I mean, I would like to farm, but I would also like just a normal pet gator that I don't eat. They do seem to be able to become more docile than other crocodilians and crocodilians are actually quite intelligent. If I were immortal then I'd be selectively breeding them to be proper pets like dogs and cats are. No real risk of them attacking their owner and would even come to love and seek affection from them.
As for jewelry I imagine there'd be some kind of workshop or manufactory for that and if I had to guess then I bet they sweep their floors to collect lost gold dust and gems.
I think for piranha solution it doesn't smell so bad since it's mostly just producing carbon dioxide. I don't think much sulfur is released with its use, but we'd need to consult one of the two chemist anons(seems 'guya is busy so it may be a bit, that or he forgor about the thread). You can also just use a strong oxidizer and a bit of heat. I think I remember some mixture of iron(for catalyzing it, I think) plus hydrogen peroxide in warm water will break down a lot of organics too.
Also, I see. I thought by waste you meant the more biological kind and not e-waste and metal scraps. There are actually microbes that do "digest" metal, kind of. They use them like we might oxygen, but usually they use the rusty forms(various metal ions in solution to be more specific). The blood falls in Antarctica is full of said bacteria actually, it's what makes it so bloody looking, all of that rust :). https://en.wikipedia.org/wiki/Blood_Falls
Also I imagine you could get it done internationally without much issues. There is also another way to make diamonds beyond the hot, compressed way but the other way makes tiny diamonds instead. https://en.wikipedia.org/wiki/Verneuil_method
You'd need to recapture the carbon though since most of it won't form a diamond on the first pass. It can still make quite large gemstones too, but it's a lot of work.
