This mod adds a Spoilage Petrification recipe that allows converting a large amount of spoilage to a modest amount of stone.

This recipe is unlocked with the Artificial Soil technology. The recipe is available in the Biochamber and assemblers, as well as by hand.

This is my first time modding anything, and this seemed like a quick and dirty solution for what I was after. I don't imagine it will have any notable conflicts because of the simplicity of of the mod; but let me know. I guess.
