Sawdust

Sawdust is composed of fine particles of wood. This material is produced from cutting with a saw, hence it's name. It has a variety of practical uses, including serving as a mulch or as a fuel, or for the manufacture of chipboard . It has also been used in artistic displays and as scatter. Perhaps the most interesting application of sawdust is in pykrete, a slow-melting, much stronger ice composed of sawdust and frozen water.
