Hi 1bluestar,
Welcome to the Support Communities!
Take a look at the article below. Deleting the user preferences should bring back the Aperture Trash in your sidebar.

You can resolve many issues by restoring Aperture back to its original settings. This will not impact your image files or your library. To reset your Aperture user preference settings to their original state, do the following:
- Quit Aperture.
- In the Finder choose Go to folder from the Go menu.
- Type ~/Library/Preferences in the "Go to the folder" field. Press the Go button.
- Remove the "com.apple.Aperture.plist" file from the Preferences folder.
- Restart your computer if you're using OS X Mavericks.
Note: The locations of your Aperture libraries are stored in the preference file listed above. If you have stored your library outside the default location of ~/Pictures/Aperture Library, make a note of where the library is before deleting the Aperture preferences file. If you have more than one library, you can bring up a dialog to choose which one to load by pressing Option immediately after you open Aperture.
Cheers,
- Judy
