An artificial firelog of the invention includes as constituents (a) a combustible cellulosic material and (b) a combustible non-petroleum wax, wherein the relative proportions of the constituents are, by weight, from about 30% to about 70% of (a) and from about 30% to about 70% of (b) for 100 parts of (a) and (b). In one form of the invention, the combustible non-petroleum wax constituent may include one or more combustible materials derived from plant oils, vegetable oils, animal oils, fats, rosin, pitch, waxy materials and combinations thereof. In another form of the invention, the combustible non-petroleum wax constituent may include a formulated blend of individual non-petroleum wax components. In yet another form of the invention a combustible binding agent can be added to the blend of materials resulting in reduction of the portion of the more costly combustible wax component. A firelog according to the invention can provide a number of benefits, including lower cost, better lighting and flaming performance, and more environmentally sustainable in comparison to firelogs using petroleum waxes.

A binder composition for an artificial firelog comprising a formulated blend, wherein the blend comprises at least one non-petroleum wax material solid at room temperature and at least one non-petroleum wax material flowable at room temperature comprising unsaturated components, wherein the ratio of wax material which is solid at room temperature to wax material which is flowable at room temperature is from about 1.0 to about 2.5.
