Abstract

A synthetic firelog is made by binding cellulosic particles with a combustible binder produced by the interaction of a liquid combustible by-product or waste product and a modifier, the resulting material being such as to be carbonizable on combustion to form a porous skeleton which maintains the shape of the log during burning. The by-product may be molasses, various waste oils or pitches, or sulphite lye and the modifier interacts physically or chemically therewith to form a plastic, thixotropic binder material. The cellulosic material may be sawdust, paper, or any of a variety of cellulosic residues from the processing of vegetable materials.
