Firewise: 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 (Source: Dec 2005 Environment Canada/US EPA Reg. 5 Content and emission characteristics of artificial wax firelogs). 75% less carbon monoxide (Source: Dec 2005 Environment Canada/US EPA Reg. 5 Content and emission characteristics of artificial wax firelogs). 90% less hazardous air pollutants (Source: Dec 2005 Environment Canada/US EPA Reg. 5 Content and emission characteristics of artificial wax firelogs). Saves Trees: A duraflame firelog consumes 80% less material than a comparable 4 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. Made in USA.
