to remove a majority of sugars therefrom the remaining ligno cellulosic residue commonly known as bagasse is converted into combustible pellets or alternatively stored for future pelletization storage is accomplished by first piling the bagasse on a hard surface the bagasse is then compressed to form a compacted mass compression frees trapped air in the pile hindering oxidative degradation by bacteria and other microorganisms application_number US 68585184 A description the present invention involves the production of combustible energy materials from sweet sorghum it should be noted that the concepts and processes described herein are not necessarily limited to sorghum for example sugarcane varieties having the desired characteristics may be used in the invention however sorghum is preferred over sugarcane for a variety of reasons sorghum has a shorter growing season and shows superior drought resistance according to monk et al in 34 improvements of sorghum for energy production 34 supra a frost free period of 100 140 days will mature adapted sorghum cultivars these characteristics allow sorghum to be grown throughout the continental united states conversely sugarcane is a tropical grass which requires warm humid conditions it can only be grown in certain areas for these reasons sorghum is preferred over sugarcane and the invention will be described below using sweet sorghum it is important to choose the right variety of sorghum in order to obtain a fuel product which burns cleanly and efficiently we have discovered that the variety should have at least 5 by weight extractable sugar less than 0 75 dry weight total nitrogen and should yield at least five tons dry weight of biomass per.
