2nd Generation Bioethanol Production Process

This is a "2G (second generation)-bioethanol" process using inedible resources as raw materials. This process does not compete for food resources and leads to reduced CO2 emissions. "2G-sugar" which is an intermediate in this process, can be used as a material for bio-based chemicals.

 2nd Generation Bioethanol Production Process


  • Inedible resources can be used as raw material.
  • Enzymatic hydrolysis can be carried out under the high viscosity condition.
  • Unique hydrolysis process allows for enzyme usage reduction.


  • Raw materials
    • Agricultural or industrial waste (Sugarcane bagasse, Rice straw, Wheat straw, Coffee waste, Palm trunk, Mushroom bed, Waste paper)
    • Wood or pulp
  • Products
    • 2G-Ethanol
    • 2G-Sugar (for bio-based chemicals)

Development Status

  • Demonstrated at 20 m3-scale
  • Viable projects for commercial use for domestic and overseas clients are being investigated
