What makes some wood pellet fuel unique and of top quality is that it is made with clean sawdust and other clean wood waste material primarily generated in the manufacturing of hardwood lumber into various wood products such as kitchen cabinets, hardwood flooring, etc. Only a few manufacturers produce wood pellets from those sources. Other sources of saw dust come from saw mills that produce dimensional lumber for everything from broom handles to wooden shipping pallets. What has evolved over the last 4 to 5 years due to a lack of saw mills making saw dust due to the slow down of our economy is the acquisition of whole fresh cut and dead wood trees. After trees are cut down they are chipped on site and transported to the wood pellet mill where they are processed into saw dust. Some manufacturers transport whole logs to their plant where they are stripped of the bark, chipped, dried and processed into pellets. The advantage of this process is consistency, bringing tighter control of the species of wood being used, the elimination of bark and dirt which sometimes finds its way into the pellets.
Finding new sources of wood close to their facilities is challenging for manufacturers.
