It's also in bones and seashells, the former of which is almost certainly a byproduct of the animal agriculture industry.

It might be a good way to reduce waste.

Unfortunately not. Recovering the calcium from bones and seashells is extremely costly and labour intensive as the raw materials don’t contain it in the form you want to have it. At the same time we have huge ressources in all sorts of calcium rich minerals and you don’t have to worry about any organic contaminants.

But I could imagine we are using bone meal as fertilizer and calcium supplement
