What is a Composter and its Purpose?

This functional block allows recycling various plant materials. Its primary function converts organic matter into bone meal - a fertilizer that accelerates plant growth. Rather than obtaining bone meal from skeletons, you can conveniently process organic waste through this block. Additionally, placing it near an unemployed villager converts them into a Farmer villager, enabling trades for useful items like bread, potatoes, and golden carrots.

Crafting a Composter

First, create wooden slabs by arranging 3 wood blocks:

Crafting the composter requires 7 wooden slabs arranged on the crafting table:

The following section explains optimal usage techniques.

Acceptable Composter Inputs

The mechanics are straightforward: more inputs mean higher compost levels. When reaching maximum capacity, the composter yields bone meal. However, each item has specific success rates for increasing compost level:

Operating the Composter

Simply right-click while holding compostable items. Each insertion attempt may raise compost level. At maximum capacity, the composter turns white - adding one more item produces bone meal. Seven filling stages are visually represented by green layers.

Typically, 7-14 items yield 1 bone meal.

Creating Automated Composting Systems

For efficient operation without manual input, build an automatic system requiring 2 chests, 2 hoppers, and 1 composter:

Place compostables in the upper chest, which feeds items into the composter via the top hopper. Produced bone meal transfers to the lower chest through the bottom hopper - continuously operating while materials last!

The composter serves not just for recycling surplus materials but proves essential for farming efficiency and villager trading operations. It's particularly valuable for agricultural projects and automated farms.
