Video Description: Type of Video: Story*
Description: Imagine if pigs or some wild grass could help you heat your house or fuel your car. St. Louis-based Roeslein Alternative Energy produces renewable natural gas (RNG) from the anaerobic digestion of swine manure, turning pig poop into power. The company is also in the process of creating renewable natural gas from the digestion of native prairie plants. Working in partnership with Smithfield Foods, the world’s largest pork producer, Roeslein takes the manure made by pigs and deposits it into giant lagoons, which are about the size of a small pond. The lagoons are then covered with impermeable covers that keep rainwater out and trap the manure inside.
