These dont work at all.
The reagent wouldnt use corpses, since they dont have a reaction class. The product is wrong, there is no ORGANIC item type in the game. You also have no container in the reagents, but want to force the product into a container, which doesnt exist. And you try to make 150 boulders, since you added a product dimension to it. Twice even, for the slime boulders as well.
The [EDIBLE_VERMIN][EDIBLE_COOKED][MEAT][IMPLIES_ANIMAL_KILL][ROTS] tags on your material template dont have any effects, because it depends on item type, not the material. A boulder of biomass, even with the meat and edible and rotting tags, will never be used in meals, rot away or be edible.
