Oh no. For some reason I thought we were manufacturing the sand used in construction and stuff. At what point do we stop stealing it and start making it? Is that actually any better?
Yes, sand in the desert and beaches is "too old", in other words, it's too smooth and can't hold material together. That's why Dubai is importing huge amounts of sand while being literally a city in the desert.
On a more serious note, they can find cement from smashed buildings. Destroying old rundown hotels to develop something else. Cool, some one wanna buy those debris and put them to some good use.
