Low Carbon, Low Cost and Made in America

With more than 15 billion gallons of annual domestic production, ethanol has emerged as a critical tool to combat climate change. Not only is ethanol 46% (2021 GREET) lower in greenhouse gas emissions than the petroleum alternative but this energy is manufactured and grown in America, resulting in energy independence. Alongside ethanol, biofuel manufactories isolate the important components of the corn kernel with nutritional value (protein, fat and fiber) and concentrate those components into a protein-dense food that is both cheaper to buy and less carbon-intensive to transport.

Why Choose Biofuel

    Saving Consumers

    A 2022 study by ABF Economics found that E15 saved US consumers an average of 16 cents/gallon. If E15 was available across the country, it would save consumers $20.6 billion in fuel costs.

    Saving the Planet

    On average, ethanol reduces greenhouse gas emissions by 46% when compared to petroleum. Marquis is on track to double the reduction in greenhouse gas emissions from our ethanol by 2025, resulting in a fuel energy product that is 90% lower in greenhouse gas emissions than petroleum.

    Supporting Rural Economies

    Marquis purchases half of the grain grown within a 65-mile radius of our facility. The ethanol industry provides more than 188,000 jobs—a majority in rural environments—while giving local farmers a reliable place to bring their grain while increasing demand for their product.

    The Fermentation Process

    Marquis Energy ethanol is produced through the natural process of fermentation, enhanced by cutting-edge enzymatic and technological developments, to efficiently convert the starch in corn to fermentable sugar. Because we are committed to utilizing every part of each kernel of corn, we also produce Distillers Dried Grains With Solubles (DDGS), Distillers Corn Oil (DCO), and Pure Biogenic Carbon Dioxide.

Fermentation Co-Products

We are committed to utilizing every part of each corn kernel; we innovate what others view as waste to provide low-carbon solutions.  Marquis, a bio-ethanol facility, uses the natural process of photosynthesis and fermentation to create ethanol and three co-products: Distillers Dried Grain with Solubles (DDGS), Distillers Corn Oil, and Pure Biogenic Carbon Dioxide.

    Distillers Dried Grain with Solubles (DDGS)

    Bioethanol also plays a vital role in low-carbon feed solutions.  Fermentation converts starch and sugars to ethanol, but the remaining fat and protein are concentrated into an animal feed product called Distillers Dried Grain with Solubles (DDGS). Distillers Dried Grain with Solubles offers a long shelf life with good energy and protein supplement in feed for cattle, poultry, and swine.  Additionally, Marquis produces a high-protein meal known as ProCap Gold which is an even further-concentrated source of protein for animals and aquaculture.

  • Corn Oil Extraction Technology Marquis ProCap 4

    Carbon Neutral Distillers Corn Oil

    Marquis Corn Oil is leading the path to offering sustainable energy solutions to the hard-to-decarbonize heavy transportation sector. Through the Marquis ProCap technology, we are able to capture corn oil at its highest value. The Marquis Distillers Corn Oil plays an essential role in offering a low-carbon intensity (CI) score feedstock for renewable diesel and biodiesel production. Not suitable for the food industry, this solution tackles greenhouse gas (GHG) emissions to create a more sustainable world.

    Pure Biogenic Carbon Dioxide

    At Marquis, 1.2 million tons of pure, biogenic carbon dioxide is captured during fermentation each year. This extremely pure CO2 captured through the fermentation process enables Marquis to lead the world in providing low and even negative carbon-intensity feed an fuel solutions.

A Look Ahead: Ethanol as a Platform Molecule

Ethanol can be converted into the molecule ethylene, which is a ubiquitous building block for many other products. In the future, ethanol and ethylene can be used to create products such as Sustainable Aviation Fuel (SAF), renewable diesel, bioplastics and a number of other products.
