The '''recycler''' is a building that can convert most items into the ingredients used in their recipes, at the cost of losing 75% of said ingredients. In other words, it performs a lossy reversal of crafting.

It has 4 module slots, but it cannot use [[Productivity module]]s.

== Mechanics ==

When an item enters a recycler, the item's main recipe is found, and the recycler is automatically set to perform its inverse.

For each type of item used as an ingredient in the recycled item's main recipe, the number of items returned by the recycler is decided by <code>floor(0.25 * i / o + r)</code>, where <code>i</code> is the number of items used as ingredients, <code>o</code> is the number of items returned by the recipe, and <code>r</code> is a random number that is greater than or equal to 0 but less than 1. On average, this returns exactly 25% of the items needed to craft one item of the same type as the recycled item. For example, recycling a [[processing unit]] always gives 5 [[electronic circuit]]s while having a 50% chance of returning one [[advanced circuit]].

All fluid ingredients are lost when recycling, as the recycler has no fluid output.[https://www.reddit.com/r/factorio/comments/16d7h82/friday_facts_375_quality/jzpac1z/]

Without quality modules, the resulting items have the same quality as the item being recycled, even if the latter was crafted using lower-quality ingredients. Quality modules can further increase the output's quality, just like with regular non-recycling recipes.

The recycler has 12 internal slots for its output, but can only hold one stack of each item. The recycler will try to eject the contents of these slots, much like a mining drill. It is therefore not necessary to use an inserter to collect its output.

=== Non-recyclable items ===
Some items, such as ores, have no recipe, and can therefore not be recycled. There are also some recipes that are irreversible, which include smelting and chemical processes.[https://discord.com/channels/139677590393716737/603392474458882065/1149692470511276152]

When an item with no reversible recipe is "recycled", then the same item has a 25% chance of being returned, and a 75% chance of being destroyed instead. This can be used to destroy unwanted items, such as byproducts from [[scrap recycling]].

Irreversible recipes include (but may not be limited to):
* Recipes performed in furnaces or chemical plants
* Recipes for science packs
* Recipes for [[uranium fuel cell]]s
* Recipes for [[biolab]]s or [[captive biter spawner]]s
* Recipes for spoilable products

=== Unique recycling recipes ===

Some items have unique recycling recipes:

* Recycling [[scrap]] will perform the [[scrap recycling]] recipe, for which there is no inverse, as scrap can not be crafted. This is used to obtain most resources on [[Fulgora]].
* Recycling one [[nutrients]] will yield 2.5x that amount of [[spoilage]]. This is useful for getting rid of excess nutrients, as they cannot be burned directly.

Recycler

SyndaKitty: Corrected scrap recycler rates. Rounded up for advanced circuit, low density structure, solid fuel, ice, holmium ore, and copper cable. This may be worth revisiting to provide 3 decimal places for those.
