Abstract
Animal manure is an underutilized biomass resource containing a large amount of organic carbon that is often wasted in the existing manure disposal practices. A research project funded by the US Department of Energy explored the feasibility of using manure via the sugar platform in a biorefinery. The results showed that fiber, the major component of dry manure, constituted approximately 50%, 40%, and 36% of the dry dairy, swine, and poultry manure materials, respectively. The highest fiber contents were in dairy manure of which more than 75% of the dry matter was in the particles greater than 0.125 mm. Manure can be used for substrate to produce cellulase on site. The hemicellulose component in the manure fiber could be readily converted to sugar through acid hydrolysis. Concentrated acid treatment was most effective in manure cellulose decrystallization. The effectiveness of enzymatic hydrolysis was limited without concentrated acid pretreatment. The high protein content in manure had negative affects on acid hydrolysis. Purification and separation is necessary for further chemical conversion of the sugar to value-added chemicals through hydrogenation.
