At the CMT tourism fair in Stuttgart from January 17 to 25, 2026, researchers are collecting urine from motorhome owners for a scientific project. The University of Stuttgart uses it as a raw material to produce bio-concrete, a potentially CO2-neutral building material. Producing one cubic meter of this concrete requires about 26,000 liters of urine.
