Aemetis is an international renewable fuels and renewable natural gas company that develops and operates facilities to produce low and negative carbon intensity fuels from agricultural products and waste. The company operates an ethanol production facility in California, a dairy-waste-powered renewable natural gas system with a network of anaerobic digesters, and a biodiesel facility in India, generating revenue from commodity fuel sales (ethanol, biodiesel, renewable natural gas), co-products (distillers grains, corn oil, glycerin, captured CO₂), and environmental credits (federal renewable fuel identification numbers and California Low Carbon Fuel Standard credits) sold to fuel blenders, transportation customers, feed distributors, and government petroleum companies. The business model depends on market-based commodity prices, regulatory incentives, and long-term customer agreements, while the company pursues expansion of renewable natural gas capacity, development of sustainable aviation fuel and renewable diesel production, and carbon capture and sequestration technologies.
