scrap metal


REDWAVE guarantees the highest value of recycling plants and optical sorting machines based on years of experience in the recycling industry.


Recovery of recyclables from Waste Electrical and Electronic Equipment (WEEE)

  • Metals and alloys

  • Plastics (thermoplastics, plexiglass, etc.)

  • Composite materials (circuit boards, etc.)

  • Brominated plastics (BFR)

  • Plastics with cadmium compounds

  • Material tainted with precious or recoverable metals (e.g. copper, brass, silver, etc.)

  • Sorting of monitor glass (CRT)

The trend for more and more electronics with an ever shorter life cycle continues to dominate. The processing of such appliances and machines can highly profitable. The recovery of precious metals and other types of metals and plastics (PCBs, etc.) are the main focus in sorting technology.

The recovery of

  • Type sorting of ferrous metals (e.g., stainless steel)

  • Type sorting of non-ferrous metals (such as aluminium, copper, brass, bronze, zinc, stainless steel)

  • Critical raw material (e.g. tungsten from mobile phones)

  • Printed circuit boards

  • Plastics

  • Glass

  • Composite materials

Sorting of

  • Various aluminium groups

  • Plastics

  • Various scrap metals

Metals can be identified according to the colour, nature of the metal and of elemental composition.

Possible applications:

  • Sorting of slag: separation of various metals from a mixture of slag and metals

  • Sorting of aluminium

    • Separation of various impurities of metallic origin (Cu, Zn, VA, brass, Pb etc.)

      • further separation of these fractions (see below: sorting of non-ferrous metals and other metals)

    • Separation of various impurities of different origin (e.g. wood, plastics) by means of camera technology

    • Separation of aluminium alloys with a higher Zn or Cu content. We are able to produce for instance the alloy 6061 by separating Al alloys with Zn and Cu contents of a few percent

  • Sorting of stainless steels

    • Separation of impurities such as Cu, Zn, brass, Pb, Sn in pure form and in the form of alloys. A pure fraction of steel / stainless steel is produced.

    • Separation of stainless steels from a mixture of steel and stainless steel.

    • Separation of stainless steels with Mo contents according to adjustable Mo concentration

    • Separation of stainless steels with Ni contents according to adjustable Ni concentrations

  • Sorting of non-ferrous metals and other metals

    • Separation of Cu, Zn, brass etc. in pure fractions

      • Production of a pure Cu fraction

      • Production of a pure brass fraction

      • Etc.

  • Sorting of precious metals

    • Separation of materials containing Au

    • Separation of materials containing Ag

  • Special applications

    • Sorting of Cu tubes

      • Separation of Ag soldering joints

      • In general: Sorting of various alloys on the basis of differences in the composition of the elements, e.g. presence of an element in alloy A, which is not existent in B and C, etc.
