There are 3 or 4 (Alameda County, CA) manufacturers of milk and beverages
that generate 2 to 5 tons (empty w/ milk residue) of milk cartons per month
at the factory. These are contaminated pre-consumer cartons easily
collectable at source that currently are being disposed off as you-know-what
and going-to-you-know-where. We have been trying to set a process going to
get these on a milk run so that its worth the effort of the collector vendor
in terms of volume. It has been slow going ... while the cartons age and
mold and are no where near recyclable.
