Bio-based soil improvement has emerged to be one of the promising solutions for low carbon and sustainability in the future. Although a considerable amount of effort has been devoted to the studies of microbially induced carbonate precipitation (MICP) and Enzyme induced carbonate precipitation (EICP) based soil improvement methods, there are still many limitations to be overcome. In this talk, some of the challenges and difficulties are highlighted. A brief summary of the recent progress on biocementation and its applications in soil improvement, including the current state-of-the-art will be presented. Field trials of some of the methods will also be introduced.
