Cardboard Recycling by-product

A large Montana container manufacturer recycles old cardboard containers
(OCC). About 8% of the total is rejected because of contaminants (plastic,
polystyrene, etc.). More than half of this reject stream (about 15
tons/day) is burned, the rest (about 10 tons/day) is non-burnable and is

Citizens are concerned about the burning because of plastics in the reject
stream, generally comprised of:

   69% fiber
   29% plastic
    2% other (e.g., polystyrene)

The company is investigating other options including landfilling. Does
anyone know of alternative uses of such a by-product, or have ideas about
reducing same? The company rep claims that, at a 92% yield, they are
already very efficient and can't think of ways to reduce this waste stream.
I'd love your help in convincing him otherwise...

Any info appreciated.
