Green Plains Inc. operates as a major producer of fuel-grade ethanol and value-added agricultural ingredients. The company's business is structured around two primary segments: Ethanol Production and Agribusiness and Energy Services. Through its network of biorefineries across the U.S. Midwest, Green Plains converts corn into low-carbon ethanol, renewable corn oil, and distillers grains. The agribusiness division supports these operations by handling grain procurement, storage, and the marketing of both company-produced and third-party commodities. In recent years, the company has strategically shifted toward producing higher-margin products, such as ultra-high protein feed for aquaculture and livestock. Additionally, Green Plains is implementing carbon capture and sequestration technologies across its facilities to reduce the carbon intensity of its fuels.
