Signapore: Researchers at the Nanyang Technological University in Singapore (NTU Singapore) have successfully used bacteria to combine two abundant waste streams into clinker-free biocement. NDTV news has reported that the scientists developed the material from by combining calcium ions with urea in a mixture of industrial carbide sludge and urine. The process takes place at room temperature, reducing CO2 emissions while also offering waste management benefits.
The NTU Singapore team is presently testing the biocement on artificial beaches. It will subsequently investigate other possible large-scale applications around Singapore.
