Keep out of Landfill via Special Program:
Spread them out flat, outdoors (weigh them down so they don't fly away) and let them air dry until they are stiff. They should never be put in a pile, as depending on conditions they could spontaneously combust.  The dried rags should be stored in a small, airtight, non-combustible (metal) container (like a paint can) with a tight-fitting lid.
