How to Make a Composter in Minecraft

Composters are one of the most useful farming tools in Minecraft. A composter block lets you recycle plant matter and food waste into bone meal, a renewable fertilizer that accelerates crop growth and supports sustainable farming.

Players use composters to turn biological material into bone meal, automate farms with hoppers, and trade with villagers. Farmers in villages rely on composters as their workstations, making them essential for trading crops and earning emeralds.

The importance of composters lies in their simplicity. Crafted with wooden slabs in a U shape, they provide nearly the same yield of bone meal as other fertilizer sources but are renewable and easy to automate. Learning how to make a composter in Minecraft is a vital step for efficient farming.

A composter block is a utility block that converts compostable items into bone meal. It has block states that change as the compost level increases. The composter's fullness increases as food and plant items are added, raising its internal level and potentially affecting redstone output, such as the strength of a comparator signal.

When composting is complete, the block reaches the final stage and bone meal is produced.

Composters play a role in farming and villager professions. Farmers use composters as their job-site blocks, and composters generate structures found in villages. Composters have been added to both Java Edition and Bedrock Edition, with only minor differences in automation and villager behavior.

To craft a composter, you need seven wooden slabs. Place them in a U shape in the crafting table: three slabs across the bottom row, two slabs on the middle row, left and right slots, and two slabs on the top row, left and right slots. This recipe moved composter blocks into the game as a simple crafting option.

Supported wood types include planks and slabs. Oak, birch, spruce, jungle, acacia, dark oak, mangrove, cherry, and bamboo wooden slabs all work. The composter item is identical across all editions.

In Java Edition and Bedrock Edition, the recipe is the same. The block's direct item form is a giveable item identical to a tile in Creative Mode.

Using a composter involves successfully adding compostable items. Each item increases the compost level. Compost changes appearance, indicating fullness, and compost texture updates with each stage.

When the composter reaches the final compost level, bone meal is produced. The emptied block then resets to the default value, ready for more compost. Composting completes block states show appearance, indicating fullness.

Villager interaction is important. Farmers use composters as their workstation. Composter pull and composter push mechanics enable automation with hoppers. Entities and items can only enter or exit the composter through the top, not the sides or bottom.

You can add plant-based items such as seeds, crops, plants, and food items. The composting chance varies by item tier. Melon slices, pumpkins, bread, and hay bales have a higher chance of composting. Potatoes produce more compost, but poisonous potatoes are a notable exception.

Items that cannot be composted include meat, fish, and rotten flesh. Dead bushes and other materials, such as biological matter with no chance of composting, cannot be added.

The best things to compost for efficiency are melon slices, pumpkins, and bread. The following table shows the composting chance per item tier.

A composter converts organic waste into bone meal. Bone meal is used for planting crops, specifically to speed up growth and support sustainability.

The composter block functions as a villager workstation. Farmers rely on it for trading. Composters support automation with hoppers, allowing bone meal to be collected automatically.

Composters are working block components that can be integrated into farms.

The chance of composting per item tier determines success. Compost level increases with each item. When the composter's fullness increases to maximum, bone meal is produced.

Fill subtitles and break subtitles indicate composting stages. A partially filled composter shows compost inside, with an empty interior until the composting is complete.

The hopper directly below the composter automatically collects bone meal. A downward-facing dropper can add compostable items. Comparator outputs a comparator signal strength depending on the compost level. The comparator can detect the composter's fullness only if there is no unpowered solid block between them.

Automatic composters use hoppers to feed items into the composter. Hopper directly below collects bone meal. Composter pushes and composter pulls mechanics allow automation.

An example setup involves planting crops, specifically adding compostable materials through a hopper and collecting bone meal in another hopper below. This creates more compost efficiently.

Automatic composters can be placed on farms and connected to redstone component systems.

Composters aren't just crafted; they can also be found naturally generated in the Minecraft world. These composter blocks often appear on village farms, at trail ruins, and occasionally in other structures, such as abandoned mineshafts or shipwrecks. When a composter is generated naturally, it provides players with a ready-to-use resource for turning biological material and plant-based items into bone meal, without the need to craft one from wooden slabs.

A naturally generated composter may appear partially filled, with compost inside and a compost texture that reflects its current compost level. The appearance indicating fullness is easy to spot: when the composter is nearly full, you'll notice a slight dip on top, and as composting progresses through the block stages, the compost changes appearance. This visual cue helps players know when bone meal is ready to be collected.

When interacting with a composter generated in the world, players can break the block using any tool or even by hand. When broken, the composter drops as an empty block, meaning the compost inside is not dropped and must be collected before breaking. The block's direct item form is identical to a crafted composter, making it a giveable item identical tile in Creative Mode. In Java Edition, the metadata bits default value for a naturally generated composter is set to 0, indicating an empty interior and default block states, ready for use.

Functionally, naturally generated composters work just like those you craft. They support the placement of compostable items, and as you add more compost, the composter's fullness increases. When the composter reaches the final time and is full, composting is complete, and block and bone meal are produced. The composter can also be integrated into redstone component systems, with comparator outputs and comparator signal strength emitted depending on the compost level, up to a maximum of 8 when full. This makes them useful as a power source or for automation, especially when paired with a hopper directly below or a dropper directly above.

Using naturally generated composters is a great way to save field space and resources, especially in survival mode. Players can focus on planting crops specifically and automating their farms, knowing that these working blocks provide nearly the same yield of bone meal as crafted ones. Whether you're looking to maximize your farm's efficiency or want more compost for your crops, taking advantage of the composter's natural generation is a smart strategy in all editions of Minecraft.

By understanding where to find and how to use these composters, you can streamline your farming operations, automate bone meal production, and make the most of every biological material you collect.

In Java Edition, composters have block states and metadata bits with a default value. Composters can be automated with hoppers and comparators. Composters can be found in villages as a natural generation.

In Bedrock Edition, composters have nearly the same yield and identical mechanics. Minor differences exist in villager behavior and automation. Composters are supported on PC, console editions, and mobile.
