I visited a local paper recycling plant on Friday which handles consumer
waste milk cartons.   One of the materials that they were having problems
with was polycoat paper cups.  Apparently the ink used on these cups
is different from the ink used for milk cartons and was causing problems
in the de-inking and waste water treatment system (the plant has a
high recirculation rate).
