Manufactured Logs

Manufactured logs, typically made of compressed sawdust or other organic matter, provide a cleaner alternative to wood for open-hearth fires.


  • Cleaner than wood. Manufactured logs produce up to 70% less air pollution than wood and less creosote buildup in your fireplace. The Agency has conducted emission testing of manufactured logs. Find more information about this study (PDF).
  • Efficient. One log burns for 2 to 4 hours, depending on the type you select.


  • Not all varieties are suitable for wood stoves and fireplace inserts - check the guidelines on the wrapper to ensure compatibility with your device.
  • Cannot be used during burn bans.
