[Recipe] Digestate + Slag Crushed = Dirt

As you can see in the picture, we already have this recipe with Gravel. It would be nice to have another way to dispose of excess Slag.

Arguable. Dirt form a farmable land. Slag might be toxic. I woudn't grow my french-fries on the pile of iron smelting industry' waste. I'd rather dump it into ocean to ensure no fishes alive to bother my pollution-mutated colonists willing to have a relaxing swim after 3 shifts of work.

Had not considered the toxicity of the Slag.
