Abstract

India is one of the fastest growing economies in the world. India has taken various initiatives to promote environmental sustainability. One of the important initiatives is increasing production and utilization of renewable energy by adopting ethanol biorefineries. Lignocellulosic biomass, which has a complex structure that can be broken down by enzymes to produce products like biodiesel, bioethanol, and various high-value products, is the major feedstock for biorefineries. The chapter presents a review of the various type of catalysts used in biorefineries and their positive impact on the environment.

Lignocellulosic Biomass

Lignocellulosic materials have been the most promising feedstock because of its renewable nature. Lignocellulosic materials includes biomass from agriculture (corn stover, corn cobs, rice straw, sugarcane bagasse), forestry (paper and saw mill discards), naturally occurring terrestrial trees/bushes/grass and energy crops such as elephant grass, Miscanthus which are grown as low-cost and low-maintenance harvest with high yield of lignocellulosic biomass. Energy crops are preferably used for production of second generation biofuels as feedstock.
