A protected mass of wood chips comprising a mass of wood chips wherein at least a substantial portion of the exposed surface is a cohesive fibrous mat comprising said wood chips bound by cellulosic fibrous material and gelatinized starch, said cohesive fibrous mat being essentially only on the surface of said mass of wood chips.
A method of protecting a mass of wood chips comprising:
- providing a binder composition comprising discrete particles of cellulosic fibrous material and gelantized starch;
- and
- applying said binder composition to the exposed surfaces of the mass of wood chips and contacting said binder composition with water to form a cohesive fibrous mat of wood chips bound by said binder composition, said cohesive fibrous mat being essentially only on the surface of the mass of wood chips.
