Advanced biofuels are fuels that
can be processed from numerous types of biomass. First generation biofuels are
processed from the sugars and vegetable oils formed in arable crops, which can
be smoothly extracted applying conventional technology. In comparison, advanced
biofuels are made from lignocellulose biomass or woody crops, agricultural
residues or waste, which makes it tougher to extract the requisite fuel.
Advanced biofuel technologies have been devised because first generation
biofuels manufacture has major limitations. First generation biofuel processes
are convenient but restrained in most cases: there is a limit above which they
cannot yield enough biofuel without forbidding food supplies and biodiversity.
Many first generation biofuels rely on subsidies and are not cost competitive
with prevailing fossil fuels such as oil, and some of them yield only limited
greenhouse gas emissions savings. When considering emissions from production
and transport, life-cycle assessment from first generation biofuels usually
approach those of traditional fossil fuels. Advanced biofuels can aid resolving
these complications and can impart a greater proportion of global fuel supply
affordably, sustainably and with larger environmental interests.
