}}A '''composter''' is a [[block]] that converts some biological material into [[bone meal]]. It also serves as a farmer [[villager]]'s [[job site block]].

== Obtaining ==
Composters can be broken using any [[tool]], though an [[axe]] is the fastest. The composter does not retain the compost inside; instead, it drops empty.

}}

=== Natural generation ===
Composters generate in [[village]] farms.

== Usage ==
Composters can be used to recycle [[food]] and plant [[item]]s (excluding [[bamboo]]<ref>{{bug|MC-142452|||WAI}}</ref>, [[poisonous potato]]es<ref>{{bug|MC-142373|||WAI}}</ref>, [[dead bush]]es<ref>{{bug|MC-219904}}</ref>, [[meat]], and [[fish]]) into [[bone meal]]. To do so, the [[player]] must {{ctrl|use}} any of a selection of items on the composter. When an adjacent [[redstone comparator|comparator]] is facing away from the composter, a comparator signal strength of up to 8 is emitted depending on the fullness of the [[block]].
Composters appear to have an empty interior. As such, [[entity|entities]] can enter and exit a composter through the top, but not the sides or bottom. The composter has a "floor", whose height depends on the fullness. When the composter is completely empty, this floor is slightly above the block below, and when it is completely full, there is a slight dip on top. When the composter’s fullness increases, any entities inside are pushed up accordingly‌.{{only|bedrock}}

=== Composting ===
The composter can be filled with compost, which is done by adding compostable [[item]]s to it. When successfully adding an item, a green [[particle]] ([[File:Glint (texture) JE1 BE1.png|25px]]) appears. The table below lists supported items, which have different levels of compost-ability. The higher the percentage of an item, the more likely it is for it to add another layer of compost. Each layer of compost has a [[podzol]]-like appearance. When the composter reaches the 7th layer of compost, the compost changes appearance indicating that [[bone meal]] can be collected by {{ctrl|using}} the composter a final time.

The following table shows the [[item]]s that can be used in a composter, the percent chance for an item to add a level of compost, and the average number of items needed to fill a composter. Smaller pieces (individual pieces of wheat, melon slices, etc.) produce more compost than the blocks or other items that can be made from them.  The exception is cookies, because each recipe produces 8 cookies, and together those give more than 3 times the compost.

=== Changing profession ===
If a [[village]] has a composter that has not been claimed by a [[villager]], any resident villager who has not already chosen a [[job site]] block has a chance to change their profession to farmer.

=== Redstone component ===
{{see also|Redstone circuit}}

A composter can act as a power source for a [[redstone comparator]]. With a composter behind it (either directly, or separated by an unpowered solid [[block]]), a comparator outputs a signal strength between 0 and 8, proportional to how full the composter is: 0 for empty, 1 for {{frac|1|7}} full, 2 for {{frac|2|7}} full, and so on to 6. 7 is for completely full but the [[bone meal]] is not ready to collect, and 8 for completely full and the bone meal is ready to collect. However, if there is a [[block]] between the composter and comparator, the comparator does not immediately update.

=== Hoppers ===
Composters can interact with [[hopper]]s. A hopper directly below a composter pulls [[bone meal]] from it. A hopper or dropper facing downward directly above a composter pushes [[item]]s into it. See {{slink|Hopper|Redstone component}} for more details.

Hoppers cannot interact with the sides of a composter.

=== Fuel ===
A composter can be used as [[fuel]] in a [[furnace]] to smelt 1.5 [[item]]s.

=== Note Blocks ===
Composters can be placed under [[note block]]s to produce "bass" sounds.

== Issues ==
{{issue list}}

== Trivia ==
* The compost texture is based on the [[podzol]] texture.
* If planting crops specifically for composting, potatoes produce somewhat more than beets, carrots, or wheat. However, melons offer nearly the same yield per field space, and do not require replanting after harvest.
