Minecraft – How to automatically get combustable items

minecraft-java-edition

My friend made a machine that automatically farms cactuses and I was wondering if there is any combustable items that can be farmed without human intervention?

I discussed this in a chat before, the topic back then was keeping a furnace busy forever. My research results were that the only smeltable items that could be farmed fully automatically, meaning with no player even being on the server, were raw chicken and cobblestone.
And no fuel item was farmable fully automatically. That was in July, since then a few smeltable items and fuel items were added, but you still can't fully automatically farm a fuel item.

So what is the next best thing? Random ticks and mob spawning. They happen in a big radius around players, so you would just need one player being in the area, who does regular player stuff or sits at a different farm or whatever.

The fuel items that only depend on random ticks or mob spawning are:

  • Bamboo
  • Coal (from wither skeletons)

(One funny alternative would be banners from pillager raids. But they require you to at least punch them yourself.)
