Is There A use For.....?

Was wondering if there is a use for the fiber content that is left over after juicing.. seems such a waste... I live in an apt so a compost would not work for me.. has anyone ever dehydrated the stuff and then ground them up or something for a powdered form of nutrients for drinks??

edited... :( oh man is there a way to delete this post?? I just saw another post almost identical to this one... heavy sigh.... ok this newbie will start reading more and less posting for now... sorry
