Minecraft wiki entry for Bamboo, associated text: Bamboo can be used as fuel in furnaces. Each bamboo item smelts 0.25 items. Crafting two bamboo into a stick and using that as fuel is equivalent, smelting 0.5 items. With the addition of string, it is more efficient to craft six bamboo into scaffolding, which can smelt 2 items in Java Edition or 6 items in Bedrock Edition, instead of 1.5 items from the original six bamboo.
