Modern science has offered people many new concepts and interesting technologies, especially in the field of environmentally friendly construction. And today, a talented team of specialists from Cape Town University has presented its new development, which consists in the technology of creating full-fledged building blocks from human urine. It sounds extremely strange and therefore interesting, but if you look at the issue more precisely, it will become clear that urine plays a decisive role here, however, some other chemical compounds and chemical agents that form the process also participate in the process.
As an example of inspiration, experts drew attention to how the process of formation of a solid residual urine breed of mollusks and arthropod-crustaceans occurs – this process is called carbonate precipitation. Granules of sand in urine are colonized by bacteria that produce an enzyme called uriaz – being compatible with urine, it breaks down into hard rock called urine and this is the chemical reaction necessary to produce building blocks.
It is worth noting that the incomparable advantage of this approach is the fact that the structure of the blocks contains a high proportion of calcium carbonate and it is much cheaper to produce such blocks – in addition, the structure of the residual rock is flexible enough to give it a wide variety of forms and formats. An equally interesting advantage of this technology is the ability to create blocks at room temperature, thus avoiding the need to reach high temperatures.
All this together allows you to create really high-quality and solid building blocks, which are practically not inferior in strength to traditional stone or concrete blocks – with the only difference being that the degrees of hardness and flexibility can be adjusted even at the stage of the block forming process. Thus, the new technology of specialists from Cape Town may soon become one of the most promising in the field of environmental construction.
