I prefer the method of dumping it on maralago property and anything else trump owns.

Make his stuff look like the dump he's creating throughout all of america

I always like the semi-sci fi idea of the universal recycler. It's a method of recycling that relies entirely on known science and technology, but is simply impractical in the current economy.

The idea is that you literally turn everything into a plasma and then separate it down into base elements via magnetic separation. On one end, you input nearly anything - regular trash, construction waste, "recyclables," medical waste, decommissioned biological weapons - it doesn't matter. It all gets torn down to base elements and sold back into the economy. The only waste this method couldn't deal with would be nuclear waste, as magnetic separation isn't going to magically make unstable nuclei stable again.

This would totally work in principle. It's just incredibly energy-intensive. You need an economy where either the cost of energy is much much lower, or people are willing to spend much more in order to dispose of waste. It would enable the complete recycling of nearly anything, but it would just require an ungodly amount of energy.

This is essentially plasma gasification with an extra step at the end to sort the end product. Plasma gasification has been done commercially for decades (although it is still very niche). Some facilities are actually net energy producers. The main economic challenge at this point is really just the capital investment.

The separation on the backend would not be easy. But I suppose it is quite similar to that. This has the benefit that it doesn't emit anything or generate any waste on at all. It literally processes everything back into its pure base elements. It is a true universal recycler. It's something that could really help make that utopian vision of a true circular economy possible.

[–] [email protected] 1 points 1 day ago

I'm not sure it would truly be waste free though if it separates everything into its base elements.

Things like wood are useful because they are made of molecules that end up as a useful material. Its base elements are much less useful.

You could use the hydrogen and oxygen but you would probably end up with a lot of extra carbon that no one on the market would need and then have to dispose of it somehow.

That's a really cool concept that I hadn't really considered being an option before. As you said,.that's definitely going to take a lot of energy to accomplish so maybe it'll be an economic possibility after fusion is readily available, which sadly is still a ways away but getting closer to becoming achievable every day.

A Star Trek Replicator in every house, please. Throw in the trash, get out whatever we need.

[–] [email protected] 5 points 2 days ago (2 children)

Yeah, this is basically a reverse replicator. We can't build the replicator, and we may never be able to. But we can however build a reverse replicator! Or, the unreplicator!

You know, that's what you could call it if "the universal recycler" is to pretentious. Just call it the unreplicator!

[–] HeyThisIsntTheYMCA 1 points 1 day ago

Sounds gooey

[–] [email protected] 1 points 1 day ago (1 children)

That is how Star Trek replicators worked. They went both ways. You say "catfish po' boy with extra chuckle", and it produces a sandwich on a plate. You eat the sandwich, and then place the dirty plate right back into the replicator to be recycled. The plate, along with any remaining food crumbs, sauce, etc. get converted back into energy, ready for the next thing you replicate.

[–] [email protected] 2 points 1 day ago

Sure. I just find it amusing that while we can't build a replicator, we can build a shitty unreplicator.

Would storing nuclear waste this way be a problem though? I'd basically be an extremely overkill version of the current best known method for storing the waste sealed in base rock for millennia or 20

[–] [email protected] 4 points 2 days ago

No. This is separating things down into their base elements. Yes, if you had some alloy that was half enriched uranium and half some other element, this machine would separate the alloy into those two elements. So you have one bin full of another metal like iron or tin. And then in the other....you have a pile of extremely radioactive uranium. Simply sorting things by atomic number does not make an isotope cease being radioactive. However, you could use this to aid in nuclear waste processing. It would be a lot easier to deal with waste if it is broken down into its constitutive elements. However, it's likely that if we ever built these, we would keep the ones used for anything radioactive kept for that and only that use. Highly radioactive material passing through any complex machine is going to cause all sorts of problems. So your local city recycler wouldn't be doing any nuclear materials recycling. That would be done at dedicated facilities.

Putting the littering in the littosphere as intended.

[–] [email protected] 1 points 1 day ago

or you store the trash somewhere until recycling is economically viable, which it probably will be, at least for some types of plastics, once that renewable energy gets significantly cheaper than the oil required to make new plastics.

[–] [email protected] 10 points 2 days ago (1 children)

At ~5 cm / year of continental drift, you're going to have to spread out the trash really really thinly.

[–] [email protected] 7 points 2 days ago (2 children)

I hear the earth is really really big.

dont spread misinformation under my poste please

I'm actually fine with dumping waste glass and cullet in the deep ocean. It's inert, non-biodrgradable, non-polluting, and it's made of the same stuff that's already there, silica.

I'd also be in favour of carbon sequestration by filling decomissioned sea containers with woodchips from tree trimmings, and sinking these in the deep ocean, below 6km. The cold and lack of light would prevent bacterial breakdown of the wood, and so it wouldn't rot and release it's carbon back to the atmosphere for thousands of years. The steel sea can would eventually break down into iron oxide. You could sequester 30 tons of carbon per sea can that way. One containership could dump a quarter million tons of carbon in one trip.

Would this be any more practical than launching it into the sun? Or less? It would take a ton of money and work to dig a big cavity out of the ocean floor. It's an honest question, I want to know which crazy idea is less crazy.

[–] [email protected] 6 points 2 days ago

It would actually be substantially easier to send things out of the solar system than to crash them into the sun.

[–] [email protected] 3 points 2 days ago

Launching things into the sun is actually really hard. You essentially have to slowdown the payload from the velocity of the Earth's orbit, all the way to zero. Otherwise it just becomes another thing orbiting the sun.

I tried looking it up, and I remembered I’m not smart enough to understand all of the techno-jargon. But what I did understand is that it would take a large rocket with a butt-tonne of fuel, and that right there makes me think it wouldn’t be worth it due to cost and environmental factors of burning so much fuel. And, there is a monumental amount of garbage.

[–] [email protected] 7 points 2 days ago

i think part of it would come back out as gas and through cracks ground water could get contaminated, but that's not much different from what happens at landfills RN

[–] [email protected] 4 points 2 days ago (2 children)

IMO one of the benefits of landfill is that it can be mined and recycled at a later date when we develop the tech to do so.

[–] psmgx 5 points 2 days ago (1 children)

"when" is a risky assumption

[–] [email protected] 1 points 2 days ago

we already do have tech that can refine out the valuable materials, it just happens to release toxic chemicals into the air and not be as cost effective as traditional mining yet (partially because we can do traditional mining in areas with looser workplace safety laws)

[–] [email protected] 1 points 2 days ago

Looks like a rage bait comment for that guy who wants to "mine" his Bitcoins from the local landfil which does not allow it.. 😄

[–] [email protected] 5 points 2 days ago (1 children)

Here is an even crazier idea. We fucking manage our trash and hold corporations accountable for waste. I'm sure pumping millions of pounds of trash into the earth in the name of limitless capital greed won't turn out bad. /S

[–] [email protected] 4 points 2 days ago (1 children)

You're right but there's no need to bring that cynicism to every post.

[–] [email protected] 1 points 1 day ago

Because what we have been doing in the past is working? How is trash island in the ocean doing?

[–] [email protected] 3 points 2 days ago

It would quite a slow process, but eventually it would vanish.

[–] [email protected] -2 points 2 days ago

This is just a landfill with extra steps
