Project description

Imagine an affordable building material that shines like porcelain, has a positive impact on your health and safes maritime ecosystems.
When drinking water is produced by desalination, a highly concentrated salt brine is produced as a waste product. Until now, being dumped back into the sea, Salt has dramatic consequences for the environment. Bau.Salz demonstrates the potential of an unused resource: an environmentally harmful waste product is transformed into a high-quality building brick.
Not only the utilization of salt itself has a good impact on our environment, but every processing step from the raw material to the final product follows the principle of sustainability and considers the whole buildings life cycle.
By means of a smart, elaborated design the masonry blocks interlock with each other. This enables an omission of cement mortar and creates seamless, translucent bonds. The result is a brick that can barry just as much as the conventional ones- but without being burned or the use of emmision-intensive materials.
Despite its good impact on the health and climatic properties, Salt still is an underestimated material in the construction industry. Bau.Salz changes that, to make a contribution to a more sustainable desalination process and by that means counteract the fact that 2.2 billion people do not have regular access to drinking water.
