Overview

The Compost Mod (Expanded Composting Rewards) is a comprehensive overhaul of the composting mechanic in Minecraft. Developed by yurisuika, this mod transforms the vanilla composter from a simple bone meal generator into a versatile recycling machine. By utilizing a data-driven loot table system, the mod allows players to receive a wide variety of resources—ranging from common dirt to rare diamonds—based on what they compost and the environment around them.

Unlike the vanilla system, which has a fixed output, this mod introduces logic that considers the player's location, the current weather, and the specific items being recycled. It is designed to be highly compatible with other mods and fully customizable via data packs, making it a staple for survival, skyblock, and realism-focused modpacks.

Frequently asked questions

How do I start using Compost Mod?

Place a composter and start adding compostable items to it as normal. The mod works with vanilla composters out of the box, replacing the default bone meal output with whatever composition you've configured (or the mod's defaults if you haven't changed anything).

What's a 'composition' and how do I create one?

A composition defines what item drops from the composter, how often it drops, and how many. You create compositions in the config file by specifying an output item, a chance percentage, and min/max quantities—each composition is a separate entry you can enable or disable per world.

Can I make different worlds have different compost outputs?

Yes. Compositions can be set to world-specific, meaning you define which outputs apply to which world folder. This lets you run multiple worlds on the same modpack with completely different compost rewards.

How do I make rare items like diamonds drop from the composter?

Create a composition with the diamond item as the output and set its chance to a low percentage (e.g., 1–5%). Adjust the min/max quantity to control how many diamonds drop when the rare chance triggers.
