Yes, soil additive, not composting material. That’s all I meant. I think the original question was could you compost a body and I said yes except the skeleton and then someone asked what if you grind it up and the answer is still you can’t really compost bone.
You can’t yourself, but if you heat the compost it’s possible.
Our city takes bones as well as dog and cat poo as well as a host of other stuff you can’t compost personally since it’s a heated above 55c and breaks down all that extra stuff.
Municipal compost is put through a tub grinder, which masticates everything to a fine degree. So even there, it’s not really the heat. They are just grinding it to the point where you can’t distinguish it from other bits of rock and silica in the soil.

Also, I’ve gotten my home compost over 160 degrees F which is considerably hotter. I mean the same pile that these bones have survived.
