30 Feasibility and Economics of Biobutanol from Lignocellulosic and Starchy Residues

An extensive research on enhancing the process economy by studying the

operational parameter affecting the ABE fermentation was reported widely.

However, usage of new feedstock and development of stress tolerance microbe alter

the ABE operational condition. Maintaining the fermentation parameter inside the

reactor due to formation of inhibitory compounds is one of the challenges in ABE

fermentation. Research is still needed to explore the development of kinetic model

to study fermentation behavior under transient state for different feedstock and

microbes to increase productivity and to overcome the challenges involved with

reactor design for commercial scale production.

Conclusion

In the twenty-first century mankind is facing the problem of waste disposal and

energy demand due to its growing megacities and industries. The lignocellulose and

starchy residues are one of the waste by-products generated from these industries.

Thus, production of biobutanol from lignocellulose and starchy waste residues is

found to be feasible because of the presence of high carbohydrate content present

in it. Biobutanol is one of the promising advanced renewable fuel which has the

potential to meet the current energy demand. The use of lignocellulose and starchy

waste residues generated from agro-industrial activities to produce biobutanol could

reduce the production cost, making it more economical.
