Scientists turn urine into building bricks 2018.11.28
20035 20035

RESEARCHERS from a South African (南非) university have successfully turned human urine into bricks. This means pee is no longer just waste; it can become construction material for eco-friendly office buildings and houses.
This invention was created by a lecturer, Dyllon Randall, and his two students at the University of Cape Town (開普敦大學). After receiving a government grant in 2017, they began researching, at first using urea, then human pee.
Through microbial carbonate precipitation (微生物碳酸鹽沉澱), they combined pee, sand and bacteria and ‘grew’ the bricks.
The team hopes these bio-bricks will one day replace concrete, which creates lots of carbon emissions to make.
