Advanced (also known as second-generation and third-generation) biofuels must comply with sustainability criteria related to the feedstock used (not competing directly or indirectly with food or feed crops) and to their greenhouse gases emission reduction. These fuels must reach at least 0.2% of transport energy used in Europe in 2022, 1% in 2025, and 3.5% by 2030. In this chapter, sustainable feedstocks that could be used for producing advanced biofuels are reviewed: energy crops grown on marginal land; wastes and residues—agricultural, forestry, food, municipal solid waste, and other organic wastes and residues; and novel feedstocks—such as aquatic biomass (macroalgae and microalgae).
