For the people asking about micro plastics...
I'd wager a bet, that cleaning up the tons of plastic trash and converting them to this, is by leaps and bounds reducing micro plastics in the environment. It's probably not perfect, but far better than just letting the existing plastic degrade in the open.
I'd be a lot less worried about micro plastics and a lot more worried about how fire resistant they are.
And you'd lose that bet.
I don't think so. The surface area of let's say a plastic trash bag is massive compared to compressed brick like this. Scale this to probably hundreds of not thousands of bags it takes to make one brick and it's a huge difference. Yes it still sheds and degrades, but the surface area is exponentially lower.
To get there you need to process the plastic which releases some of the myriad additives in that plastic, which are toxic. You want to sequester this plastic not free it's components. If you want to help, reduce the amount we are making in the first place, because any sort of recycling makes pollution worse.
Yes in an ideal world we would ban plastic. We aren't there, but I think this is a good step with what we have in front of us.
I'm not gonna say its a bad idea because it can be workable, but bricks have pieces break off or erode or whatever. When its rock and mortar thats nbd, but plastic? Eesh. Yeah you can use them on the inside of buildings but even then if a building gets demolished in some which way (or catches on fire), thats a whole thing too.
Look up "The Station" fire, there was melting Styrofoam falling from the ceiling onto people. I imagine these bricks will do the same.
Plastic can burn, but plastic can also have fire retardants mixed in to keep it from burning. The fire retardants themselves are a different environmental concern, though.
The only perfect solution to plastic waste is to stop making so much damn plastic.
You might be right, and you might be wrong, but if an engineer developes something you might expect that some tought went into it.
To that end, engineers spent a lot of time with asbestos too
Sure, and also with wooden structures, or rock, or steel. And they spent time on desposal of the asbestos in a safe way too.
Before materials sciences asbestos was a wonder material.
It still is, it's just a deadly one
There was a big indoor pool area close to where i grew up. One day the concrete ceiling just fell down because they used a steel that was eaten up by the chlorine fumes over time. A bunch of people died being trapped under the massive concrete slab. These were also highly regarded engineers who designed and built that thing.
Hmmm. That sounds like it could be what happens to those cheap apartment blocks that fall down in Florida on the regular. Sea air, steel supports...
If it's the one in Switzerland I was referring to, it wasn't some cheap construction job. It was actually recently inspected, and one of the steel hangers was found broken. The inspector then just had it fixed and never bothered to inform anyone, they just assumed it had been broken from the start. They were convicted of negligent homicide as a result.
Ah, consequences. More countries need that.
So it wasn't an engineering fault but a lapse in inspection. Maintenance is required for all engineering. Always has been.
Typically, inspections like these are also done by engineers. If you work in a field like this, it is improtant to keep up to date with current developments. Like in this case, since it was built it was found that the alloy used wasn't that great when contacted by chlorine. So an engineer seeing a broken hanger (along with some brown spots on other hangers) should have at least reported it and not just assumed it had always been like that. They should also have reported the brown spots. Typing this I do realize this was in 1984, and you couldn't just go on the internet to check if brown spots meant anything. Then again, as one of my engineering mentors always said; "Assumption is the mother of all fuck-ups.".
that's bloody awful! Was this the one in Switzerland?
You forget, business majors are often the ones who pay to develop things and they don't always think about things or listen when engineers talk to them.
I'm an engineer, and I've never hade the people paying me not listen to me. Why wouldn't they, they paid for it? It is up to me to give valid information for making the choice.
When you work in product development, it happens ALLLLLLLLL the time. The FAFO is nice when it inevitably backfires on them but its still REALLY frustrating.
Lmfao
I might hope for it, but never expect it. Roy J. Plunkett, and how Nobel made the money for the prize are fairly good evidence in that regard.
You know what else makes good bricks for cheap? Clay. Clay and straw. You can even use mud. You can dry in the sun even.
At this point plastic is probably more available than clay. Especially if Kenya is one of those countries we send our "recycling" to, that usually just ends up in open pit third world landfills.
It depends on the area for sure, but mud works for bricks too in parts. Some of the ancient world was built with mud bricks, I think mesopatamia for instance, like babylon, was thought to be mostly mud bricks.
The plastic is toxic is the problem, full of toxic additives that get released in any sort of processing, the best case for used plastic is to put it somewhere out of rain and sun. It sucks, but the best thing to do is make less in the future. Unfortunately we are making exponentially more plastic all the time. It's really incredible how society really dropped the facade we had these last 30 years and showed itself to be, well, what you are looking at.
Cool concept.
I would love to know more. Mainly how energy demanding the process is, Does it start to brittle in the sun shine, how fire resistant it is. Does it shed more or less microplastics than recycling the plastics other ways. Can the bricks be recycled if necessary.
Plastics aren't being recycled, or reused, in other ways, that's the biggest problem after, you know, just making and using too damn much plastic--that's the "reduce" part we tend to ignore.
There has been massive progress in banning single use plastics and using alternative packaging materials.
You are missing the point here. If i had right now resources to build a single facility, would dedicating it to make these bricks be better or worse than making mechanical recycling center for plastics?
Kenyans gonna live in Lego houses.
I'd actually love to live in a Lego house. Colorful, change on demand, weekend fun with the kids.
lego lawsuit incoming in 3... 2... 1....
Honestly a shit idea
This is going to make the microplastic in testicles problem so much worse isn't it
I have said for years, as soon as it becomes more profitable and important for climate science to be supported it will get figured out. Hopefully before it's too late, but probably not.
That's great, but not a long-term solution. Only intermediate storage of toxic waste that will still turn partly to CO² with tens of years.
Im sorta curious about it being used as a spacer to use less concrete.
Now that brings me joy
why aren't these used in construction elsewhere if it's five times stronger than concrete?
