Angel59920- No such thing as a stupid question. If you don't know the answer and you WANT to know the answer, then don't be afraid to ask.
And Penny just so someone doesn't read your response and think that they "recycle" the waste for drinking water or something ...eeeewww The treated waste water from showers/ sinks and kitchen is converted into "grey water" and reused for washing decks and that type of thing. The sewage is treated until it is clean enough to be released and the solids may be burned... But I agree on catching the cruise documentaries on DSC or Travel Channel.
