How do hotels dispose of 'slightly dirty' towels?

'Slightly dirty' towels go into the hotel laundry: we don't give up on them that easily. Towels are only retired if they show a stain that won't come out  or they start to get discolored or frayed. (If it's not too noticeable, we dye it blue and use it as a pool towel: otherwise, it gets dyed red and the housekeepers use it as a cleaning rag.)
