From Landfills to Prime Land: Unlocking the Value of Contaminated Sites

What used to be “outskirts” landfills are now sitting in the heart of growing cities.
But here’s the challenge:
Many of these sites contain mixed waste — municipal, construction, and industrial — with little historical control, leading to long-term environmental risks:
▪ Leachate contaminating groundwater
▪ Methane and greenhouse gas emissions
▪ Residual heavy metals and organic pollutants
So how do we safely remediate and unlock land value?
Common Remediation Strategies
1.In-situ (Containment-based)
Best for risk control:
✔ Capping systems
✔ Landfill gas management
✔ Groundwater monitoring

2.Ex-situ (Excavation & Treatment)
Increasingly preferred for redevelopment projects:
Screening → Soil Washing → Targeted Treatment
Screening: separates waste and soil
Soil washing: reduces contaminated volume (key step)
Thermal desorption / S/S / Bioremediation: final polishing

Why Soil Washing Matters
In most cases, contaminants are concentrated in fine particles.
Soil washing enables:
✔ Significant volume reduction
✔ Lower overall remediation cost
✔ Higher material recovery
Modular soil washing systems (like Desen’s solutions):
Compact footprint
Fast deployment
Easy relocation
Ideal for multi-site operations
Industry Trends
✔From containment → redevelopment
✔From single solution → integrated systems
✔ From disposal → volume reduction & reuse
Landfills are no longer just liabilities —
they are opportunities for urban transformation.
