Environmental Remediation

Assessment, clean-up planning and remediation for hydrocarbon-impacted sites.

Site-specific remediation built on assessment first.

Effective remediation starts with defining the source, extent and characteristics of contamination. Depending on site conditions, assessment may combine visual inspection, aerial observation, geophysical methods and laboratory testing.

Remediation strategies can then combine initial contaminant recovery, containment and biological or thermal treatment methods as appropriate.

Initial Clearing & Containment

Recovery of free-phase hydrocarbons
Sorbent application
Surface skimming
Hydraulic barriers and site-control measures

Bioremediation

Monitored natural attenuation
Biostimulation
Bioventing and groundwater treatment
Bioaugmentation
In-situ and ex-situ approaches

Waste & Thermal Treatment

Thermal remediation concepts
Rotary-oven treatment for suitable soils
Municipal waste utilisation concepts
Pyrolysis-based treatment options
