Invisiclues for "The Garbage of the Future"

First, some general tips:

• Light is helpful or required for many things. Make sure to have a working flashlight when exploring and doing things.
• None of the items are really meant to be hidden and can be found by exploring everything thoroughly. Most of the rooms have at least one thing in them you can interact with.

Warning! This contains many spoilers. To be consistent with the in-game achievements, check the achievements you've completed to reveal additional achievements.
