A Matter Refinery purifies matter to be used for construction of new Objects, Rooms and Food Dispensers.

  • The matter refinery does not need oxygen in order to function and will not catch fire if built out in space. This technique may increase the risk of miner asphyxiation, however.
  • Multiple refineries increase the amount of matter you can have stored, and allow your miners to have multiple locations to drop off their matter.
  • You can acquire matter without a Matter Refinery by demolishing existing structures or derelicts.
