The major issues relating to environmental sustainability such as a heavy dependency on fossil fuels, increased greenhouse gas emissions, pollution, global warming and climate change have prompted many efforts around the globe to seek alternative energy sources that have negligible environmental impacts and societal benefits. There is an immense interest in biofuels research throughout the world owing to its massive potential to address environmental concerns. Biofuels have the capacity to supplement current and future energy demands through being blended with fossil fuels or even replacing them completely as drop-in fuels in automobiles as well as for heating and the power industries. Waste biomass, primarily lignocellulosic biomass (e.g. agricultural crop residues, forestry biomass and energy crops) and microalgae can act as some inexpensive renewable bioresources for the production of biofuels and biochemicals.
