⚠️ 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.

Wet Tailings

Waste product from concentrating ore. The run-off creates ground pollution; killing nearby plants and seeping into the water supply.

Notes

Wet Tailings are a waste product generated by concentrating ores such as copper, gold, and iron. They produce ground pollution (level 3 per block), which kills nearby plants and contaminates the water supply. Because careless surface dumping poisons the soil and reduces nearby housing value, tailings should be stored in a lined containment pit or buried in a remote area to limit environmental damage.
