"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 North Idaho Energy Logs
Manufactured, "densified" North Idaho firelogs are made entirely of RECOVERED wood (wood shavings and sawdust), dried, heated, and compressed at 20,000 psi into logs that adhere through wood's 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 pure wood with an extremely low moisture content (7%).
Densified logs are RELIABLE because they are always "seasoned" and because you always know--unlike cordwood--the quantity of the product.
Densified Energy Logs boast 8,600 BTUs per lb. (hardest cordwoods = 7,000 BTUs per lb.) Sweep's Library
In fireplaces, Energy Logs burn about 2-4 hours, and in most woodstoves 8 or more hours.
