A Storage Compactor is a structure where excavated or harvested resources can be allocated, clearing debris from the ground and increasing overall decor opinion. While the compactors themselves decrease decor opinion by 10 for a two-tile radius, they greatly increase overall opinion by clearing the floor of clutter up to 20,000 kg. They do not require research to construct.

A menu appears when clicked, requiring the player to choose what resource they wish to store there before Duplicants will begin sweeping the floors of that resource and placing them inside. If a resource is placed inside and then the box allowing that resource inside is unchecked, the resource will drop onto the ground outside of the Compactor.
