Claims

1. Method for the bulk determination of scrap metal content, said method comprising the steps of

- providing a scrap metal input;

- preparing said input for submission to a bulk scanning apparatus; - scanning at least part of the scrap metal with a bulk scanning

apparatus to determine the composition of the scrap metal;

and securing said scrap metal from the step of providing the scrap metal input to the step of scanning at least part of the scrap metal.

2. Method according to claim 1, wherein the step of preparing said input comprises reorganizing said input to obtain a substantially

predictable reorganized arrangement comprising the scrap metal.

3. Method in accordance with any of the previous claims, wherein the scrap metal comprises ferrous and/or non-ferrous scrap metal.

4. Method in accordance with the previous claims, wherein the scrap metal further comprises one or more contaminants selected from the group consisting of moisture, plastics, oil, steel, minerals or combinations thereof; and determining the composition of scrap metal comprises determining the ferrous or non-ferrous metal content versus contaminants content.

5. Method in accordance with any of the previous claims,

comprising subsequent to the step of scanning, loading the scrap metal into a transportation container and seahng the loaded transportation container, wherein said method preferably further comprises further securing,

preferably visually monitoring, of said scrap metal from the step of scanning to the step of loading the scrap metal into the container.

6. Method according to any of the previous claims, further

comprising comparing the composition of the scrap metal as determined in the scanning step with the composition of the scrap metal as determined in a separate previous scanning step, wherein the separate previous scanning step was carried out using a scanning apparatus of the same type as said bulk scanning apparatus, preferably using a substantially identical bulk scanning apparatus.

7. Method in accordance with any of the previous claims, wherein the securing of the scrap metal comprises safe guarding the scrap metal against undetected tampering, monitoring, preferably visually monitoring the scrap metal, tagging or labeling the scrap metal, monitoring the environment of the scrap metal, or a combination thereof.

8 Method in accordance with any of the previous claims, wherein the step of preparing said input for submission to a bulk scanning apparatus comprises arranging said input in a three-dimensionally arrangement, preferably arranging said input in a scanning container.

9. Method in accordance with any of the previous claims, wherein the scanning comprises scanning of at least part of the scrap metal that is obstructed from sight upon visual inspection of the scrap metal.

10. Method in accordance with any of the previous claims, wherein the scanning comprises cutting, magnetic sensing, low-intensity neutron scattering, or a combination thereof, preferably mechanical cutting and

laser cutting, more preferably mechanical cutting and laser cutting comprising laser-induced breakdown spectroscopy.

11. Method in accordance with claim 10, wherein the magnetic sensing comprises placing at least part of the scrap metal in a magnetic field ranging from 5 to 100 Gauss, preferably 10 to 40 Gauss and detecting magnetic field changes by one or more Hall sensors.

12. Method in accordance with any of claims 10- 11, wherein the low-intensity neutron scattering comprises determining content of hydrogen atoms in at least part of the scrap metal.

13. Method in accordance with any of the previous claims, wherein the step of scanning comprises more than 50, preferably more than 100, more preferably more than 500, most preferably more than 1000

independent measurements of the scrap composition.

14. An apparatus for reorganizing and scanning a scrap metal input, said apparatus comprising a scanning container together with a low-intensity neutron scattering device, a laser cutting device and/or magnetic sensing device.

15. An apparatus in accordance with claim 14, wherein the scanning-container is cylinder-shaped and comprises a wall that comprises one or more openings such that during operation, the laser cutting device that is positioned outside the scanning container can project a laser beam inside the scanning container through one or more openings.
