Advanced biofuels are fuels manufactured from various type of biomass, which includes waste from agricultural, urban, and other wastes. It also known as second-generation biofuels. These biofuels are made from woody crops or lignocellulosic biomass, sugars, non-starch, and agricultural residues, which makes it harder to extract the required fuel. The second-generation biofuel is developed to overcome the limitations of high freezing temperatures and negative environmental effect of first-generation fuels (such as vegetable oil, biodiesel, bioalcohols, biogas, and syngas) and they can supply large amount of global fuel sustainably, which is affordable with higher environmental benefits.
