emissions from anaerobic dairy effluent lagoons/ponds, which typically do not produce enough biogas for energy recovery. This study reports on the effectiveness of a biofilter cover design for oxidising CH4 produced by dairy effluent ponds.
