Soil clean-up

Soil remediation and civil projects often generate soil, debris and other materials, which, depending on their composition, may be suitable for reuse. BAM Milieu determines for you which materials are reusable and, on request, looks for an appropriate use. If reuse is impossible, the material has to be cleaned or dumped. We handle biological and extractive clean-ups for which we have our own cleaning installation, as well as thermal clean-ups.

Biological soil clean-up

This method is suitable for degradable organic materials, such as light mineral oil and PAHs with a low number of rings in sandy soil. We create optimal circumstances, enabling the micro-organisms in the soil to break down the pollutants, in which the following factors play a role:

• Bioavailability: the degree to which pollutants are available for conversion by micro-organisms
• Presence of the required micro-organisms
• Environmental conditions: availability of oxygen, presence of nutrients, temperature, moisture content, pH, redox potential, absence of toxic substances

Extractive soil clean-up

This is an off-site method for removing pollution from the ground using a combination of techniques. Volatile and easily soluble contaminants can be removed almost completely. Heavy metals, PAHs and pesticides are removed less efficiently. The method is also suitable for cleaning-up:

• various types of sludge (from sewers, lock chambers, pumping stations, ground cleaning residue)
• spoil
• (ballast) gravel

After clean-up, the materials can be used as secondary building materials.

Thermal clean-up

Thermal clean-ups are suitable for the clean-up of all organic pollutants as well as inorganic pollutants such as cyanides, mercury and mercury compounds. A thermal clean-up is capable of reaching the prescribed end concentrations regardless of the baseline concentrations.

Our clean-up units

In Assendelft we operate a physical-mechanical separator for extractive soil clean-ups, which we use to clean soil and different kind off sands (ground cleaning residue, filtering gravel, spoil, silt, (ballast) gravel and debris). The unit has its own unloading wall, a weighbridge and ample space for the receipt and storage of liquid and forkable materials.
