Sawdust or wood dust is a by-product of cutting, grinding, drilling, sanding, or otherwise pulverizing wood with a saw or other tool; it is composed of fine particles of wood.
Sawdust is the main component of particleboard. It has a variety of other uses, including serving as a fuel. Until the advent of refrigeration, it was often used in icehouses to keep ice frozen during the summer. It has been used in artistic displays, and as scatter.
Sawdust is also used in the manufacture of charcoal briquettes and pellets.
