have recently gotten burnable trash. it is labeled as having a fuel value but will only enter furnace as item not fuel
The game has multiple kinds of fuels. I mean not the base game, which has just burnable fuel to my knowledge. But mods can add more categories.
So the "Burnable Garbage" items work with Waste Incinerators. But not with the typical buildings that take fuel like furnaces or boilers.
