Abstract
Abstract A composite fuel article comprised of particulate consumable material, such as ground corn cobs and husk material; a petroleum derivative, such as paraffin slack wax; a lignosulfonate; and a corn starch. The lignosulfonate is heated and mixed with the corn starch, the wax is heated to melting and then all the constituents are mixed together, compressed under very moderate pressure in a mold, and cooled to form the solid fuel article in the shape of a log or briquette.
