Scientists Convert Industrial Carbide Sludge and Urea From Mammalian Urine Into Environment-Friendly Cement
Scientists at Nanyang Technological University in Singapore (NTU Singapore) have discovered a way to make biocement from trash, making it a greener and more sustainable alternative to ordinary cement. Biocement is a type of renewable cement that binds soil into a solid block by using bacteria to induce a hardening reaction. Biocement has now been made by NTU scientists using two common waste materials — industrial carbide sludge and urea (from mammalian urine). They invented a method for creating a hard solid, or…
