🆕 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

Composite Joshua Lumber is a high-tier building block (tier 5) crafted from wood and plastic, making it one of the most advanced construction materials in the game. It is used in crafting essential end-game structures such as the Computer Lab and Modern Upgrade 3, as well as high-end furniture and mounts. Because it offers the highest room value and enables the best crafting upgrades, stocking this material is important for a settlement's late-stage progression.
