globe Cellulosic Ethanol

Cellulosic Ethanol Feedstocks:

  • Agricultural residues – cereal straws, corn stover, bagasse
  • Forest Residues – wood chips, beetle kill pine, and mill residues
  • Municipal Solid Waste – paper, cardboard, packaging, and urban green waste
  • Energy Crops – switchgrass, hybrid poplar, energy cane, etc.


Wood chipsNEAtech knows cellulosic ethanol. Cellulosic ethanol is produced from lignocellulose, a structural material that comprises much of the mass of plants. Lignocellulose is made up of cellulose, hemicellulose, and lignin. Ethanol made from cellulose is preferred to ethanol made from starch and sugar feedstocks because the raw materials are plentiful, typically of low value and not a source of food. Cellulosic ethanol differs from ethanol made from other sources in the way it is processed.

Benefits of Cellulosic Ethanol:

The future of ethanol is cellulose. In our national mission towards energy independence, reversing the effects of global warming, and strengthening our economy, our strategy must include cellulosic ethanol.

The major benefits gained from producing ethanol from cellulose include:

  • Plentiful feedstock
  • Lower fossil fuel consumption and reduced carbon footprint
  • Reduced green house gas emissions
  • Higher net energy balance
  • Less water, fertilizer, and pesticides required for cellulosic feedstocks
  • Land availability for feedstocks
  • Tax incentives and favorable public policies

The most common issues associated with a Cellulosic Ethanol Project are:

  1. Capital cost
  2. Chemical cost (enzymes)
  3. Product yields

The two primary ways of producing fuel ethanol from cellulosic feedstocks are:

Hydrolysis - the process of breaking down pretreated lignocellulosic materials into smaller units (hydrolysis reaction) followed by fermentation and distillation.

Gasification - the conversion of lignocellulosic materials into
single carbon units and hydrogen. These gases are then “reformed” to fuel ethanol through fermentation or catalysis.
