This technology converts engineering muck into ecological planting soil through physical methods, achieving resource utilization of construction waste and degraded soil restoration. The process includes: screening to remove impurities → adding structure-recovering agents to prepare porous soil → mixing with 10% organic matter to activate fertility → adjusting pH to a suitable range. The technology achieves a resource utilization rate of over 85%, reduces costs by 40% compared to natural soil, and cuts annual carbon emissions by 2,000 tons.
