From Essential Hacks (http://www.simania.nl/sdls/eh/sdls-eh.htm):

Buyable trashcan

For accidental deletions (use move_objects cheat to place outside lot boundaries). Or put a second trashcan in the house, for a receptacle that never needs emptying. (Unfortunately, your Sims may be too stupid to notice it... Never mind... Have patience.) Comes in two versions: MM and pre-MM. The catalogue text added is that of the HD trashcan, an identical-looking but different object.
