  • Quick Look at U.S. Monthly Biodiesel Production

    In this short article, we look at pure biodiesel production for 2019. Pure or traditional biodiesel is known as Fatty Acid Methyl Ester (FAME). Renewable diesel (also known as Hydrotreated Vegetable Oil or HVO) and FAME often are confused.

  • Iowa Ethanol Gross Production Margins Update: February 2019

    In this month's report, we look at the ethanol crush spread. Ethanol crush spread is a dollar value calculated as the difference between the combined sales values of ethanol, distillers dried grains with solubles (DDGS) and corn distillers oil (CDO) and the cost of corn in producing ethanol.

  • Update on U.S. Biodiesel Production and Feedstocks Usage in 2018

    In this month's article, we look at pure biodiesel production and its feedstock usage for 2018. A previous update covering pure biodiesel production can be found in the April 2018 Report from the AgMRC Renewable Energy Report.

  • Quick Look at Fuel Ethanol Production and Consumption

    U.S. ethanol production was at 1.028 million barrels per day for the week ending February 22, 2019 according to the most recent Weekly Ethanol Plant Production report from the Energy Information Administration (EIA).

  • Corn Crush for Fuel Ethanol 2016-2018

    In this short report, we look at the amount of corn and sorghum crushed for fuel ethanol production. This data analysis work is based on the Grain Crushing and Co-Products Production report published by the USDA National Agricultural Statistics Service (USDA-NASS).

  • US Fats and Oils: Inedible Grease Market Analysis

    Yellow grease (YG) and choice white grease (CWG) are marginal value commodities. YG can be many products such as used cooking oil, lower quality fat from slaughter houses and rendering plants. CWG is mainly rendered porcine fat. Both YG and CWG are used to produce livestock and poultry feed as a fat source. They are also used in biodiesel production as feedstocks.

  • DIS Works on Animal Feed Trials: Experimental Design Analysis

    Stronger feed trial experimental design and analysis can give the competitive edge necessary to remain ahead, and provide the best inputs to producers and by default the highest quality products to the consumers of animal products.

  • High Oleic Soybean Oil Has Potential to Create Additional Soybean Meal Demand in U.S. Animal Agriculture

    Soybean oil is the most dominant edible oil in the U.S. domestic fats and oils market. Relative abundant supply and cheaper soybean oil are the main reasons behind its dominance in local markets. Approximately 88 percent of total soybean oil production is domestically utilized with the remaining 12 percent exported.

  • Brazil Political Crisis takes Soybean with it

    Brazil's government scandal brought its currency, the Real, down approximately 7 percent within the last 24 hours. This large drop in the Brazil's currency has made U.S. soybean uncompetitive and less attractive in the international soybean market.

  • Pure Biodiesel Production 2009-2016

    Pure or traditional biodiesel is known as Fatty Acid Methyl Ester (FAME) and renewable diesel (also known as Hydrotreated Vegetable Oil or HVO) often are confused. They are both made from organic biomass, but are different products due to their production process and quality attributes.

  • The Value of Engineering and Economics Partnerships on Project Proposals

    How can economic research and engineering work together toward the common goal of informing funding policies and decisions in order to prioritize limited dollars and maximize return on investment?

  • U.S. Ethanol Production Sets New Record

    According to the most recent Weekly Ethanol Plant Production report from the Energy Information Administration (EIA), U.S. ethanol production reached 1.049 million barrels per day for the week ending January 6th 2017. Correspondingly, weekly ending stocks of fuel ethanol are at 20.009 million barrels as published by EIA's Weekly Supply Estimates report.

  • U.S. Ethanol Consumption Sets New Records

    The Weekly Petroleum Status Report released November 9, 2016 by the U.S. Energy Information Administration (EIA) indicates weekly U.S. refiner and blender net input of fuel ethanol was 923,000 barrels per day for the week ending November 4, 2016. The Weekly Supply Estimates from EIA shows the weekly U.S. product supplied of finished motor gasoline was 9,213,000 barrels per day for the same time period.

  • Ethanol RIN prices explode

    Ethanol D6 RIN prices that had been $0.36 per RIN at the end of September 2015 rocketed to $0.97 per RIN by mid-July 2016.Now it has slowly settled into the $0.86–$0.88 range by mid-September 2016.

  • Fuel Economy Standards: Is it over expectation?

    Last June, I happened to read an interesting article “American Drivers Regain Appetite for Gas Guzzlers” from The New York Times. Americans have renewed their interest in bigger cars, pickup trucks, and sport utility vehicles over more fuel efficient small cars mainly due to falling gasoline prices. Later, in July, the Monthly Energy Review from the Energy Information Administration (EIA) reported that the U.S. domestic transportation sector is now the biggest producer of green-house gas (GHG)..
