Compost Bin — Detailed Guide
Turning thatch and feces into fertilizer
The Compost Bin is a farming structure in ARK: Survival Evolved that converts Thatch and feces into 
Fertilizer. In the game's words, it is "A large bin for converting thatch and dung into high-quality fertilizer." The ARK Wiki notes that Fertilizer supplies substantially more fertilization than feces do.
How a batch works
Put 50 
Thatch and 3 
Feces into the bin's inventory. The droppings can be of any size, and they do not have to match. After around one and a half in-game days, roughly 50 minutes, the ingredients are gone and 1 Fertilizer has taken their place.
- Composting 3 Feces always yields more fertilization than they would give directly, except with
Massive Animal Feces. The wiki recommends composting smaller feces and putting larger ones straight into a Crop Plot. - A single Massive Animal Feces at a ratio of 50 Thatch yields as many as 5 Fertilizer.
- The bin has 8 slots, enough for 2 Fertilizer at the 3 Feces to 50 Thatch ratio, but it makes them one after the other, never at the same time.
- Taking out the minimum required amount before the conversion finishes resets the timer.
- Inside the bin, the spoil time of feces is multiplied by 10, the same as on creatures.
Other ways to get feces and fertilizer
A 
Phiomia force-fed 
Stimberry produces 
Medium Animal Feces in large amounts. On Aberration, the hallucinations from poisonous red mushrooms make a player defecate over and over, quickly giving enough for several Fertilizer. A tamed 
Dung Beetle with feces in its inventory creates Fertilizer on its own, plus Oil as a byproduct, and the wiki rates it as more effective than the bin.
Building the bin
The engram unlocks at level 15 for 6 engram points. The bin is crafted in the inventory from 50 
Wood (or 
Fungal Wood), 15 Thatch and 12 
Fiber; a craft takes 5 seconds and gives 6.0 XP. It weighs 4 and stacks to 100. Our records list it on 12 maps, and 60 crate types can contain it, for example Aberration White. Counted as a thatch structure, it takes damage from every source apart from non-explosive ranged attacks.
