Taken from Stationeers Stationpedia...
"the advanced composter creates fertilizer out of organic matter.
It accepts food, decayed food, or biomass. It requires water and power to operate, accelerating the natural composting process.
When processing, it releases Nitrogen and Volatiles, as well as a small amount of heat.
Fertilizer is produced at a 1 ratio of fertilizer to ingredients. The fertilizer's effects on plants will vary depending on the respective proportions of its ingredients."
| INGREDIENTS | EFFECT |
|---|---|
| Food | Increases Yield up to 2x |
| Decayed food | Increases Growth Speed up to 2x |
| Biomass | Increases Growth Cycles before the Fertilizer runs out, up to 5x |
Usage:
- Connect a H2O pipe with at least 20 mol H2O
- Connect power
- Insert at least 3 ingredients into the input slot on the side
- Turn on the On switch, it will grind the ingredients
- Point at the panel and it will tell you how many are ready for processing. You need at least 3 to produce 1 fertilizer
- Press the Activate button, and it will start processing, including outputting H2 and N2
- When done processing, a fertilizer will be ejected from the output slot More information:
- Constructed from the Kit (Advanced Composter) which can be produced in the Electronics Printer Mk. II (Tier Two)
Recipes
- 3 items of Food or Decayed food or Biomass (it will be consumed in the ratio provided, if there 10 food, 20 biomass: 1 food 2 biomass will be consumed)
- ~20 moles of Water
produces
- 1 Fertilizer
- 50 moles Nitrogen (at 45°C) (updated: 2025-01-21: from 4.9mols to 50)
- 50 moles Volatiles
The exact moles consumed or produced is slightly variable.
