Heavy　metal　pollution　in　landfill　soil　poses　a　dual　challenge　of　environmental　toxicity　and　resource　depletion.　Enzyme-induced　carbonate　precipitation　(EICP)　was　systematically　evaluated　as　a　sustainable　stabilization　method　for　cadmium　(Cd),　lead　(Pb),　and　chromium　(Cr)　under　both　solution-　and　soil-phase　conditions.　Laboratory-scale　experiments　demonstrated　that　EICP　achieved　over　80%　removal　efficiency　for　Cd,　Pb,　and　copper　(Cu)　in　solution-phase　systems,　while　soil-phase　trials　focused　on　Cd,　Pb,　and　Cr　to　simulate　realistic　field　conditions.　Optimal　performance　was　achieved　using　a　1:1　molar　ratio　of　soybean-derived　urease　(1.0　U/mL)　to　CaCl2　(0.5　M),　with　Cd　stabilization　reaching　91.5%.　Vacuum-assisted　filtration　improved　treatment　uniformity　by　29.2%　in　clay　soils.　X-ray　diffraction　identified　crystalline　otavite　in　Cd　systems,　while　Pb　and　Cu　were　stabilized　via　surface　adsorption.　Sequential　extraction　confirmed　that　over　70%　of　Cd　was　transformed　into　carbonate-bound　phases.　Treated　soils　met　TCLP　leaching　standards　and　reuse　criteria,　maintaining　neutral　pH　(7.2–8.1)　and　low　salinity.　Compared　to　cement-based　methods,　EICP　avoids　CO2　release　from　calcination　and　fossil　fuel　use.　Carbon　in　urea　is　retained　as　solid　CaCO3,　reducing　emissions　by　0.3–0.5　t　CO2-eq　per　ton　of　soil.　These　findings　support　EICP　as　a　scalable,　low-carbon　alternative　for　landfill　soil　remediation.　©　2025　by　the　authors.
