Very interesting, because cement is more unsustainable than many know. Just think it is all over in "western" societies and beyond. 5 % of co2 emmissions come from cement plants , GLOBALLY.-more than the entire aviation industry. Thx David.
Its great to see some solutions to this unsustainability and the UNity worldwide to fix it. WE NEED cooperation , not competition to get thru this.

It does not really say , what it is made of, I hope it is not toxic to us or the environment. Lets not make any more unintentional sustainability mistakes , that take away from us what we seek to give. No more Greenwashing for a buck.
