Biofuels

Different categories of biofuels

• Bioalcohols

  Renewable fuels produced through the fermentation of biomass which offers an environmentally friendly alternative to fossil fuels

  • Ex. ethanol

• Cellulosic Biomass Biofuel (lab)

  Derived from non-food plant materials: agricultural residue or dedicated energy crops. Sustainable energy source with reduced greenhouse gas emissions.

• Biodiesels

  Renewable diesel fuels typically produced from vegetable oils or animal fats through the process known as transesterification. They serve as cleaner-burning alternatives to petroleum diesel.

  • Algae-Based/Microbial Biodiesels

    Renewable fuels derived from photosynthetic microorganisms (algae or bacteria). They offer potential for high yields and reduced land use compared to traditional biofuel feedstock.

• Biogas

  Renewable. Produced through anaerobic digestion of organic matter (agricultural waste or sewage). Made primarily of methane or carbon dioxide. Used for electricity generation, heating, and vehicle fuel.
