	If an inserter is holding an item that spoils, it will immediately turn and attempt to insert the item in its destination. Note that this overrides the general rule of [[stack inserter]]s that they only turn when they have a full hand size. This is done to prevent stack inserters from getting stuck.

			=== Spoilage & [[Quality]] ===
			When an item spoils, its spoiled product has the same [[Quality]].

	Spoiling can happen at ''any'' time. It can happen while an item is in a chest, in the input or output slots of a machine, in the hand of an inserter, etc. Almost nothing can arrest the process of spoilage.		Spoiling can happen at ''any'' time. It can happen while an item is in a chest, in the input or output slots of a machine, in the hand of an inserter, etc. Almost nothing can arrest the process of spoilage.

			Most items max spoil time increases with quality. Higher quality items usually take longer to spoil.

	For most spoilable items, their freshness matters only in that the freshness can transfer during production. For [[agricultural science pack]]s however, there is an additional effect. Freshness affects the science ~~value produced by a lab when the~~ pack is ~~being~~ consumed. ~~As such, a pack that is consumed while~~ 50% fresh will only ~~generate 50%~~ the science ~~value of~~ a 100% fresh ~~science~~ pack.		For most spoilable items, their freshness matters only in that the freshness can transfer during production. For [[agricultural science pack]]s however, there is an additional effect. Freshness affects the speed at which a science pack is consumed in a lab. A 50% fresh pack will be consumed twice as fast. But because it does not generate more science value during that consumption, it effectively only produces half the science that a 100% fresh pack would.

	Note that freshness does not affect the fuel value of any spoilable that has a fuel value. So long as the fuel is consumed before it spoils, it will impart all of its energy to the device.

	If an inserter is aimed at a machine which has trash slots based on spoilable input items, and the item it attempts to insert into the machine spoils before insertion is complete, the inserter will insert the item into the machine's trash slots. It will ''not'' do so if the item has spoiled before it was picked up (and it will not pick up spoiled items).		If an inserter is aimed at a machine which has trash slots based on spoilable input items, and the item it attempts to insert into the machine spoils before insertion is complete, the inserter will insert the item into the machine's trash slots. It will ''not'' do so if the item has spoiled before it was picked up (and it will not pick up spoiled items).

	If a machine's output is full, then spoil-based trash slots don't function. If input or fuel stacks spoil, they will remain in the those locations (blocking further inputs or fuel) until the machine's outputs have been emptied. In particular, this can affect [[captive biter spawner]]s. Eggs kept in the spawner do not spoil, but this can put the spawner in the "output full" state. If the [[bioflux]] fuel spoils, it can block new bioflux from being inserted into the machine.		If a machine's output is full, then spoil-based trash slots don't function. If input or fuel stacks spoil while in this state, they will remain in the those locations (blocking further inputs or fuel) until the machine's outputs have been emptied.

	[[Lab]]s and [[biolab]]s have pass-through logic that allows science packs to be passed from one machine to another. While this works for [[agricultural science pack]]s, it does not work for spoilage. So each lab must have its own inserter specifically to remove any spoilage.
