🆕 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

Advanced Smelting is a Tier 4 Smithing specialty that unlocks the production of steel—a critical material for mid-to-late-game machinery, construction, and infrastructure. Mastering this skill grants access to a variety of steel blocks, doors, signs, and the Barrel, as well as the Advanced Smelting Upgrade module, which reduces resource and labor costs at smelting stations. A practical tip: prioritize learning Advanced Smelting once your town has a steady iron supply, as steel unlocks higher-tier buildings and industrial upgrades that accelerate progress toward stopping the meteor.
