Resources
From Project Rebearth
Resources are the materials, currencies, and commodities that drive the economy in Project Rebearth. Players gather, process, trade, and consume resources to grow their settlements. There are 17 distinct resources grouped into five categories based on their role in the game.
Overview
Every settlement begins with a small stockpile of basic resources and must establish production buildings to sustain growth. Resources flow through multi-step production chains, where raw materials are refined into higher-value goods. The availability and efficiency of resource gathering depends on the biome where a town is founded, with each biome favouring different raw materials.
Storage is handled by dedicated buildings. The Center stores up to 5,000 of all standard resources, and can be upgraded to the Square with 10,000 capacity. Additional storage comes from the Warehouse (5,000 capacity, 1 worker) and smaller buffers on individual production buildings. Two resources, 
Coin and 
Knowledge, operate outside the standard storage system entirely.
Resources can also be bought and sold through the Trade system using the Market (1,000 trade capacity) or the Port (5,000 trade capacity).
Raw Materials
Raw materials are gathered directly from the landscape. Each biome specialises in one primary raw material, and gathering efficiency varies significantly across biomes. These resources serve as construction materials and inputs for production chains.
| Resource | Primary Source | Used In | Storage |
|---|---|---|---|
 Wood |
Woodcutter, Saw, Nursery, Tent, Foraging Hut | Construction (all biomes), housing upkeep, Tools Workshop input | Center, Square, Warehouse, Woodcutter, Logpile, Foraging Hut |
 Stone |
Quarry, Stone Crane, Improved Stone Crane, Foraging Hut | Construction (Stone Biome), Road, Plaza | Center, Square, Warehouse, Foraging Hut |
 Earth |
Claypit, Clay Crane, Improved Clay Crane, Foraging Hut | Construction (Earth Biome), Glassworks input | Center, Square, Warehouse, Foraging Hut |
 Ore |
Iron Mine, Improved Iron Mine | Refinery input | Center, Square, Warehouse, Iron Mine, Improved Iron Mine |
The Foraging Hut is unique in that it produces 
Food alongside a mix of raw materials that varies by biome.
Food & Agriculture
Food and agricultural resources sustain the population and feed production chains. Food is consumed by every housing building and the Center, making it the most critical resource in the game.
| Resource | Produced By | Consumed By | Storage |
|---|---|---|---|
| Food |
Field (potato, cow), Fishery, Boat, Foraging Hut, Bakery, Creamery | Housing (upkeep), Center, Square, Market Stalls, Expeditions | Center, Square, Warehouse, Fishery, Bakery, Creamery, Foraging Hut |
 Grain |
Field (grain, maize) | Windmill, Brewery | Center, Square, Warehouse, Windmill |
 Flour |
Windmill, Improved Windmill | Bakery | Center, Square, Warehouse, Windmill, Improved Windmill, Bakery |
 Milk |
Field (goat, cow) | Creamery | Center, Square, Warehouse |
 Wool |
Field (sheep) | Tailor | Center, Square, Warehouse |
Running out of Food triggers the Food Shortage event, which inflicts a severe Happiness penalty of -50%.
Refined & Manufactured
Refined resources are produced by processing raw materials or agricultural products. They are typically higher-value and serve specialized roles in the economy.
| Resource | Building | Input | Output | Storage |
|---|---|---|---|---|
 Drinks |
Brewery | Grain |
Drinks |
Center, Square, Warehouse, Brewery |
 Clothes |
Tailor | Wool |
Clothes |
Center, Square, Warehouse, Tailor |
 Metal |
Refinery | Ore |
Metal |
Center, Square, Warehouse, Refinery |
 Glass |
Glassworks | Earth |
Glass |
Center, Square, Warehouse, Glassworks |
 Tools |
Tools Workshop | Metal, Wood |
Tools |
Center, Square, Warehouse, Tools Workshop |
Tools occupy a dual role: they are both a manufactured product and a maintenance cost consumed by many production buildings (including the Woodcutter, Saw, Tent, Windmill, Bakery, Tailor, Brewery, Creamery, Glassworks, Refinery, Stone Crane, Clay Crane, Iron Mine, and their upgraded variants).
Trade & Specialty
These resources operate outside the standard storage and production systems, serving specialized economic functions.
| Resource | Source | Role | Storage |
|---|---|---|---|
| Coin |
Square, Market, Tavern, Market Stalls, Taxation | Currency for Trade, defense upkeep, research upkeep | Not stored in standard storage |
| Knowledge |
University, Museum | Choices activation, Expeditions cost | Not stored in standard storage |
 Scrap |
Expeditions | Upgrade currency for Improved Windmill, Improved Stone Crane, Improved Clay Crane, Improved Iron Mine | Center, Square, Warehouse |
Coin is consumed by Towers, Water Towers, Universities, and Museums, and is the medium of exchange in the Trade system. Running out of Coin triggers the Bankruptcy event.
Knowledge is required to activate certain Choices (such as Worker Safety, Intensive Farming, and Taxation) and to fund Expeditions.
Scrap is obtained exclusively from Expeditions and is used to pay the upgrade costs for improved building variants.
Biome Influence
The biome where a town is founded determines which raw material is most efficiently gathered and which material is used for construction.
| Biome | Primary Resource | Construction Material | Housing Wood Upkeep |
Notes |
|---|---|---|---|---|
| Wood Biome | Wood |
Wood |
Normal | Strongest Wood production
|
| Stone Biome | Stone |
Stone |
Normal | Strongest Stone and Ore production
|
| Earth Biome | Earth |
Earth |
~1/10th normal | Strongest Earth production; very low Wood upkeep
|
| Arctic Biome | None | Wood (2x cost) |
2x normal | No local raw material production; highest upkeep costs |
In the Earth Biome, housing Wood consumption is reduced to roughly one-tenth of other biomes, making it the most efficient biome for large populations. The Arctic Biome has doubled construction and upkeep costs in Wood and cannot produce Wood, Stone, or Earth locally through extraction buildings (the Woodcutter, Quarry, and Claypit are unavailable), though Food production via fields and fisheries still functions normally.
Production Chains
Resources flow through multi-step conversion chains. Each chain transforms lower-value inputs into higher-value outputs. The major chains are:
Bread Chain
Grain from fields is milled into Flour by the Windmill, then baked into Food by the Bakery.
Dairy Chain
Milk from goat or cow fields is processed into Food by the Creamery.
Tavern Chain
Grain is brewed into Drinks by the Brewery, then served at the Tavern for Coin.
Clothing Chain
Wool from sheep fields is woven into Clothes by the Tailor.
Glass Chain
Earth is smelted into Glass by the Glassworks.
Metal Chain
Ore is smelted into Metal by the Refinery, then forged into Tools by the Tools Workshop.
Storage
Most resources are stored in general-purpose storage buildings. Some production buildings also maintain small local buffers for their inputs and outputs.
"All standard" includes: Wood, Stone, Earth, Food, Grain, Wool, Milk, Flour, Drinks, Clothes, Scrap, Tools, Glass, Ore, Metal.
Coin and Knowledge are not part of the standard storage pool and have no capacity limit.
When all storage is full, the settlement becomes vulnerable to raids triggered by the storage-full event.

Other Sources
Scrap and a random basic resource ( Wood, Stone, Earth, or Glass) are obtained from Expeditions. Expedition yields scale with the explored area. All standard resources can also be obtained through the Trade system using Coin.
