STRINGS.SUBWORLDS.RUST.UTILITY
When combined with the Rust Deoxidizer, Rust can produce many of a colony's basic needs.
The Squeaky Puft, a frequent resident of the Rust biome, is a renewable source of Bleachstone and can be domesticated for such purposes.
Dreckos can also sometimes be found in these biomes, which are a great source of Phosphorite and fibre for making Textile Production.
Two plants found in this biome, the Nosh Bean and the Dasha Saltvine, can both produce food that will add significant Morale value for my Duplicants.
