About Bioethanol: 

  • It is categorised as first (1G), second (2G) and third-generation (3G), based on the source of raw material used for bioethanol production 
  • First generation (1G) bioethanol uses corn seeds and sugarcane as raw material 
  • Second generation (2G) bioethanol uses inedible farm waste left over after harvest. Corn cobs, rice husks, wheat straw and sugarcane bagasse can all be transformed into cellulose and fermented into ethanol 
  • Third generation (3G) bioethanol uses algae grown in wastewater, sewage or salt water to produce bioethanol
