What is Composter in Minecraft?
The Composter has two main purposes in Minecraft. First, it serves as a recycling block, which is converting plant materials and food into bone meal. Second, Composters are farmer villagers’ job blocks.
You have every compostable item listed below.

Adding a compostable item to the Composter has a certain chance of producing a layer of Compost.
Green sparkles surrounding the Composter indicate that your attempt was successful and another layer of Compost was produced.
After successfully producing seven layers of compost, you can collect the bone meal.
Important
You can’t compost bamboo, dead bushes, poisonous potatoes, fish, and meat.
How to Make a Composter?
It takes seven wooden slabs to build a Composter, which is why you will need to use the crafting table with its 3 x 3 crafting area. It can be any slab.
Here you have a list of wood items that can be used to craft a Composter in Minecraft:
- Seven Oak Wood Slabs,
- Seven Dark Oak Wood Slabs
- Seven Spruce Wood Slabs,
- Seven Birch Wood Slabs,
- Seven Jungle Wood Slabs,
- Seven Acacia Wood Slabs,
- Seven Crimson Slabs,
- Seven Warped Slabs.
Why the lucky number seven? It takes one look at the crafting grid to know why.
Once you open your crafting table and put the required materials in a U shape. Leave the top middle square and the center square free.
Pro-tip
You can use any slab, as long as you have seven of them.
Why do you need a Composter in Minecraft
If you have seven wooden slabs to spare, you might as well fetch yourself a Composter. Its main function is to turn compostable items like plant materials into bone meal, which then serves as a fertilizer for crops.
Minecraft is a complex game with a plethora of items that may, or may not, be useful.
Eventually, you end up with a pile of junk in your inventory that you have no clue what to do with. Composter allows you to utilize them and free up some inventory space.
It is also, as we stated earlier, a job block for farmer villager.
What do I need a bone meal for?
A bone meal is definitely a cheaper way to feed plants than a Super Fertilizer. To craft Super Fertilizer you need Ammonia and Phosphorus. Obtaining them involves using an element constructor or material reducer.
When you compare it to dumping some plants into a wooden box, it sounds overcomplicated, even taking into consideration the fact that you need to use a bone meal multiple times.
Bone meal can be used to fertilize most plants. What’s more, you can use its products to prepare materials required for the production of dyes.
Minecraft’s Composter: Final Word
There is a saying: “Show me your garden, and I’ll tell you who you are.”
Ok, we made that one up but it is a common truth, that having a beautiful garden is a reason to boast. In order to make it efficient, you can’t waste a thing, especially in a world where ecology gains more and more recognition.
It is why many people use a composter to recycle waste and this idea is no different in Minecraft.
I hope this guide was useful and you will be able to make a composter in no time.
If you are into farming, it would totally make sense to put it somewhere around your Minecraft’s farmhouse - for inspiration, make sure to check our guide to Minecraft houses.
Now go collect some slab and make a composter!
