The topic in brief
Finding ways to make fuels from renewable sources is among the most active research areas in chemistry.
One strategy is to use biological agents, such as enzymes or whole organisms, to catalyse processes for converting biomass into fuels, or to make fuels by photosynthesis.
Alternatively, the thermochemical approach uses abiological, chemical means to make fuels from biomass.
Each approach offers different advantages and challenges for the large-scale production of biofuels.
