Landfill Mining

 

Measurements for detecting internal structures in landfills can be carried out in an areas of varying extent, from approximately 1 000 m2 up to several hectares. Measurements can be performed both in 2D and in 3D, but the measurements in 3D normally provide a better understanding of landfills three-dimensional internal properties. If necessary, an initial large-scale scanning over a larger area of resistivity or other geophysical method to be done to facilitate the choice of study area.

 

Resistivity and induced polarization (IP) are non-destructive geophysical methods to measure sub-surface electrical properties by electrical current being transmitted between electrodes placed at the surface. Combining measurements of resistivity and IP has proven to be a powerful tool to detect different types of materials in landfills.

Results of measurements of landfill mining can for example be used to:

 

• Locate areas with different geo-electrical properties, which, for example, can be attributed to metal content

• Visualize the distribution of various types of materials in landfills

• Provide a basis for landfill mining activities such as excavations for recycling
