amount of biodiesel per acre of soy
“The amount of N it takes to raise an 80-bushel soybean crop is tremendous,” Bohner said. In Europe, rapeseed oil is the major biodiesel feedstock. In the United States, soybeans are the dominant biodiesel feedstock. If biodiesel … Even soybean production only yields about 60 gallons of oil per acre [7]. Higher yield ratios indicate that corn is relatively more productive than soybeans, and vice versa. Algae could potentially produce 10 to 100 times more fuel per acre than other crops. Soybeans produce approximately 1.5 gallons of oil per bushel. Algae yield is not included in the yield tables because, in spite of all the hype about yields of 20,000 gallons of oil per acre and even 100,000 gallons per acre and so on, biodiesel from algae is still something of the future, not of the present. This translates to an oil yield of 66 gallons per acre. Environmental Benefits of Biodiesel If the entire arable land area of the USA (470 million acres, or 1.9 million square kilometers) were devoted to biodiesel production from soy, this would just about provide the 160 million tonnes required (assuming an optimistic 98 US gal/acre of biodiesel). Holding all other variables constant, the FER of soybean biodiesel is estimated to reach 4.69 in the year 2015 when soybean yield is projected to increase to 45.3 bushels per acre. This increase of corn for ethanol production decreases the amount of food available for the growing population. Biodiesel Education Program at the University of Idaho. Soybeans. Today most U.S. biodiesel is produced from soybean. But despite its value as a protein source, soybean only provides the equivalent of about one barrel of oil per acre. But Mr. Basse said ethanol production is far more efficient, with some 420 gallons of ethanol produced per acre of corn versus only 60 gallons of biodiesel per acre of soybeans. 6; Biodiesel from algae is an area of ongoing research. where: V is the volume of bio-diesel produced on an amount of farmland; a is the acres in soybeans; gpa is the bio-diesel production rate for soybean volume per acre (default of 66 gallons / acre) Production came from 85 biodiesel plants with capacity of 2.5 billion gallons per year. One bushel of soybeans also yields about 44 pounds of soybean meal, a valuable co-product used as a protein source in animal feed rations. If you are looking for any biodiesel related information, this website provides you with an unbiased information through peer-reviewed publications, videos, technical notes, and thousands to literature organized with the topics you are looking for. The formula for the volume of bio-diesel fuel from an amount of acreage is : V = a • gpa . A team led by the University of Illinois has engineered sugarcane plants to produce 12 percent oil by weight, and expect to reach 20 percent in the future. In the U.S., soybean oil, corn oil, and recycled cooking oils are common feedstocks. The Illinois Central CRD has a 210.4 bushel per acre average corn yield, a 64.0 bushel per acre soybean yield, and a 3.29 corn-to-soybean yield ratio (3.29 = 210.4 corn yield / 64.0 soybean yield). Sales - Producer sales of biodiesel during December 2020 included 74 million gallons sold as pure B100 (100% biodiesel) and an additional 73 million gallons sold as biodiesel blends (contains both pure biodiesel and petroleum diesel fuel). A typical soybean yield of 50 bushels per acre results in the production of about 60 - 75 gallons of B100 and about 1.1 tons of soybean meal per acre. Despite this increase in ethanol production, corn only produces about 328 gallons of corn biofuel per acre [6]. U.S. farmers produced a record-breaking yield in 2009 of 44 bushels per acre. Biodiesel can be made from animal fats, grease, vegetable oils, and algae. “When measuring the total N in the seed and stover for an 80-bushel soybean crop, it takes 387 pounds, compared to 270 pounds of N in a 200-bushel corn crop.” As of end-2011, there is no such thing as biodiesel from algae apart from a few laboratory samples.
