🆕 Updated for Eco 14 — “Garbage & Recycling” — this server and these numbers now reflect the new version. What changed →
  • Byproducts: nearly every recipe now leaves waste behind, so recipe pages list byproducts alongside ingredients.
  • Garbage & recycling: waste sorts from mixed garbage down to pure materials, and can be recycled back into stock.
  • Pollution has four kinds: acid rain, chemical, soil and heavy mineral, each settling into the ground differently. Pollution guide →
  • Modules reworked: upgrades are now Basic / Advanced / Modern / Specialty, one per slot, driving the same bonus system as talents. Module guide →
  • Fresh water: machines need it — water drawn from the ocean has to be desalinated first.

Notes

Screws are a pointed metal fastener, crafted from metal bars, that serves as a fundamental component in many advanced industrial machines and structures. They are used in recipes such as the Assembly Line, Blast Furnace, Boiler, and Composite Lumber workstations, making them a high-demand intermediate product for mid-to-late-game industry. Because screws appear in so many critical builds, maintaining a steady stockpile is wise to avoid production bottlenecks when expanding your factory.
