Compost

Compost safely processes biological waste and produces fresh Dirt. It is a simple waste-handling building that turns organic refuse into a useful building material instead of leaving it to clutter storage or rot elsewhere. Because its output is Dirt, Compost is most valuable on colonies that need a steady soil supply for farming, filtering, or general construction support.

In practice, Compost is best used as an early and reliable recycling option for biological byproducts. Any colony that produces a lot of organic waste can feed that material into Compost to keep the base cleaner while recovering a resource that is broadly useful throughout the game. Since the building’s purpose is straightforward, it fits well into a central processing area near other resource-handling structures.

• It is designed for biological waste, not for every type of debris.
• Its output is fresh Dirt, making it a source of farmable material and general-purpose soil.
• It is most useful when the colony has more organic waste than immediate storage needs.
• Placing it near the area where waste is collected reduces hauling time for Duplicants.

Compost is especially helpful in colonies that want to convert an otherwise inconvenient waste stream into a material that can be immediately used again. By turning biological waste into Dirt, it helps close the loop between consumption and production, supporting a cleaner and more efficient base layout.
