Isolation and identification of bacteria utilizing microbially induced calcite precipitation (MICP) for the recycling waste concrete fines
Original language description
During concrete production, large quantities of carbon are released into the environment. A promising route to a more sustainable construction industry involves the use of microbially induced calcite precipitation (MICP) in concrete recycling. Here, we investigated utilizing the ureolytic activity of the alkaliphilic bacterium Sporosarcina pasteurii DSM 33 and other strains isolated from the sand as potential candidates for MICP. Powder samples of old waste concrete fines (WCF) were mixed with urea‒CaCl2 solution, in which ureolytic bacteria can precipitate CaCO3 crystals and support their formation in WCF. Scanning electron microscopy was used to characterize the crystals according to their properties. Thus, our results suggest that MICP-prepared WCF composites could be an effective way of recycling old concrete, thereby reducing the industry’s carbon footprint.
