🆕 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 Butchery Skill Book is a crafted research item that unlocks the Butchery specialty when used at a Research Table. It is produced by its own recipe and belongs to the skill-book category, meaning one book can generate unlimited skill scrolls for other players. Since scrolls are infinite from a single book, a server generally needs only oneโ€”the researcher can produce and distribute copies so every player can access the Butchery tree without each crafting a separate book.
