Ethanol(C2H5OH), also known as ethyl alcohol or grain alcohol, is a high-octane liquid fuel derived from various plant materials, or “biomass.” It is a renewable, non-toxic, clean burning fuel alternative to traditional fuels that can reduce greenhouse gas emissions by as much as 50%.
Ethanol is produced by fermenting and distilling plant starches, sugars or cellulosic material:
- starch: corn, barley, and wheat.
- sugar: sugarcane (primary feedstock in Brazil)
- cellulosic: wood, corn stalks, rice straw, sugar cane bagasse, pulpwood, switchgrass, algae, and municipal solid waste.
