Marci / Tom,
In Illinois disposable sorbent products and rags are considered a solid
waste (regulated) and also meet the definition of a "special waste" due to
being an industrial process waste. They may also be considered a
characteristically hazardous waste. If the rags/sorbent materials are
disposed of they must be manifested according to IEPA Administrative Code if
they generate greater than 100 Kg/month*.
Rags and sorbent products which are laundered are not considered a solid
waste because they are not being abandoned or recycled and are not
waste-like. Since laundered towels do not meet the definition of a solid
waste in Illinois, they are not considered a regulated waste.
Note: Many laundry facilities will place restrictions on their (printer)
customers to remove
the solvents, etc due to waste water discharge problems they encounter
