Abstract: A method for making artificial fireplace logs includes the initial step of mixing a quantity of grass clippings and leaves with a quantity of wood chips and sawdust to form a mixture. A liquid binder is then added to the mixture until the binder coats the mixture. The coated mixture is then compressed in a mold to form a compacted mass. Once the mass has solidified, it is removed from the mold. Preferably, the proportion of grass clippings and leaves is in a range of 60%-80% by weight of the total weight of all materials of the compacted mass.
