Not so great. Plastic is going to be seen like asbestos in 50 years.
Let’s have a little optimism eh guys? This is not even a problem as far as anyone can tell, and even if it were it would be solvable.
This is brilliant. It's like asphalt, which is just concrete (cement, sand and lime) with some of the cement replaced with oil/tar. This is that same idea but using plastic not oil/tar. Truly brilliant. It's a new type of composite building material.
The bricks will aspirate toxic chemicals when exposed to direct sunlight: "...Plastics leached twice as much pollution in sunlight as in darkness, they found. One bag leached 263 different chemicals in the dark but more than 13,000 when exposed to light! Others leached even more. And the longer bags were exposed to sunlight, the more chemicals they leached. ..." https://www.sciencenewsforstudents.org/article/everyday…
Note that "twice as much" doesn't mean it's a lot. Nor does the number of chemicals indicate danger.
This is a great way to get microplastic through abrasion into even more places within the foodchain. Wonder if it burns nicely too, plastic after all is "frozen gasoline" - here mixed with sand. /debbiedowner

As far as I know, asphalt concrete doesn't contain any portland cement, at least usually. It's just gravel, sand, and bitumen/asphalt/tar.

plastic can be infused with chemicals to not burn, but other than that youre right.
Do people of color ever roll their eyes at websites like this? Does it ever just seem silly? edit: I am white, and my question is not for white people. I call it “peopleofcoloronhackernews” :^)
It's nice to see positive stories being highlighted.

What I don’t like is when the claims are needlessly exaggerated.
When the concrete weathers, will the plastic in the bricks turn into micro-plastic?
It will break down much more slowly as a solid object than as separate pieces of plastic. It will likely be painted or covered with a facing anyway.
Plus if you ever want to modify the building you’ve got an environmental hazard on your hands.

Asphalt also emits microparticles during wear and tear, as do tires... It needs to be tested, not assumed.

Right on cue the microplastic doom cult shows up whenever the word plastic appears. Let’s have a little optimism eh guys? This is not even a problem as far as anyone can tell, and even if it were it would be solvable.
