Compostable Flesh
by Lagaffe
Compostable Flesh makes rotten flesh, a common drop from zombies, accepted by composters as a compostable item.
What it does
Rotten flesh is normally useless for composting, and this Fabric mod changes that. Players can place rotten flesh into a composter, where it has about a 65% chance of raising the compost level, a rate close to most vanilla compostable items. The mod is aimed at making the zombie drop more useful for agriculture.
Farmer villagers also treat rotten flesh like other compostable items, so they pick it up and carry it to composters. Because the change is only about composting, it does not alter how zombies drop flesh or how it is obtained. The mod is open source under the MIT License and runs on client and server, so the server and every player need it, along with Fabric API, which is required. Builds are published for 1.21.3 and 1.21.4, and the latest file, 1.1-mc1.21.4, was released on 2024-12-04.

Use cases
Surplus zombie drops

Who it’s for: Survival players who run farms and want a use for rotten flesh, and server owners whose villagers should handle it through their existing composter setups.
