🆕 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

The Rolling Mill is a tier-3 crafting station that processes steel into building materials like Corrugated Steel, Flat Steel, and steel doors and signs. It must be placed in an enclosed room with at least 24 m³ of free volume and accepts Advanced Smelting or Advanced Upgrade modules to reduce resource cost and craft time. Because it requires a tier-3 room, you will need high-tier building materials and furnishings before you can place it, so plan your industrial expansion to include a suitable workshop first.
