What is Sawdust?

Up until about 40 years ago, most people would have considered sawdust a waste product of the wood industry. A by-product of sawing, milling, cutting, grinding, sanding, and routing wood with machinery, portable power tools, or hand tools, what to do with it after it was created was often seen as a problem. Some landfills even stopped accepting it. Eventually, great minds figured out that sawdust and other wood waste could be used in many thrilling ways, and could even become high-value products.
