Individual,
Are you sure you want me to answer that?
Or would you, like many on this board, prefer to only hear from people who think you're right, and ignore potential problems (even when they're very likely to occur)?

If you really are after the truth, don't just take my word for it; look up rare earths yourself - you'll see I'm right!

And of course I'm not against trying to solve the medical waste problem. But the easiest way to solve it is with high temperature incineration. And as I said in my original post here, disposal in volcanoes isn't as easy as it sounds. The technical challenges aren't insurmountable, but they're enough to make it unlikely to be the cheap option you blindly assume it to be.

Perhaps someone can tell me what they are actually frightened of? Do things like Covid have superhuman capacity? It sounds like you are trying to get people believe germs and viruses have supernatural powers. Just because some addled, greedy, idiot public service buffoon says 1100 degrees Celsius means nothing but huge extra expense and corruption. Where is the organism that can stand 100 degrees? This is the usual PS response to serious but easily fixed problems. I think it is a great idea but that the delivery will be far harder than first appearance. Still it is always good to explore.

Aidan,
The rare earth part was meant light-heartedy. My point was that in the distant future our present waste could possibly become a useful if not valuable resource.

Been to the island of Hawaii and seen the volcano Mt. Kilauea. Its a large island, the largest in the Hawaiian group. The population is not huge about 200k, and the island is more than half the total area of Hawaii. How people live on such a place is beyond me. Covered with black lava flows, which resemble giant car parks. There is a general lack of water, people take their tank on wheels to get water from government bores. Besides tourism, cattle ranching is the big industry. The volcano dominates the island, and all aspects of life are tied to it. It shows how powerful nature can be and the efforts of man to "control" nature are puny in comparison to natures strength.

Look what happened a few weeks back when that Spanish bloke missed the Tuesday night wheelie bin pick up on the Canary Island of La Palma and decided to dump his rubbish in the Cumbre Vieja volcano. All was quiet until he threw in that last bag of smelly enchiladas. Now look at the place. Me thinks we better not throw our rubbish in volcanos.

Is it perhaps possible that if volcanoes are kept 'open' they'll less likely 'explode' ? I mean if there's not pressure build-up to throw magma all over the villages ?
If Paul1405's mate hadn't thrown enchiladas which are bio-degradable, into the volcano but had thrown un-biodegradable old engine oil into it things might have turned out better. Bad things always happen when silly people prevent thinkers from doing good things !
There'll always be waste no matter what. It's the kind of waste we must focus on.
Toxic un-biodegradable is the problem not biodegradable. Then there's other waste, waste of space Left indoctrinated, waste of time Lefties, waste of resources greed mongers etc.
A one-way snorkelling trip to Magma Lake would solve those too !

Hi Indy,

I believe man has made some little use of volcanic action, with the generation of electricity and the use of hot springs. The Maori used hot springs to cook kai (food) for hundreds of years. Been to Rotorua NZ, sometimes referred to as Rottenrua, due to the sulphur smell when the wind blows in the wrong direction. I though it was a bit disconcerting to have steam vents in your backyard, but the people there seemed to accept it as normal.
