🆕 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.

Notes

Sharpening Steel is a crafted metal rod used for honing tools to a finer edge, produced via the Sharpening Steel recipe. It is tagged as both a Part and a Product, meaning it can serve as a component in advanced crafting or be sold as a finished good on the player economy. Storing a stack of Sharpening Steel is lightweight at 100 g per unit, making it easy to keep on hand for repeated sharpening needs. If you rely on high-tier tools, keeping a supply of Sharpening Steel in your stockpile ensures you can maintain peak tool performance without delays.
