Abstract
Globally, the waste management and green energy has been cited amidst the most unprecedented challenges. Biobutanol, an overlooked renewable energy, could be blended with gasoline for potential biofuel application. The feasibility of producing commercial biobutanol from waste biomass is covered in the present chapter. The potential of butanol industry using Clostrium species was evaluated under varying operating conditions using different waste biomass as substrate was discussed. The effects of various pretreatment and hydrolysis process parameters affecting the biobutanol production were investigated along with the key factors involved. Furthermore, the fermentation process, mode, immobilization of the culture, and integrated biochemical strategies that are currently being practiced for biobutanol production by various researchers were also elaborated. In this line of production, several techniques entailing butanol separation and recovery from the medium were addressed in this chapter. Finally, the involvement of genetic and metabolic engineering for enhancing the biomass titer, process integration, and techno-economic analysis, current challenges and future perspectives for further scaling-up of the process have been discussed.
