🆕 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

Limestone is a common sedimentary rock used across construction, crafting, and industry. It is mined from deposits near the surface in Grassland and Desert biomes, requiring a tier-2 pickaxe, and serves as an ingredient in many early recipes including crushed stone, building blocks like Ashlar Limestone, and basic research papers. Because limestone can be minted into currency at a high rate, early players may consider stockpiling it as a valuable trade and monetary resource for the town.
