🆕 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.

The character calculator has been updated for these changes. Read the garbage & recycling guide →

Notes

The Piston is a crafted component used in a wide range of advanced machinery, including engines, generators, presses, and pumps. It is produced through the Piston recipe and serves as an ingredient in many mid-to-late-game industrial devices such as the Combustion Engine, Electric Stamping Press, and Pump Jack. Because it appears in so many important recipes, players may find it efficient to stockpile or automate piston production for ongoing industrial needs.
