The problem that second generation biofuel processes are addressing is to extract useful feedstocks from this woody or fibrous biomass, where the useful sugars are locked in by lignin, hemicellulose and cellulose. All plants contain lignin, hemicellulose and cellulose.
When a feedstock is a renewable biological substance, examples include crops, woody plants, algae, petroleum, and natural gas. Specifically, cârude oil is a feedstock for the production of gasoline.
