What do cruise ships do with human waste?

Cruise ships are only permitted to release human wastewater that has been heavily treated. Solid waste is also treated and dehydrated but not released into any open body of water. Instead, it is disposed of through standard, onshore waste disposal methods once the cruise ship is in port.
