  • Patent number: 6136054
    Abstract: A low cost and an environmentally-friendly synthetic firelog is made by mixing specially processed waxed-cardboard or other wax coated papers of varying proportions with a binder/fuel. The binder/fuel consists of a petroleum wax or a mixture of waxes, the nature and extent of which is suitably modified by in situ admixture with the paraffin wax already present in the waxed-cardboard. Sawdust or other wood fillers may also be added. Upon thorough incorporation of the materials, the resulting mixture is extruded, molded, compressed, or otherwise formed, such that the resulting mass is sufficiently solid to hold its shape at normal room temperature.
