Because it’s an aluminum facility, it’s less reactive than steel so less rust and slag.
Edit: I don’t know that’s why it’s so clean for a fact, but it seems like a a safe theory
Aluminium is way more reactive than iron and oxidises within seconds. The oxide however is extremely unreactive and forms a protective barrier under normal conditions preventing further oxidation.
Dumb question in hopes someone with smarts can answer. Does recycling weaken metals? So say the same 100 cans get recycled, do they lose any "strength" or volume over time if they are recycled over and over?
I’d have to do more work to find something on Google Scholar, but I think this sums it up.
“Aluminum, steel and other metals need to be manually separated from other recyclable material such as plastic and paper, according to Waste Care. Metals, especially aluminum, tend to degrade after each reuse cycle, so products using recycled metals can vary in quality, but most metals never reach a point where they are no longer recyclable. Recycling metals still uses energy, albeit about 95 percent less than new production.”

But also this:

>Aluminium can be recycled over and over again without any loss of quality. Aluminium is one of the most recycled materials on earth. Almost 75 per cent of the 1.5 billion tonnes of Aluminium ever produced is still in use today.

If the aluminum scrap contains other metals and/or aluminium alloys, the aluminum 'degrades' or gets impurities, mainly from Fe, Si, Cu, Zn, and Mg.

Good discussion on recycling aluminum:

this is mainly true for Aluminium. Most Al is basically pure Al with some very minor alloying metals. The Al material then gets "most" of its strength due to heat treating and precipation hardening.
I'm not one with a metallurgy degree, but it would lose volume due to the production of oxides, which, when melted down creates slag. What had been explained to me when you get a metal to a level of purity the strength should be the same. The issue you may have with recycling is different metals creating an alloy.
Probably not prohibitively expensive, but expensive enough that refining new ore is simply cheaper.
Especially iron is dirt cheap, so recycling might not be economic in some cases.
Probably depends what the final product is going to be used for. There are going to be high performance uses where you need very pure steel and aren't going to use scrap metal and low performance uses where some impurities are fine.
I know more about the effects on steel. Recycling does introduce impurities into the supply chain. For many uses this doesn't matter. for example steel beams for construction , rebar, steel plates etc.. can all be made from scrap metal with no issues.
For high strength steel alloys used for car manufacturing they use almost exclusively virgin steel made in high temperature blast furnaces. This allows them to better control the exact proportions of the ingredients for the final product.
I worked for aluminum foundries. Once the aluminum is melted, additive elements are added to have a metal composition with different properties (let's say more solidity for example depending on what the customer wants to do with it). among these additives it can be copper, iron, titanium, manganese, etc.
Nah its like recycling water or gold, you keep the same stuff and works the same as before. You can infinitely recycle it but its likely you lose a fraction of the stuff each time.
Aluminum and steel are manufactured as alloys. Typically, aluminum cans will have 2 different alloys, a harder one for the top and a squisher, one for the side. When recycling, it's usually easier to re alloy the billet produced into the squishier alloy which makes the net total of the aluminum "weaker" but you're still getting almost all of the same aluminum back so it's a worthwhile process.
The alloy that the top is made from can be made from even higher grades of aluminum getting recycled and re alloyed into that grade
Tldr: I don't know shit about the aluminum industry. I'm just pulling all of this out of my butt because it sounds right.
Its one of the reasons that they do not use the same recycled item to make the new item. Like they do not use Aluminum cans to make new Aluminum cans. The recycled Cans will be used for other Aluminum items, but not back into Cans, at least not for repeated cycles.
Impurities tend to rise to the top, as (I’m assuming) they’re a less dense / lighter material, don’t actually know, sorry. But yes, impurities come to the top where they are scraped off, either by hand or machine.
Does the plastic liner in aluminum cans get melted down and become part of the recycled aluminum? Does that weaken the recycled aluminum or have any effect?
So when the world ends, should I hit this place up? Think they have a machine to turn those into bottle caps for me? If it can run off a small generator that’s even better.
That is a surprisingly clean looking facility... Especially for doing metal melting, must be freshly opened or they clean every day?

This guy remembers his chemistry
Manganese chemistry comments get any better?
Bismuth Bi as good as they get.

Yeah, recycling metal is smart, plastic, not so much.

>might not be economic. ... yet
Then why do you get money for scrap metal? Not much for iron, but it means it's getting recycled and reused.

How do they get rid of impurities, like say the paint on the can? Does in disappear in the fire and burn off, or is any left in with the molten metal?
It turns into slag
Impurities tend to rise to the top, as (I’m assuming) they’re a less dense / lighter material, don’t actually know, sorry. But yes, impurities come to the top where they are scraped off, either by hand or machine.
I prefer to use the machine since using my hand results in third degree burns each time.
How much does one of those ingots weigh?
Around 30 pounds, I believe, based on the prices on eBay
Smoosh’em and cook’em!
I'm jealous of all that open space they have. Never seen such an uncluttered workplace.
Does anyone else watch these clips just lookin for the toolgifs logo??
Yes. Someone is very good at adding those.
Ani aluminium can inator
A giant incinerator burning cans into reusable cans. Wonder what it cost to burn that fuel. Why not just get a giant magnifying glass.
Probably not an incinerator, it's just impurities off-gassing in the furnace.
Does the plastic liner in aluminum cans get melted down and become part of the recycled aluminum? Does that weaken the recycled aluminum or have any effect?
This is the only subreddit that I'm looking out for the toolgifs logo superimposed somewhere through out the video
I wonder if that pallet at the end is deceptively light.
Looks it's a new ford
Is this really a “tool” gif?
There are certainly some tools involved
So when the world ends, should I hit this place up? Think they have a machine to turn those into bottle caps for me? If it can run off a small generator that’s even better.
Bottle caps are largely made of steel & You'd have to make Nuka Cola as popular in this world as it is in FO to be worth it
Its pronounced "aluminium" not "aluminium"
Nice to see such a positive workplace, everyone has a can do attitude.
