CH4 Biogas: A Leader in Renewable Energy Solutions


To Lauren Toretta (MBA 2007), waste is one of the United States' largest untapped energy resources. Partner and President of CH4 Biogas, Toretta and her team are harnessing organic waste to produce biogas. The company's facilities each handle about 400 tons per day of organic food-grade waste and manure, keeping thousands of car equivalents of carbon out of the atmosphere and producing green, baseload energy that can be used in a variety of applications. CH4 Biogas has worked to create and stabilize the nascent biogas industry through focused policy work and the building of biogas plants. Follow the company on Twitter @ch4biogas and their website.
