@barefootstache I wonder how durable they are. I mean, any plastic I know will become brittle when exposed to the elements for too long. I doubt they're going to last for centuries like stone does.
@trinsec compared to stone probably true, though compared to concrete is the actual question.
Since I don't know what the situation is where they are implementing thus practice, I assuming they are being over flooded with plastic waste, thus repurposing the already given resources over importing concrete might be a good solution for them.
In countries/areas where there are dedicated recycling programs, I doubt this would make sense.
@barefootstache Well, considering that concrete already existed far before the Roman times (but the Romans were the first one to use it a lot), and many of those buildings are still up.. I have the suspicion that concrete might be more durable.
But if they use the plastic based bricks for temporary buildings (as in.. max 10 years probably?) it might be indeed useful.
But knowing us humans, and always postponing maintenance and rebuildings.. I foresee accidents within a few decades. :P
@trinsec the video suggests that they are using it for the streets. I don't know what that includes, though am assuming just sidewalks and curbs.
