Ugh. I hate being that guy, and I realize it's a meme, not science, but I can't leave it alone.

Composting doesn't get rid of metals, so you'd need a way to deal with them if you wanted to be safe.

also doesn't remove prion diseases

Not that I disagree with you, but it doesn't make sense that they are stable in soil given that they are proteins, and those are relatively quickly decomposing in soil.

(Don't) Ask me how I know.

a quick look at wikipedia will show you are wrong

"In 2015, researchers at The University of Texas Health Science Center at Houston found that plants can be a vector for prions. When researchers fed hamsters grass that grew on ground where a deer that died with chronic wasting disease (CWD) was buried, the hamsters became ill with CWD, suggesting that prions can bind to plants, which then take them up into the leaf and stem structure, where they can be eaten by herbivores, thus completing the cycle. It is thus possible that there is a progressively accumulating number of prions in the environment."
