I assume that if we have got far enough to talk about it, that it can stand up to wear and tear the way concrete can. It is still the kind of product that only a city can like and use with careful attention to costs.
Consuming plastic waste is a problem that is best solved in the city before it ends up in landfills and the ocean. This is at least what appears to be a good stab at the problem and let us hope it stands up.
I think that the consumer would also pay a premium price for this because it will keep underlying soils under patios healthy. Many yards are concrete zones suppressing border plantings.
Of course, it may encourage roots to demolish such establishments.
'Plastisoil' could mean cleaner rivers and less plastic waste

A new cement-like material that could be used to form sidewalks, bike and jogging paths, driveways and parking lots, may be able to lessen two environmental problems, namely plastic waste and polluted rainwater runoff. The substance is called Plastisoil, and it was developed by Naji Khoury, an assistant professor of civil and environmental engineering at Temple University in Philadelphia
With traditional concrete and asphalt paving, rainwater stays on the surface and runs into the storm sewers, accumulating oil and other road filth along the way. With pervious surfaces such as Plastisoil, that water is able to go down through them, and into the soil below. This certainly reduces the amount of pollutants entering the rivers, although Khoury and his team at Temple are currently trying to determine if Plastisoil could even serve as a filter, that removed pollutants as the water filtered through.
Khoury said that it uses less energy to produce one ton of Plastisoil than one ton of cement or asphalt, and that it’s less expensive to manufacture than similar products. It takes 30,000 PET bottles to make one ton of the material, although he is hoping to be able to use other types of plastic in the future.
