Biomass refining is not yet ready to impact in a major way on the gluttonous demand for motor fuel, but a few factories that convert wood to a mix of several products should be highly profitable. There need to be credits from the sale of other chemicals or from excess plant energy in the form of steam or electricity. A biomass refinery will have three major products — fuel alcohol, crude syrup for feeding cattle, and lignin for such applications as adhesive in plywood or chipboard. With good recycle and careful management of plant streams, there will be almost no pollution of the environment. A computer spread sheet for a refining process is used as a teaching tool.
