I found the following tip on about.com
Any time you peel vegetables like carrots or potatoes, or trim vegetables like celery or onions, scrub them first, then freeze the peelings and trimmings until you have a gallon or so.
Put it in a pot of water and cook until everything is done, then strain the solids and use the remaining broth for a soup base.
