Abstract
In the United States (U.S), biodiesel is produced from vegetable oils, animal fats, recycled restaurant oil, and waste oil. Soybean oil has been by far the most widely used feedstock for U.S biodiesel production, accounting for more than half of the nation's biodiesel feedstock. This study aimed to determine the potential biodiesel volume of the soybean plant, which is the most cultivated product as a first-generation biodiesel feedstock in the U.S. The potential biodiesel volume of the soybean plant, which was grown on an area of 30 352 150 hectares in the U.S in 2019, was calculated as 1 020 749 343 liters. Knowing the potential of oilseed plants used as feedstocks in first-generation biodiesel production will accelerate efforts to identify products that should be used in second-generation biodiesel production and expand their cultivation. Studies should be planned to remove the threat on the food sector by replacing the first-generation biodiesel production feedstocks, which are mainly used as oil feedstocks in the food sector, with the second-generation inedible oil feedstocks that are not used in the food sector.
Highlights
Different biofuel feedstock sources and production processes have many other impacts, including greenhouse gas emissions, life cycle, air pollutants, land and water use
First-generation biofuels are made from sugar crops, starch crops, oilseed crops, and animal fats
This study aimed to determine the potential biodiesel volume of the soybean plant, which is produced in the highest amount as the first-generation feedstock in biodiesel production in the U.S
Summary
Different biofuel feedstock sources and production processes have many other impacts, including greenhouse gas emissions, life cycle, air pollutants, land and water use. Policies on biofuel production and use are directly affected by this situation. Both biofuel technologies and other alternative power train technologies will determine the volume of biofuels and what types of transportation fuels they can integrated them. For the efficient integration of biofuels into the transport fuels market, must coordinate production, transport, distribution, and automobile infrastructure (Mishra and Goswami, 2018; Elgharbawy et al, 2021). First-generation biofuels are made from sugar crops (sugarcane, sugar beet), starch crops (corn, sorghum), oilseed crops (soybean, canola), and animal fats. Third-generation biofuels use algae as a feedstock. Commercial cellulosic biofuel production began in the U.S in 2013, while algae biofuels are not yet produced commercially (Huang et al, 2013)
