Patents
Patented technologies for dredged-soil recycling, soil improvement and sludge treatment.
Verified patent technologies for
sediment treatment and ecosystem restoration
Soil Resources delivers environmental restoration projects backed by intellectual property and field verification in dredged-soil separation, soil improvement, sludge recovery and contaminated dredged-soil recycling.
Our patents are more than equipment ownership; they provide the technical basis for converting contaminated sediment and sludge into resources while improving process stability and reuse potential.
Recycling methods and plant technology for contaminated dredged soil
Sorting and washing plant technology based on Soil Washing
Sludge-soil improvement and stabilization technology
Aquatic restoration using recovered materials
Key Patents
Our core patents in sediment treatment, soil-improvement plants, dredged-soil reuse and sludge improvement support treatment and restoration solutions tailored to site conditions.
Technology for improving contaminated dredged soil classified as waste so it can be used as fill, cover and similar materials.
Integrated treatment that separates dredged soil by particle size and improves sludge to increase treatment efficiency and reuse potential.
Technology that converts polluted river dredged soil into reusable material, reducing waste and supporting circular use.
Technology that stabilizes sludge through soil improvement and produces improved soil for cover, planting and other uses.
Equipment and process technology that efficiently blends sludge and amendments to improve treatment performance and plant efficiency.
Patent technologies are verified through testing and field application.
Verification covers contaminant reduction, aggregate quality, dredging-water treatment, soil-property improvement and other project-specific criteria to strengthen process reliability.
Checks changes in heavy metals, TPH, organic compounds and compliance with applicable criteria.
Reviews specific gravity, absorption, clay content and other properties after washing and separation.
Verifies effluent quality and treatment efficiency for SS, BOD, COD, heavy metals and related parameters.
Reviews CBR, compaction, moisture and other improved properties for intended reuse.
