For years, Murphy Brown, a subsidiary of Smithfield Foods and the largest producer of hogs in the USA, faced a major issue in its farming operations in Beaver County, Utah. At the time, it had been transferring all the hog manure to settlements tanks where it evaporated, thereby releasing harmful methane gas into the atmosphere in the process. But all that changed in 2012, when the farm’s operators embarked on an initiative that would not only capture those emissions for use as an energy source to power the facility but also reduce the impact on the environment.
