🆕 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 Combustion Engine is a mid‑to‑late‑game component that burns fuel to produce mechanical or electrical power, forming the core of many advanced machines. It is crafted at a relevant station and is an ingredient in the Chainsaw, Combustion Generator, Industrial Barge, Industrial Mill, Modern Rock Drill, and Truck. Because combustion generates pollution and CO₂ that degrade the shared environment, a town should plan its engine‑based industry carefully—balancing rapid production against the ecological cost that can reduce everyone’s housing value and food supply.
