Landfill mining

Recycle more in landfills

With the new sorting concept from Norditek, more material can be recovered from old landfills. The result is a fuel, an inert fraction and magnetic metals. A win for the environment but also a win for the material owner.

The waste is sorted into three fractions

With Norditek's new concept, the waste is sorted into 3 fractions with a flip-flow screen, of which 2 fractions are wind sifted. The wind screens remove heavy material such as stone, gravel, concrete, glass and more, and the magnets can pick out metal in the heavy fraction.

Final product after handling with the concept:

• Fuel with low ash content in 2 fractions
• Inert material in 3 fractions
• Pure magnetic metal in 3 fractions

This fuel concept has been made possible by bringing together Norditek's long-standing expertise in the development and manufacture of wind screens with waste screen suppliers from Germany and Ireland.

Heavier materials can go through the windscreen

Previously, only light materials and small fractions, 0-200 mm, were allowed to pass through the windscreen, but the new version also allows heavier materials such as stone and concrete blocks up to 1 meter in size to pass through the windscreen.

Similar concepts are successfully used for waste, or recycling of old landfills. Other applications of sorting within the same concept are soil remediation, such as sorting contaminated wood from soil and rock.
