Sawdust

Sawdust is composed of fine particles of wood. This material is produced from cutting with a saw, hence its name. It has a variety of practical uses, including serving as a mulch, or as an alternative to clay cat litter, or as a fuel, or for the manufacture of chipboard. Historically, it has been treated as a by-product of manufacturing industries and can easily be understood to be more of a hazard, especially in terms of its flammability. It has also been used in artistic displays and as scatter. It is also sometimes used in bars in order to soak up spills, allowing the spill to be easily swept out the door. Perhaps the most interesting application of sawdust is in pykrete, a slow-melting, much stronger ice composed of sawdust and frozen water.
