Virgin hardwood sawdust is frequently used for animal bedding.
Sawdust from soft woods is not, in addition to sawdust from
non-virgin (composite) types of wood waste (particle board,
veneered wood, plywood, etc.) or preserved woods.
This issue has created some differences between Department
environmental programs on management of non-virgin wood waste.
(PLEASE NOTE: WHEN I SAY "NON-VIRGIN" I'M NOT INCLUDING PRESERVED
WOOD WASTE CHEMICALLY TREATED WITH CREOSOTE, CHROMIUM COMPOUNDS,
Solid Waste folks tends to be more liberal with lumping virgin and
non-virgin wood wastes together for most re-use options. One
catch is that the composite woods should be in relatively small
proportions to virgin wood.
Air Quality does not like to see composite woods burned but will
okay virgin wood fired boilers.
Water Quality folk seem to get involved only if composite woods
are re-used in settings with exposure to the environment and
sampling shows leaching of chemical constituents.
Also note: Farmers use spent animal bedding as a soil
conditioner/fertilizer...i.e. it ends up in the fields for growing
crops. Even if the cows do or don't pick up contaminants, some
crops might, or they may end up in ground water.
