Composter

Produces fertilizer from compostable items.

The Composter is a work station in Rust with 500 health. You can craft it without a workbench, and its blueprint costs 10 scrap to research.

About the Composter

Outside a tool cupboard's range it holds for 2 days, then decays from full health to nothing in 4 days.

Only one vendor sells it: the Farming for 30 scrap.

How to raid the Composter

Its cheapest raid is 2 × Satchel Charge, 960 sulfur in all. Each of these also brings it down from full health: 1 × Timed Explosive Charge and 2 × Rocket. That count assumes no duds, and a Satchel Charge fails to go off 20% of the time.
