About Decomposer
From Factorio Mod PortalIntroduces a building that recycles spoilage, breaks down agricultural resources, and utilizes specialized bacteria to bio-decompose solid rocks and ores into dusts.
Mod It introduces advanced organic and mineral decay mechanics, allowing you to cultivate specialized bacteria to either eliminate biological waste or break down geological resources into highly processable metal dusts.
- Decomposer: Unlocks the primary decomposer machine and the initial decomposition-bacteria culture. This loop lets you process raw-fish, spoilage, and water to kickstart and multiply your bacterial logistics.
- Organic matter bio-decomposition: Enables advanced biological processes to trigger controlled rotting and decompose agricultural products into spoilage. This allows you to produce fermented-fish to unlock more advanced and efficient cultivation recipes for your decomposition-bacteria.
- Organic sludge processing: Advanced processing of bulk rot into dense fluid organic slurry, allowing for highly efficient spoilage transport. It lets you turn spoilage into organic-sludge and condense it back when needed.
- Lithic bio-decomposition: Utilizes specialized bacteria to leach and erode minerals, breaking down solid stones and raw ores into fine, highly reactive dust. This process uses your decomposition-bacteria and water to erode stone, iron-ore, and copper-ore into sand, iron-dust, and copper-dust, as well as basic smelting into iron-plate and copper-plate.
- Metalic dust melting: Advanced metallurgy that allows you to melt iron-dust and copper-dust with calcite inside a foundry to get molten-iron and molten-copper.
