Enzyme-induced carbonate precipitation (EICP) is an emerging technology for ground improvement that cements soil particles with calcium carbonate to increase strength and stiffness. EICP technique has been investigated as bio-cement for several ground improvement applications such as liquefaction mitigation and improvement of soil compressive strength. Despite the potential of this technique as ground improvement, several obstacles limit the commercial adoption of EICP. One of these obstacles is the lack of standard procedure to optimize the EICP cementing solution constituents in the light of the reaction kinetics. In addition, few studies have explored the combination of EICP cementation with other mechanical improvement techniques such as geosynthetics. This study investigates the effectiveness of enzyme-induced carbonate precipitation (EICP) for soil stabilization and compares it with Portland cement (PC) stabilization. The research findings provide valuable insights into the kinetics, unconfined compressive strength (UCS), triaxial and dynamic behavior, geogrid reinforcement, and life cycle assessment (LCA) of EICPtreated soils. The experimental results from EICP kinetics and tube tests reveal those higher concentrations of urease enzyme and non-fat milk lead to increased conversion efficiency, pH, and electrical conductivity. The best performance is observed for solutions with 9 g/L urease and 12 g/L stabilizer. Kinetic modeling of the EICP process demonstrates good agreement with experimental data, validating the accuracy of the model. The study highlights the influence of pH and electrical conductivity on conversion efficiency, with urease hydrolyzing urea and causing pH changes Non-fat milk, specifically casein protein, enhances the reaction by serving as nucleation sites for CaCO3 precipitation and stabilizing urease activity. However, casein micelles' stability decreases in low pH, high ionic strength, and high soluble calcium environments. The complexity of the EICP process necessitates further kinet
