🆕 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 Cement Kiln is an advanced crafting station that produces cement, reinforced concrete, fiber reinforced concrete, and sulfurcrete, and requires placement inside a Tier 3 room with at least 24 m³ of free volume. It emits 2.4 air pollution PPM per hour while running and accepts Advanced or Masonry Advanced Upgrade modules to reduce resource and labor costs. If your settlement is transitioning to concrete infrastructure, build this kiln inside a high-grade room to keep pollution manageable and maximize upgrade efficiency.
