If you use approximately the same amount of material as in an aluminum can, you’re already at 3x the weight of an aluminum can. Stainless is also far less malleable and much more brittle than aluminum, so the minimum wall thickness is much higher for steel. Aluminum can walls are 0.11m thick, whereas the minimum wall thickness for stainless steel alloys is around 0.50mm thick. Meaning you’d need around 4.5 times as much material, making the stainless steel can weigh at least 10 times as much as the average 15 gram aluminum can. A 12-pack of soda would weigh 4.5 pounds more. Now imagine how much transporting that extra weight costs.

Stainless steel is great for reusable stuff, but it’d be impractical at the same scale as aluminum cans.

Yes, it is actually. You melt the aluminum and skim off any remaining plastic and contaminants from the top of the molten aluminum. It’s a standard, millenniums old process for any metal working.

Problem is the stainless steel you’d need to use in order to get the corrosion resistance and non-reactivity with the contents is prohibitively expensive. Cheap stainless steel alloys offer pretty poor corrosion resistance - see the CyberTruck rusting after being rained on a few times.

Easy solution: only buy drinks in aluminum cans or glass bottles. World is already drowning in microplastic pollution.

I bet you’re fun at parties.

Where is this at? I’ve never seen 440ml or 440ml cans in North America. Canned drinks/beers usually come in 355ml (12 US ounces), 473ml (16oz), 500ml (16.9 oz), or 19.2 US ounces (20 British ounces aka British pint). Other less common sizes are 8oz (236ml / Red Bull) and big beer formats like 24oz and 32oz (just shy of a litre).

404ml is around 13.66 US ounces or 14.2 imperial ounces. 440ml is around 14.7 US ounces or 15.5 imperial ounces.

Usually when you get a measurement that’s not a nice round number like 500 or 750 it means it was probably converted from some other measurement standard. But both measurements seem completely arbitrary for what I assume is an English speaking country.

I looked through some antique measurements but didn’t find anything useful. It seems to be more than half a chungah, but far less than a butt.

I wrote an anology up and hated it, so I discarded it. Glad someone else nailed it.

I love that you name-drop the US when it was the English, Spanish, Dutch, and French that raped every continent and genocided entire cultures before the idea of the United States even existed.
