🆕 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 Advanced Smelting Skill Book is a research item that unlocks the Advanced Smelting specialty when studied at a Research Table. Once crafted, right-clicking the book produces skill scrolls that teach the specialty to other players, with no limit on the number of scrolls one book can spawn. A practical tip: since one book supplies the entire server, coordinate with your townโ€™s researcher to craft it early so smelting specialists can share scrolls, accelerating industrial progress.
