⚠️ Eco v0.14 is coming — the next major update reworks upgrade modules, so some of these numbers will change. They reflect the current version. What’s changing →
  • Simpler tiers: the 1–4 tiered upgrades become a single Basic / Advanced / Modern upgrade each.
  • Permanent upgrades: a module placed in a workstation is permanent — no more swapping lower tiers out as you progress.
  • Power transitions: a module can change a station’s power type/draw (e.g. a Modern upgrade moves a sawmill from mechanical to electrical power).
  • Talent-integrated: modules now use the same bonus/talent system — any talent benefit (power, labor cost, recipe unlocks) can come from a module.
  • Cheaper to upgrade: with the multi-tier parts gone, fully upgrading a workstation costs significantly less.

We’ll update this calculator shortly after the update releases.

Tailings

Tailings

Waste product from concentrating ore. When stored improperly the run-off will create pollution; killing nearby plants and seeping into the water supply. Bury deep underground to help neutralize the effect.

Notes

Tailings are a waste block produced when concentrating dry iron ore. If left on the surface, they emit ground pollution that kills nearby plants and contaminates water. To neutralize this effect, tailings should be buried deep underground, where their pollution impact is reduced.
