An artificial firelog is provided comprising combustible cellulosic material, a combustible wax binder and an amount of sodium bicarbonate effective to reduce emissions of particulate matter (PM) and carbon monoxide (CO). The sodium bicarbonate comprises about 1% to about 10% by weight of the artificial firelog. Preferably, the sodium bicarbonate comprises about 2% to about 5% by weight of the artificial firelog. Besides substantially reducing PM and CO emissions during combustion of the artificial firelog, the undesirable odor associated with combustion of the wax binder is decreased and the firelog's total burn time is extended. Moreover, the sodium bicarbonate increases the “poke resistance” of the firelog making the log suitable for outdoor use and a natural appearing white ash develops during the course of combustion.
An artificial firelog comprising from about 40% w/w to about 60% w/w flammable wax binder, from about 60% w/w to about 40% w/w flammable cellulosic material and from about 1% w/w to about 10% w/w of sodium bicarbonate.
An artificial firelog comprising, in combination:
