(Lux Research/Ethanol Producer Magazine) Lower feedstock prices can drive down prices of fermentable cellulosic sugar to 26 cents per kilogram (kg), down from 32 to 36 cents per kg, competitive with sugars from corn or sugarcane, according to Lux Research. This advance would allow bio-based chemicals and biofuels to be made from more plentiful non-food sources, helping them better compete with petroleum-based chemicals and fuels.
“Feedstock is the single largest driver of overall fuel production economics. While agricultural waste is a common target feedstock, municipal and industrial waste can be near zero cost, or even negative cost,” said Andrew Soare, Lux Research senior analyst and the lead author of the report titled, “Cellulosic Chemicals and Fuels Race to Compete with First-Gen Sugar Economics.” “While enzymes are a big cost driver for cellulosic sugar, methods such as supercritical fluid processes that don’t use enzymes at all can offer cheaper options,” he added.
