Renewable resource

A renewable resource (as opposed to a non-renewable, or finite, resource) is a resource that can be recreated indefinitely in survival without exploiting glitches or using cheat commands. While running completely out of resources isn't likely to be a factor in normal worlds due to the massive size of a Minecraft map, only some resources can be produced over and over without having to explore more terrain. Running out of resources can be a bigger issue on superflat worlds, where resources are less plentiful, in PvP maps, where one would like to obtain resources without having to conquer more land, or simply if the map size is limited.

The listed fully renewable craftable items are items that can be crafted, smelted, or brewed using only renewable resources. For example, cookies are renewable as they only require wheat and cocoa beans which can be regrown infinitely, while TNT isn't because it requires sand, which is not renewable.

Anything that is dropped by an animal or most monsters, is renewable because more mobs of the same kind can spawn and be killed again for more loot. The exceptions are the wither, which requires non-renewable soul sand to spawn and certain enemies that only spawn once with the generation of specific structures; elder guardians (three spawn with each ocean monument), illagers (in woodland mansions), and shulkers (in end cities). Hostile monster drops are not renewable on peaceful difficulty, as the monsters won't spawn.

Introduction to methods of renewably obtaining items
Many resources are renewably obtainable using certain main methods, such as farming. Others are obtainable by unusual item-specific methods, which can vary from building a cobblestone generator to harvesting obsidian from portals to collecting dragon breath into a bottle. The renewable method to obtain an item isn't necessarily the easiest, fastest or safest.

The most common methods for renewably obtaining items, ordered by roughly increasing effort are:
 * Farming - grow it on the dirt or farmland block, breed using renewable resources, etc.
 * Crafting/Smelting/Brewing using only renewable resource(s)
 * Common drops from dead mobs.
 * Trading with villagers
 * Fishing
 * Rare mob drops.

The first three methods are often the most practical ways to obtain the items which can be obtained by using them.

Most items obtainable by the fourth and fifth methods are obtainable in some other way, which may be easier or of comparable difficulty, but may not be renewable, they are especially worth using when the player wants to avoid the risk of mining, such as while playing in hardcore mode.

Grinding for rare drops is generally only worth it when there is no other option, as the player will generally have to kill a lot of mobs before getting what they need.

Renewable
These are items which can be renewably obtained through methods other than trading or rare drops.

Tradable
These items are either only renewable through trading with villagers or additionally as rare drops from mobs.

Rare drops
These items are considered rare drops or are obtained by a mob dying in a unique way. For some of these items, this is the only way to even obtain them whatsoever, for the rest this is the only renewable way to obtain them. This does not include any item the mob picks up after spawning. Mob farms are a good option for obtaining these easily or in large quantities.

Renewable
These items are renewable only in snapshots and prereleases. They either do not exist, or are not renewable in the latest official release.

Bedrock Edition
Most resources are as renewable in the Bedrock Edition, as they are in the Java edition. The resources, which are renewable in Bedrock Edition, but aren't in Java are listed here, for the ones which are non-renewable in Bedrock Edition, but renewable in Java, see the Non-renewable resource page.

Legacy Console Edition
Most resources are as renewable in the Legacy Console Edition, as they are in the Java edition. The resources, which are renewable in Legacy Console Edition, but aren't in Java are listed here, for the ones which are non-renewable in Legacy Console Edition, but renewable in Java, see the Non-renewable resource page.

These resources are not renewable in the Java edition, but are renewable in the Legacy Console Edition.
