Have you ever thought about building a house with pee and sand bricks?

Sustainable houses and cities, as many say, are the future of an ecologically sound world. There are many alternatives to finding ways to live more environmentally friendly - simple acts such as sorting out the garbage already make a big difference. However, if you really want to join the greener world project, you might be interested in Peter Trimble's proposal.

Odd and, disgustingly, as it may sound, Peter Trimble collected daily doses of his own pee to mix with certain amounts of sand and other bacteria, developing bricks. The material of the bricks is certainly strange, but Peter guarantees that they are very sturdy and firm. The process of creating the material is entirely possible and is a demonstration of what bacteria are capable of doing with their metabolism.

On Peter Trimble's website, you can watch a video where he collects amounts of sand on the beach and places it in the small “brick machine”, along with other substances and the pee. Can this combination be a green solution to avoid using concrete?

When bacteria do the job

The so-called biotijolos are not exactly new, since in 2010 Professor Ginger Krieg Dosier began to experiment to take advantage of the bacteria. His chosen microbes were able to metabolize a mixture of sand, urea and calcium chloride. The result? A type of glue that strongly binds sand molecules together. Since then, the professor has set up a company called BioMason to produce sustainable bricks. The company's slogan is "we develop our materials by hiring microorganisms".

In Peter Trimble's case, the ingredient is his own, his daily pee capable of uniting all the substances and the doses of sand into the bricks. Unlike normal brick production out there, this more “home-made” style of production is quite sustainable, as no polluting gases are emitted - and much less waste of material.

To get an idea, it is estimated that 96% of the materials used in brick production are wasted; Only 4% of the total is transformed into brick. However, there is also a disadvantage for biotijolos: the same metabolism can turn urea into ammonia, which can contaminate groundwater (if present in the region).

However, with good planning there are ways that can prevent possible contamination. In any case, it is interesting to note that there is already a method capable of making bricks from a truly natural environment.
