Sustainability of energy has always become an issue globally as current energy supplies are depleting gradually. Humans were too dependent on natural gasses as a source of energy before, which brought us to this crisis as they are non-renewable energy and take up to a million years to recover. Not only that, prolonged utilization of this type of energy brought deterioration to our environment. Biofuels are one of the renewable energy sources that are favoured in the industry nowadays. They have the potential to replace non-renewable energy while simultaneously decrease the environmental damage. Sourced from various agricultural residues and other plant substances, lignocellulosic materials are capable of being converted to non-renewable energy due to their lavish availability through three basic steps, pre-treatments, enzymatic hydrolysis and fermentation. This review seeks to observe the prospect of cassava peels as a source for biofuels production and other value-added products such as formic acid, levulinic acid, glycolic acid and vanillin.
