What are second life biofuels?



  1. 0 Votes

    Second generation biofuels use leaves, stems, husks and other discarded parts of crops not eaten by humans, as well as wood chips, pulp and other waste from industry.  Complex carbohydrates such as cellulose and lignin contain sugars within biomass, and enzymes are used to free the sugars from the cellulose so that they can be fermented into ethanol.
