Are the ingredients available domestically? As opposed to Russia China or Africa?

Calcium can be found anywhere, is a component of limestone, chalk and marble.

China is the largest producer of antimony

The next step is to evolve the process to work on acrimony instead of antimony.

Once this occurs it’ll finally make sense why Elon purchased twitter and is a genius.

I don't know, with the way things are going with Twitter right now that purchase seems to be very anti-money.

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

Dammit, so still dependent on a less than friendly country
