"Resource-efficient firelogs made with 100% renewable resources, instead of petroleum, are now available for a 'carbon-neutral' fire. Firelogs produce approximately 70% less toxic air pollution than firewood. They produce significantly less carbon monoxide and creosote as compared to firewood." ~ Oregon DEQ
About Densified Logs
Manufactured, "densified" firelogs made entirely of RECOVERED wood (super-compressed wood shavings and sawdust) adhering through naturally occurring lignin. NO ADDITIVES. See this article on densified wood for more information.
Densified logs burn hotter and cleaner than waxed firelogs (Duraflame, Pine Mountain, etc.) which are unsuitable for woodstoves. Densified firelogs are considered the optimum fuel by most stove makers and sellers because they are made of pure wood dried to an extremely low moisture content (7%).
Densified logs are RELIABLE because of their very low moisture content and because you always know--unlike cordwood--the quantity and quality of product per price.
Densified Energy Logs boast 8,600 BTUs per lb. (hardest cordwoods = 7,000 BTUs per lb.) Sweep's Library
In fireplaces, Energy Logs burn at least two hours, and in most woodstoves up to 8 hours.
