Cellulosic Ethanol

Cellulosic ethanol differs from bioethanol due to different raw materials, the production process and, in terms of market maturity. Whereas bioethanol, which can be produced from grain or maize, already recorded a significant share in the transport fuel market, cellulosic ethanol is still in its infancy.

As feedstock wood residues, straw and fruit peels are used. The required sugar for fermentation is incorporated as lignocellulosic materials in the cell walls of the plant. These lignocellulose biomass is composed of cellulose, hemicellulose and lignin. For ethanol production cellulose and hemicellulose have to be decomposed by acids and enzymes in their constituent sugars.
