Roeslein Alternative Energy is using swine manure to produce renewable natural gas (RNG), which can be used to power homes and cars. The company, in partnership with Smithfield Foods, the world's largest pork producer, has nine manure-to-natural-gas facilities in Northern Missouri. The pig manure is deposited in large lagoons covered by impermeable covers. The process of anaerobic digestion produces methane which is captured, refined, and injected into natural gas pipelines.
