Increases nutrient, minerals and energy output of base square
Specifically, the Recycling Tanks provide +1 each to Nutrients, Minerals and Energy in your base square. This may not sound like much, but consider the price and how early it comes in the game, and the value of the tanks becomes manifest. In fact, in a real sense you can't afford to be without it ( it pays for itself in 40 turns, and everything after that is pure profit ). In the early game you need every resource point you can scavenge, so you need the tanks. In the late game you have lots of facilities multiplying your final resource output, so you need the tanks.
The Pressure Dome gives you
the same bonus to your base square as the Recycling Tanks, plus protecting your
base against submersion. You may want to build the Pressure Dome instead of the
tanks, just in case, but the Pressure Dome is twice the cost (80).
