Where the captains are exactley puting them I do not know, but in the trash is a lot more secure than on a lap-top that gets stolen. At least someones gonna have to dig through a SH** load of stuff before they find anything. then, if the release is still readable, that person would have to be able to read and understand the data on it. This is a long shot scenario as opposed to stealing someones lap-top and reading the microsft excell file labled "airport gate codes".
