Method for solidifying desert sands with enzyme‐catalysed mineralization

Abstract Sandstorms have been recognized as severe natural disasters worldwide and are currently occurring with increasing frequently due to global warming and land desertification. This study aims to mitigate their development and combat erosion caused by sandstorms and wind by improving sand‐surface stability via enzyme‐catalysed mineralization. It is an environment‐friendly method. The novelty of the reported enzymatically induced carbonate precipitation (EICP) lies in the usage of an enzyme catalyst extracted from soybeans. In contrast to the commonly used method of microbial‐induced carbonate precipitation, which is active at room temperatures between 20 and 30°C, EICP achieves high production efficiency at broader temperatures (ranging from 10 to 70°C). Four methods in appendix to EICP were chosen to solidify desert sands at the…
