Plastic bricks that are as hard as concrete
@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
@barefootstache Oh, that might work out then. Though chances of microplastics (due to wear and tear of walking/riding over it) will be bigger in that local area then. So, that's still air pollution increase. But eh, if there's no other way...
@trinsec Microplastics is a whole different issue and I doubt it would make any difference if it is created via the streets or via landfills. Ideally no plastics should have ever been created or at least any that disturb our bodily functions. Though that is a whole different topic.
@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.
