Using biocement represents an innovative approach for controlling permeability. However, achieving the desired effects in coarse sand necessitates multiple treatment cycles. This study aims to enhance the efficiency of permeability reduction by introducing kitchen waste-derived powdered shellfish and modifying precipitation patterns. Experimental findings indicate that the control group, devoid of powdered shellfish, achieved a reduction of approximately 44%, whereas the experimental groups, supplemented with powdered shellfish, experienced reductions of over 91% within the same treatment period. The significance of biocement's precipitation patterns in ameliorating permeability was substantiated through a series of experiments. These discoveries provide novel insights into optimizing biocement technology, with significant implications for potential applications, including hydraulic barrier pollution remediation schemes.
