Methane is the second-most common greenhouse gas emitted in the United States and is a major contributor to global warming, says Mango Materials founder Molly Morse. She explains to the SB’13 audience how her company uses simple biological processes in which bacteria “eat” methane, which results in a type of bioplastic as a byproduct. “Mango Materials have the potential to change the plastics industry and the world,” said Morse.
