A Duraflame firelog consumes 80% less material than a comparable duration wood fire, and burning firelogs instead of wood results in significantly fewer trees cut down for use as firewood. These firelogs light faster and burn more completely than firewood, and because far less material is consumed when burning a firelog, significantly fewer pollutants are emitted than a comparable wood fire. Duraflame firelogs use recycled and renewable wood sawdust and agricultural fibers, saving valuable natural resources. The renewable fibers are mixed with blends of wax and other combustible, renewable materials.
