Researchers from the University of Florida (UF) have found that thousands of gallons of ethanol can be produced from sweet sorghum, according to a study conducted on December 13, 2017.
Sweet sorghum is usually used for breakfast. Recently, researchers have found that 1,000 gallons of ethanol per acre can be produced from three varieties of sorghum, which was developed by UF. Researchers say that ethanol production can be achieved by using sweet sorghum as feedstock. Auto and jet fuel can use this ethanol produced from sorghum.
Since sweet sorghum is available abundantly, researchers see a big potential for fuel production. In the world, this is the fifth largest cereal crop and in the U.S., it is third largest. Sorghum was largely produced by the U.S. in 2014. They require less fertilizers, water is efficiently used and is resistant to drought. These are the reasons for scientists to like sweet sorghum. In this study, scientists are trying to use them as raw material in the production of bioethanol. Eulogio Castro, lead author of the study also worked with the researchers to grow this crop.
After harvesting the crop, it was processed and the sugar-rich juice was collected from the stems. On direct fermentation, this juice can be converted to fuel ethanol. Further, the dry, pulpy residue called the bagasse was processed and ethanol could be again produced from the fermentable sugars generated. It was observed that this juice and sugars derived from bagasse has the potential to produce 1,000 gallons of ethanol per acre.
This natural source by which ethanol can be produced is expected to increase the growth of global ethanol market, as detailed in the global ethanol market report published by Coherent Market Insights.
