Assessing the feasibility of biofiltration for methane reduction on Pennsylvania dairy farms

Biofilters, columns of support media colonized by methane oxidizing microbial communities, can be used to mitigate low-concentration methane. While pilot-scale biofilters show potential, little is known about their effectiveness when scaled for industrial use. Not enough research has been conducted on their environmental feasibility when scaled up to effectively put biofiltration to widespread use. We discovered that methane biofiltration may reduce total dairy farm emissions by 37% if applied to treat enteric and manure-related emissions.
