Building with stone can replace steel and concrete. Gabbro and Basalt stones are ideal for both, building and ERW. The stone dust is generated by the process to cut stone blocks into slabs, which are used to replace steel and concrete. This means in effect, that replacement of steel and reinforced concrete generates a business model for scaling ERW to gigatons: a win-win-win solution. The main winner for the first time is the climate, second winner is a new business model eliminating CO2 generation through buildings and third winner is people with enough homes and healthy food. The first Gabbro stone was utilized as a business model in Italy in the middle ages for making mill stones for finest quality flour of best pasta and bread making throughout Europe. The stone was found in a small town called “Gabbro” in Tuskany/Italy. Gabbro rock powder is utmost well suitable for ERW. Gabbro can be found anywhere else, too, mainly in the global south, also in Europe, China, USA and Australia.
