Porsche started galvanizing their bodies in the 1970s, VW started in the 1980s, Japan only started galvanizing their bodies in export markets, in response to the germans, and only recently (last 15 years) have been galvanizing all their bodies domestic and import.
Toyotas cost nothing compared to Porches, so 1-0 Japan vs rest of the world.

Well perhaps "retain" should be added. Making something last longer isn't quite "reduce" or "reuse".
Isn't this like corrosion engineers validating their own industry? I mean it's a fair talking point but also like asking VCs how good their returns are?
Reminds me of the perennial reports from the American Society of Civil Engineers talking about how the US's infrastructure is degraded and everyone had better hire a lot of civil engineers to fix it.
I’ve spent years working on a VW bus restoration, and this is something I’ve thought about so much. Once you’ve had to clean up rust you begin to see it everywhere. It’s like having a disease. Anyways, yeah it would be fantastic if metal just didn’t corrode. That would be one of the greatest gifts to the world.
My dream is one for stainless steel. Come up with either a different alloy or an improved process to make corrosion-proof metal from abundant iron. I can't imagine the leap forward if a chunk of stainless cost nearly the same as mild steel. (And didn't have weird failure modes, etc.)
This is an important issue. People keep talking about recycling, but much more important than recycling is just being able to use a thing for longer before you are even thinking about recycling it. Japanese automakers did the world a great favor when in the 80s and 90s they made much longer lasting cars and made longevity and resale value an important consideration in the purchasing decision. They did this mostly by…

I imagine a substantial part of this is the rusting of rebar in concrete structures. The problem of rebar has fascinated me, and one German company has begin making carbon fiber reinforced concrete instead of steel, with amazing results. You can reduce environmental waste by having structures last longer and you use less concrete. I'm looking forward to this becoming more ubiquitous. https://www.aboutcivil.org/carbon…

Famously, 1990's Mitsubishi and Subaru vehicles can basically rust down to the frame before the drivetrain stops functioning. And they don't wait long to start on the former.

Why aren't bridges and ships made out of stainless steel? Is it too expensive, or not as strong as regular steel?
When choosing a metal material, it's important to consider not just its innate properties, but it properties during join. Welding can melt the metal surrounding the weld, which can undo many heat treatment or mechanical processes previously used to get the material to the desired specs.
This is why I get scared when I see articles about people developing plastic eating bacteria. Sure it is great for reducing waste but it’s a dangerous game to be playing for sure.
No, plastic was the mistake. That was the dangerous game, those plastic eating bacteria are one way to restore some of the natural order and hopefully at some point they'd run out of food.
Plastic is indispensable just like electricity.
