What is a Composter and What Does It Do?

This special block lets you recycle various plant materials. Its main function is converting organic matter into bone meal - a fertilizer that speeds up plant growth. Instead of obtaining bone meal from skeletons, you can simply process your organic waste using this block.

Additionally, placing a composter next to an unemployed villager will turn them into a Farmer. This allows trading for useful items like bread, potatoes, and even golden carrots.

How to Craft a Composter

First, you'll need to create wooden slabs. Place any 3 wood blocks in this pattern:

You'll need 7 wood slabs to craft the composter. Arrange them on the crafting table as shown:

Now let's explore how to use this mechanism efficiently.

What Can You Put in a Composter?

The composter functions simply: the more items you add, the higher the compost level rises. When full, it produces bone meal. Each item has a specific chance to increase the compost level as shown below:

Success ChanceMaterials
30%All leaf types, sea pickles, seeds (wheat/beetroot/melon/pumpkin), saplings, kelp
50%Melon slices, tall grass, cactus, nether sprouts
65%Apples, pumpkins, flowers, potatoes
85%Bread, baked potatoes, cookies, hay bales
100%Pumpkin pie, cake

While you can use any of these, remember that lower-chance items require more quantity to complete the cycle.

How to Use a Composter

Simply right-click it while holding a compostable item. Each addition has a chance to increase the compost level. When full, the top turns white - adding one more item generates bone meal. There are seven filling stages, shown by green layers inside the block.

On average, you'll need 7-14 items to produce 1 bone meal.

How to Automate a Composter

To streamline the process, you can create an automated system with 2 chests, 2 hoppers, and 1 composter.

Place compostable items in the top chest - they'll transfer to the composter via the top hopper. When bone meal is produced, the bottom hopper delivers it to the lower chest. The system runs continuously while materials last!

The Minecraft composter isn't just an efficient recycling tool - it's essential for farming and villager trading. It's a tremendous time-saver, especially for crop growers and farm builders.
