Today's near-zero-waste sawmills use computers and sophisticated equipment
such as laser-guided saws to get the most lumber out of each log. In fact,
today's mill recover about twice as much lumber from each log as did mills
at the turn of the century.
The wood fiber that is not usable as lumber is recovered and processed
into other valuable products. These "by-products" of lumber
manufacturing can become particleboard , oriented strandboard paneling,
or other engineered-wood products. Byproducts are also used to fuel cogeneration
plants which produce electricity for the sawmills. And wood fiber also is
used to make such products as plastic filler, shoe polish, toothpaste, varnish,
foam rubber, and much more!
