"Australia has that problem too & no volcanoes !"

I understand Professor Nincompoop who was recently appointed head of Modern Australian Development, MAD for short, has made that very problem his life's work. Pr. Nincompoop suggests that we buy several 100 megaton unused atomic bombs from a large unnamed friendly alley located somewhere between the Pacific and Atlantic Oceans. Pr. Nincompoop has calculated the location for Australia's first man made volcano should be a safe distance from the national capital, Canberra, located about 10km from the city centre would be ideal. According to Pr. Nincompoop the resultant blast from the detonation of these several A-bombs will only be slightly larger that the explosion of the island of Krakatoa in 1883, and will result in our very own man made volcano twice the size of Mt. Vesuvius.

Indy, you thought you were going to miss out, no you're not. The army of old folk from the Seniors National Service will be tasked with transporting all that unwanted rubbish up Mount Nincompoop (named in honour of the good professor) for disposal. With backpacks loaded with spent plutonium and a cut lunch our hardy oldies will joyfully undertake on our behalf the disposal of all that nasty stuff up there in Mount Nincompoop. Problem solved!

The very people who demand medical care at a moment's notice should be made to spend a week working at the medical waste disposal section of a hospital. They'd voluntarily jump into that hole at Mt Nincompoop rather than do the work.

OK. If there is a similar problem in Australia - although I have to admit that I've not heard of it, apart from nuclear medicine waste which we seem to be dealing with - let's concentrate on that, and let foreigners do their own thing. I have to say though, that all these "problems" cropping up could be just part of the usual suspects scaremongering to control people all the time. Covid, climate change, are starting to lose their grip, so something else has to be thought up. For me, the China threat is what we should be concentrating on.

Of course, if Australia can be made to see that we are the ideal place to store all sorts of waste, and make money out of doing so, we could be taking the problems off geological unstable countries like Indonesia and overpopulated Europe.

Individual,
To properly destroy medical waste it should be heated to 1100°C.
Doing so in volcanoes isn't as easy as it sounds. I'm not saying it can't be done, but thermal conductivity is not always as high as you might assume, and lava can cool down pretty quickly

To properly destroy medical waste it should be heated to 1100°C.
Aidan,
Yes, I read that but when one considers that it won't get taken out of the volcano again, surely it'll disintegrate with ongoing boiling 24/7.
I mean isn't the maintaining of such temperature that is the technical & environmental difficulty ?
In a volcano that goes without having to do anything apart from throwing it it. Of course we shouldn't throw thousands of tonnes of waste into a little 3 metre diameter volcano but some of the larger live ones should really be tested to do the job. At least try to do with highly contaminated waste & see how it goes. Sharps etc would very quickly melt & mix with the molten rock, better than burying them !

individual,
Why do you assume it won't get taken out of the volcano again? The lava moves to where it cools.
