Save Trees: Duraflame firelogs use only recycled wood and agricultural fibers, saving valuable natural resources. A Duraflame firelog consumes 80% less material than a comparable 3 hour wood fire, and burning firelogs instead of wood results in significantly fewer trees cut down for use as firewood. Made from 100% Renewable Resources: Duraflame firelogs are made from 100% renewable waxes and oils combined with recycled wood and agricultural fibers. No petro-chemicals are used. Burns Cleaner than Wood: Duraflame 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. 80% less fine particles. 75% less carbon monoxide. 90% less hazardous air pollutants.
