2<sup>nd</sup> Generation Ethanol Technology

Praj Matrix has developed a proprietary technology for 2nd generation ethanol based on research and development over a decade.

Trials have been taken on various agricultural residues including rice straw, sugarcane bagasse, corn cob, corn stover, cane trash, palm empty fruit bunch, wood chips, wheat and rice straw, and grasses etc.

Production of ethanol from lignocellulosic biomass comprises 3 steps –

  • Pre-treatment(Alteration of structural and chemical composition of biomass to facilitate hydrolysis)
  • Hydrolysis(Conversion of polysaccharides to monomeric fermentable sugars)
  • Fermentation(Fermentation of sugars into ethanol by microbes)

Technology strengths

  • Optimized pre-treatment
  • Fractionated streams
  • Energy integration
  • Optimized design, engineering and fabrication
  • Effluent management
  • Co-fermentation of hexose and pentose sugars
  • Enzymatic hydrolysis
  • Technology audited by internal and government agencies
