From Interstellar Rift Wiki
Disposal Unit
Overview
This interior device is mounted to an outer wall of your ship, and allows disposal of any unwanted item into space, or launching beacons and drones. In order to place it into your interior, it will have to be even with, or beyond the outer edge of the deck layout and those of adjacent levels. You can place exterior blocks to within one block of it.
Disposal Function
Simply walk up to the unit and press E to launch the inventory selected item to space. If you throw away something important, you may be able to recover it by using the Salvage Unit.
Beacon & Drone Launcher Function
The Disposal Unit also allows the launching of the Beacon, Defense Drone and Repair Drone items in the same manner as described above. You may also recover these items for later use with the Salvage Unit.
