Saves Trees: A duraflame firelog consumes 80% less material than a comparable 2.5 hour wood fire, and burning firelogs instead of wood results in significantly fewer trees cut down for use as firewood. Recycled & Renewable: 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.
