How to Make a Composter in Minecraft

This guide will help you learn how to make a Composter in Minecraft.

Farming forms a big part of Minecraft, especially in the Survival mode. It can be used to harvest food that replenishes hunger points, and also provides base materials for several complicated recipes.

Just like farms in the real world, farming in Minecraft requires sufficient water and fertilizers. A Composter can help with producing fertilizer.

Let’s jump right in.

What is a Composter in Minecraft

In Minecraft, a Composter is a block that is used to convert certain types of materials into bone meal. Bone meal is crucial for fertilizing plants, as anyone who farms in the game will understand.

Required Items

In addition to a Crafting Table, you need the following to make a Composter.

  • 7 Wood Slabs of any type

How to Craft a Composter in Minecraft

Step 1 – Gather Ingredients

You require 7 Wood Slabs to make a Composter. You can make Wood Slabs from Wood. Approach any tree in Minecraft and use your fists or an ax to mine Wood. Then go to a Crafting Table. Place one Wood Log in the middle of the 3×3 grid to obtain 4 Wood Planks of the same type. Move it to your inventory. Close the Crafting Menu and reopen it. Then place 1 Wood Plank in each slot of the middle row of the grid. You will obtain 6 Wood Slabs.

Step 2 – Open Crafting Grid

Select a Crafting Table to open its 3×3 Crafting Grid. You must place the items in a specific pattern to obtain a Composter. In the top row of the grid, place a Wood Slab in the first and third slots. The middle row is exactly like the top row, with a Wood Slab in the first and third slots. In the bottom row, place a Wood Slab in each of the 3 slots. You now have successfully crafted a Composter!

Step 3 – Collect Composter

The Composter will appear on the right side of the Crafting Menu. Move it to your inventory.



As the name suggests the primary use of a Composter is to compost items that are dropped into it. You can recycle all plant and food items (except dead bushes, meat, fish, poisonous potatoes, and bamboo) and convert them into bone meal. Different items have different levels of compostability. The higher this compostability percentage, the more likely it is for you to add another compost layer.

When you successfully add an item in the Composter, a green particle will appear. When the Composter has reached the 7th and final layer, then its appearance changes a bit to indicate that bone meal can be collected. Each item has a different chance of adding a layer of compost, with smaller pieces such as individual melon slices, wheat, and mushrooms being better since they give you more of a chance to add a layer.


Hoppers can be used along with Composters. A Hopper that is placed just beneath a Composter automatically pulls and stores bone meal from the Composter. A Dropper or a Hopper that is placed directly above a Composter can drop items into it. The sides of a Hopper do not interact with Composters.

Redstone Comparator

A Composter acts as a source of power for a Redstone Comparatorwhen it is present directly behind a Comparator or is separated by a solid block that is unpowered. A Redstone Comparator produces a signal ranging from 0 to 8 strength. Zero depicts an empty Composter, while one depicts that the Composter is 1/7 full, all the way until 7 depicts that the Composter is completely full, but the bone meal is not ready to be collected. A signal strength of 8 depicts that the Composter is completely full and that the bone meal can be collected. This is useful as an indicator on a bone meal farm.


Since Composters are made of wood, they can be used as a fuel source for a Furnace. Composters can be used to smelt up tp 1.5 items.


  • Using individual items to fill a Composter is considerably more efficient than using something like hay bales. This is because although hay bales have a much higher compostability percentage, you are likely to raise the Composter’s level by just 1. Using 9 wheat items separately, however, gives you a chance to increase the Composter level by up to 9, with 5 and 6 being most likely.
