Nairobi has a particularly acute problem of plastic trash everywhere which this really scratches the itch of helping solve this in an economically incentivizing way. I'm sure there are likely other places where the problem is prevalent. I'd certainly buy these if they were available and competitive with concrete paving stones in the U.S. There are some use cases where I think they would be preferable as they would be less likely to crack than concrete.
