As such, there’s an astonishing amount of time and money being funneled into emission control. On-farm biodigesters, for example, take a backend approach by harvesting methane wafting from manure pits. A slew of research aims to curb bovine burps by feeding them seaweed, essential oils, and even a bovine Beano of sorts.
