Sawdust pellets are an alternate fuel, made from compressed sawdust, or from other lumber byproducts, or related byproducts, like cherry pits. Sawdust was a byproduct of turning raw wood into manageable sized lumber.
Due to their standard size, pellet stoves can be designed to burn their fuel more precisely, so the combustion produces less harmful smoke. Due to their standard size, pellet stoves can be fueled from a hopper, and automate the longer term management of a large supply of pellets.

Retrieved on 2021-03-12. “Pellet stoves offer a more environmentally sustainable choice for homeowners; the units burn recycled sawdust that’s been compressed and dried. You fill a hopper with pellets, set the heat level, and the stove automatically ignites. An electrically powered auger continuously feeds the pellets into the stove’s firebox.”

Retrieved on 2021-03-12. “But if you can’t switch to an automated wood heat system, you can still reduce your greenhouse gas impact by using a conventional pellet stove, which helps you reduce your fossil fuel consumption. In either case, using wood pellets from northern New England or New York is key; their climate impact is less than pellets from elsewhere that are transported long distances to the mill and to the end user.”
