Renewable Resources are resources that can be recreated indefinitely. While running out of resources isn't likely to be a factor due to theoretically infinite (and still quite vast in practice) map generation, this is a list of resources that can produced over and over without having to explore for more.
The listed Fully Renewable Products are items which can be crafted or smelted using only renewable resources. Note that TNT and arrows are created from a combination of renewable and non-renewable resources (being Sand and Flint, respectively).
Fully renewable resources
These resources do not require any nonrenewable items in order to be collected.
| Resource | Fully Renewable Products | Method |
|---|---|---|
| Saplings and Trees SaplingSapling SpruceSapling Birch |
WoodWood (Pine)Wood (Birch)Wooden PlankLaddersFenceFence GateWooden DoorTrapdoorSignWooden StairsWooden Pressure PlateCharcoal (Item)BedGold SwordGold PickaxeGold ShovelGold AxeGold Hoe | Trees can be grown from Saplings placed on lit Dirt; breaking trees' Leaves drops saplings. See Tree farming. Charcoal can be produced by smelting any kind of log. |
| Wool |
Bed | Obtained by shearing/killing Sheep, or by crafting 4 strings dropped by spiders. Six of the shown colors (white, light gray, gray, black, brown and pink) occur naturally in sheep; green, lime, red, orange and yellow wool require renewable dyes to produce. |
| Cobblestone |
ButtonStone BrickStone Brick Slabs | Let flowing Lava meet Water. (One should take care not to let the water come into contact with the lava source block, which will extinguish the lava to make obsidian.) |
| Crops |
Harvesting Crops may produce Seeds, which may be used to produce more Crops. May also be harvested from Tall Grass. | |
| Sugar Canes |

Renewable, but require nonrenewable resources
These resources require a one-time craft of a nonrenewable item in order to be collected. The resource then can be collected infinite times.
| Resource | Fully Renewable Products | Method |
|---|---|---|
| Water |
Two water spring blocks in the appropriate pattern produce a third; see Water for details.
However, harvesting it requires a Bucket, which can be used unlimited times, but is made of non-renewable Iron. | |
| Milk |
Obtained by milking Cows using a Bucket.
However, harvesting Milk for a cake requires 3 Buckets, which can be used unlimited times, but are made of non-renewable Iron. |
Renewable at the expense of nonrenewable resources
These Resources gradually consume uses of non-renewable tools when collected.
| Resource | Renewable Products | Method |
|---|---|---|
| Obsidian |
— | Entering a Nether Portal for which there is no matching exit will generate 14 free blocks of Obsidian(and 4 more "ledge" block if the portal is formed in mid-air). Only mining the corners(and "ledges") will keep the portal active.
However, harvesting it requires a diamond pickaxe made from non-renewable Diamond. |
| Leaves Leaves |
— | Harvesting Leaf blocks from grown Trees using Shears will produce leaf blocks instead of saplings.
However, harvesting it requires Shears, made from non-renewable Iron. |
| Vines |
— | Vines can be found hanging from leaves in Swamp biomes. They grow downwards.
However, harvesting them also requires Shears, made from non-renewable Iron. |
| Tall Grass |
— | Tall grass can be made by using Bone Meal on grass.
However, harvesting it also requires Shears, made from non-renewable Iron. |
