Students in Africa have given the world a new and literal meaning to the expression, “liquid gold.” Technology has since evolved rapidly over the years, and everything in the modern age now seems far-fetched from when ancient civilizations figured out how to smelt bronze and other metals. In the present, humans have become well-versed in turning the most unimpressive materials into gold, and this couldn’t be far more true than what students in Africa have discovered.

Science is an unlimited source of new discoveries and inventions that can either be very helpful or just simply peculiar. And bricks made from urine seem to take the cake in both attributes.
Discovered by a handful of brilliant students in Africa, the brick is made from synthetic or synthesized urine. It is mostly composed of urea, a colorless crystal-like chemical in urine, which is a breakdown of protein in mammals. In its first test, the bricks were compounded from synthesized urine gathered in large quantities. And in later tests, instead of the synthesized urine, organic human urine was used, and it proved to be successful.
This new method of creating bricks is called, “Microbial-Induced Carbonate Precipitation.” In basic procedures, lose sands are gathered and colonized with a special bacteria, which produce the urease enzyme. These enzymes break down the crystalline urea and produce calcium carbonate through a chemical reaction. This calcium carbonate is a rocky substance that is compounded and formed into a brick in any shape.
The use of such a natural and commonly-ignored material for the composition of objects such as bricks only reinforces that fact the science never fails to amaze and surprise mankind. The discovery of the urine alternative for bricks strongly sheds light on the fact that the modern age is getting closer and closer to finding environmental-friendly alternatives to several aspects of work and industry.
One can even, in awe, remark that our urinary wastes are excreted and flushed down in large quantities every day, in every home, in every city, of every country in the world. Retrieving them to be used in scientific and industrial ways has proven to be a ground-breaking idea in potentially reducing the wastes the world produces each day, and in a wide, dramatic degree.
The researchers behind the bricks made from synthesized urine have remarked that one of the few disadvantages of this new method of making bricks is that it requires an enormous amount of urine to be compounded. According to them, a single brick requires about twenty liters of urine at least. A healthy man with normal water intake could produce an average of two liters of urine per day. This means that in order to make a functional quantity of bricks, urine has to be gathered in large quantities in order to achieve a practical production. Additionally, the bricks have an average composition time of eight days, adding inefficiency to its list of disadvantages.
However, one cannot deny the value of this discovery when it comes to producing environmental and earth-friendly alternatives to construction materials. In fact, the major disadvantages of this new method of creating bricks seem to be light, and if these bricks find their way into factories for industrial production, the cons can be made inconsequential. In the future, they may even totally replace clay bricks as standard construction materials.
