The objective of this LCA study was to evaluate biofuels produced from sweet sorghum to determine the potential environmental benefits of producing sweet sorghum biofuel compared to conventional fossil fuels. The biofuel production process used for this study differed from other LCAs in that, in parallel to stalk juice extraction and fermentation, residual bagasse and vinasse was pyrolyzed and upgraded to a diesel equivalent as opposed to being fermented or combusted for a source of heat or electricity production.

  • Sweet Sorghum As Feedstock in Great Plains Corn Ethanol Plants: the Role of Biofuel Policy
    Journal of Agricultural and Resource Economics 43(1):34–45 ISSN 1068-5502 Copyright 2018 Western Agricultural Economics Association Sweet Sorghum as Feedstock in Great Plains Corn Ethanol Plants: The Role of Biofuel Policy Richard Perrin, Lilyan Fulginiti, Subir Bairagi, and Ismail Dweikat This research examines whether sweet sorghum, a crop considered more drought-tolerant and suitable for semi-arid areas than corn, could result in an economically viable sweet sorghum ethanol pathway in the Great Plains. We find that that if the D5–D6 RIN price spread exceeds the $0.35/gal recently experienced, the benefits of the pathway would be equivalent to about $90/acre of sweet sorghum, or $0.38/gal of ethanol. Because of sparse cultivation potential, only four the six existing plants in the Nebraska–Colorado High Plains area might expect transportation costs to be low enough for economic feasibility. Key words: RFS2, RIN prices, sweet sorghum syrup Introduction Sweet sorghum is a subspecies of sorghum (Sorghum bicolor (L.) Moench) developed for its high stalk sugar content rather than for grain production. While some ethanol plants in the United States use grain from grain sorghum cultivars as a feedstock, to our knowledge none currently use juice from any sorghum cultivars as a feedstock. Wortmann and Regassa(2011) proposed sweet sorghum as a biofuel feedstock crop for the Great Plains, where the drought-tolerant crop could thrive without irrigation and little—if any—fertilizer. Here we examine the economic feasibility of using fresh sweet sorghum stalks in the Great Plains as a seasonal feedstock substitute for corn grain in corn ethanol plants during a two-month harvest period.

  • Chapter II: Sweet Sorghum Cultivar Options
    View metadata, citation and similarChapter papers at core.ac.uk II: Sweet sorghum cultivar options brought to you by CORE provided by ICRISAT Open Access Repository SS Rao, AV Umakanth, JV Patil, Belum VS Reddy, A Ashok Kumar, Ch Ravinder Reddy and P Srinivasa Rao I. Introduction Sweet sorghum can be grown under dryland conditions with annual rainfall ranging from 550-750 mm. The best areas to produce this crop are Central and South India, subtropical areas of Uttar Pradesh and Uttaranchal. It can be grown on well-drained soils such as silt loam or sandy silt clay loam soils with a depth of 0.75 m. Atmospheric temperatures suitable for sweet sorghum growth vary between 15 and 37°C. Sorghum being a C4 species is adapted to a wide range of environments with latitudes ranging from 40oN to 40oS of the equator. Sorghum in general has relatively a deep root system (>1.5 m), and has the unique feature of being ‘dormant’ under unfavorable conditions and resume growth once environmental conditions are favorable. The productivity of sweet sorghum in postrainy (rabi; October-November planted) season is 30-35% less than that in rainy (kharif) and summer seasons because of short day length and low night temperatures. In order to meet the industry demand for raw materials especially during lean periods of sugar cane crushing, there is a need to develop sweet sorghum cultivars that are photoperiod- and thermo-insensitive with high stalk and sugar yields in different maturity backgrounds. II. Sweet sorghum research and development efforts – past work Initial attempts have been made to develop sweet sorghum by crossing indigenous germplasm with exotic ones that led to the identification of superior ones with high stalk yield and Brix, with moderate grain yield (Rajavanshi and Nimbkar 1996).

Ten dual-purpose hybrids, two sweet genotypes, and two grain landraces of sorghums were characterized under temperate environmental conditions to determine their potential for bioethanol production. Five sorghum hybrids (Ganymed, Hannibal, Tarzan, Merlin, and Zerberus) performed better with respect to cane yield, juice yield, potential sugar, and ethanol yields compared to sweet and grain genotypes. While the sweet genotype KIT1 produced the highest sugar concentration in the stem, the lowest concentration was produced by the grain landrace Razinieh. The study showed that plant height, leaf number, leaf weight, cane yield, and juice yield were positively correlated with the sugar yield in fresh stalk. Sugar accumulation was higher in the central internodes of all genotypes.
