Void Chest instantly destroys whatever is placed in it.

Simple, effective, and painless. Unless of course you accidentally place valuables in it.

My Original mod updated (resurrected more like) with the Void Chest + base which uses the base-game mechanics to clear the inventory.

Obviously a cheaty mod in Space Age.

v2.7.1 Has a fix for using these on space platforms. There is a separate event that fires when something builds there that wasn't being subscribed to.
