Restoring ecosystems through contaminated sediment treatment.

Business

Dredged Soil

Sorting, washing, stabilization and recycling of contaminated dredged soil.

CONTAMINATED DREDGED SOIL

Safely treating contaminated dredged soil and
converting it into reusable resources.

Contaminated dredged-soil treatment collects polluted sediment from rivers, lakes and ports, then applies separation, washing, stabilization and reuse to reduce disposal burden and create a foundation for ecosystem restoration.

Soil Resources does not view contaminated dredged soil as disposal-only waste. We separate useful aggregate from sludge, reuse recovered aggregate on site, and stabilize and improve contaminated fines for potential use as fill and cover material.

Contaminated dredged soil overview
Sorting & Washing

Gravel, sand and sludge are separated and washed to recover reusable aggregate.

Soil Stabilization

Leaching and dispersion of heavy metals and other contaminants are suppressed to improve treatment stability.

Aggregate & Soil Reuse

Reduces waste volume and supports circular on-site material use.

PROCESS

Project Process

After analyzing site conditions and material characteristics, each project is carried out through staged collection, treatment, reuse and restoration.

01Sediment Collection

Use dedicated sludge dredgers or site-specific collection methods

02Separate & Wash

Separate aggregate from sludge to reduce contaminated fines

03Stabilize Soil

Blend stabilizers to suppress leaching and dispersion

04Reuse & Restore

Apply recovered aggregate and stabilized soil according to site reuse potential

Contaminated dredged soil project and technology
APPLICATION

Urban river project site

Soil Resources evaluates both field applicability and reuse potential to develop project strategies balancing environmental performance and economics.

  • Polluted and urban river remediation
  • Lake and reservoir sediment dredging and treatment
  • Port and detention-basin sediment treatment
  • Dredged-soil reuse and landfill-material evaluation
