Revolution under construction: Bio -petone from urine could change the industry!

Stuttgart, Deutschland - Researchers of the University of Stuttgart have developed an innovative building material that appears unusual at first glance: Biobeton. This new substance could revolutionize the construction industry by not only has high pressure strength, but is also environmentally friendly and has the potential to replace traditional sandstone and cement -based concrete. It is particularly noteworthy that biobetone can potentially be produced from waste materials, which significantly reduces the ecological footprint of the construction.

The production of biobetone is carried out by a procedure called biomineralization. Human urine is used as a raw material. In an elaborate process, sand are mixed with a powder -containing powder and rinsed with calcium -enriched urine over a period of three days. During this process, the bacteria dismantle urea and form calcium carbonate crystals that solidify the sand mixture and thus create a solid building material that has chemical similarities with natural limestone stone.

material properties and state of research

The previous results of the research are promising: the first rehearsals of the biobetone show a compressive strength of over 50 megapascal when technically stabilized urea is used. With synthetically stabilized urine, the pressure strength was 20 megapascal, while real human urine had a pressure resistance of five megapascal. These differences can be explained by the fact that the bacteria cannot remain active in full biomineralization time. However, the researchers strive to increase the pressure strength to 30 to 40 megapascal in order to make the building material suitable for masonry of two to three-storey buildings.

Currently, frost-speed experiments are also carried out to test whether biobetone is also suitable for outdoor use. The project was financed by the Baden-Württemberg Ministry of Science, Research and Art and shows the potential of innovative building materials in the sustainable construction.

sustainability in the construction industry

The development of biobetone is not just an isolated progress. The construction industry is located in a comprehensive transformation process in which regenerative building materials play a central role. According to Techzeitgeist , the industry actors are under pressure to lower their CO₂ emissions, since the building sector causes about 38 % of global CO₂ emissions. Regenerative building materials based on bio-based, recycled or CO₂-neutral materials are not only more durable, but also more environmentally friendly than traditional materials.

These new materials can be divided into different categories: bioba -based materials, recycled CO₂ for building material production and intelligent materials. For example, bio -based bricks consist of natural materials such as clay and plant fibers, which represent an environmentally friendly alternative to conventional bricks. Companies and start-ups use innovative manufacturing processes to develop these materials, with some already being used in pilot projects.

However, the challenges should not be underestimated. High production costs and compliance with legal building regulations represent hurdles that must be overcome. Industry experts nevertheless expect regenerative building materials to celebrate their market breakthrough in the next five to ten years. By 2030, sustainable building materials could then possibly become the standard in new buildings, especially in ecological projects.
