Stability and Use of Sweet Sorghum Bagasse

With sweet sorghum production and subsequent accumulation of bagasse on the rise, it is important to look for novel uses for its by-products. Bagasse, the solid fibrous product left after sweet sorghum stalks are crushed to remove juice, is partially reapplied to the field to enhance subsequent crops. The majority of bagasse remains largely underutilized because more is produced than can be practically applied to fields. This study determined sweet sorghum bagasse chemical and microbiological properties for use as a fuel source. It was determined that sweet sorghum variety had no major effect on fuel value. Microbes have the potential to consume sugars and other beneficial compounds in bagasse, but our analysis of microbial counts showed that microorganisms did not reduce the fuel value of the bagasse tested. Sweet sorghum bagasse was also found to have favorable fuel value when compared to sugarcane bagasse, due to its lower ash and higher fixed carbon contents.
