The Orange Box: Portal Hints
How does the companion cube disposal process work?
1 of 5: First, you'll need to bring your cube into the area with you.
2 of 5: If you left it behind, go back and drop down to the floor of the big lift room, then get the cube and carry it along as you return to the cube disposal area.
3 of 5: Drop the cube on the big red button to open the door that leads to the incinerator's control button.
4 of 5: Go press the control button, then quickly run back to the cube.
5 of 5: Pick it up and drop it into the open incinerator device, which is near the door that the red button opened.
