 Composite are multi-layered components 
 bonded by adhesives. They are used in 
 practically all areas today. 
 Below a few examples:



 Composite waste arises in nearly every step 
 in product manufacturing. Beginning with 
 the raw material production, to 
 manufacturing of semi-finished products, 
 up to the production and manufacture of 
 products and their disposal after use.

 In the raw material production (smelting) of 
 ore from metal, waste products such as 
 dross and slag arise. Here an example of 
 the production of aluminium from bauxite,
 This composite type of residue consists of 
 a metallic aluminium and mineral 
 compound.

 In the manufacture of semi-finished 
 products e.g. laminates (coated aluminium 
 foil), production waste i.e. cuttings arise 
 during the lamination process. This 
 composite material waste consists of PE 
 and aluminium.



 In the manufacture of products e.g. 
 printed circuit boards, cuttings of copper 
 and glass fibre epoxy composite material 
 waste arise.

 At the end of its life a product such as a 
 PC ends as electronic scrap which has to 
 be disposed of. This scrap consists 
 mainly of composite materials.

 The majority of composite waste is disposed of in 
 landfill or incinerators. With this type of conven-
 tional disposal, pollution to air, ground and water 
 arises which has a considerable impact on the 
 environment. At the present time, the resulting 
 costs are not assessable. Thus, waste as a raw 
 material source is being withheld from the 
 economic cycle.

 The Result process enables industrial residue 
 and composite waste to be delaminated and 
 separated. The single fractions are returned to 
 and used in the economic cycle.

 Depending on the size and 
 nature of the composite, a pre-
 shredding to a particle size of 
 approx. 30 mm is carried out in 
 one or more operations.
 13



 14
 The pre-shredded material is 
 fed by a dosing unit to the 
 accelerator where it is then 
 delaminated. 



 15
 When the accelerator is operating, the rotor 
 revolves at an extremely high speed. Air 
 turbulences are created between the rotor tool 
 edges and the stator tool panels which produce 
 extremely high vortex or shear forces between 
 the two tool interfaces. 
 As such, multi-layered composites are literally 
 ripped apart along the different material phase 
 boundaries. The process takes advantage of 
 the different physical properties and reactions 
 or behaviours of the various materials while in 
 the accelerator. For example, metals deform 
 into a globular shape, while plastics largely 
 maintain their shape and structure (flakes).



 In various sieve layers the 
 delaminated  material mix is 
 separated according to size. 
 16



 After sieving, the fractions are 
 then separated into single 
 components according to 
 weight and structure.

  No relevant environmental 
 impact
  No use of fluids, gases or 
 other additives
  No accumulation or creation of 
 toxic substances or hazardous 
 wastes
  Input materials maintain and 
 preserve their original solid 
 state during processing
  Low energy requirement

  High recovery rate of valuable 
 substances
  High degree of purity and quality 
 of recoverable output fractions
  High degree of flexibility to 
 process a wide range of material
  Low labour costs achieved by 
 high degree of process 
 automation
  Low down-time for maintenance 
 and service
  High energy efficiency which 
 translates into low energy costs
 19



 This environmental friendly 
 and economical process 
 enables a multitude of 
 composite materials to be 
 recycled and consequently 
 returned to the economic 
 cycle, thus reducing the 
 impact on the environment 
 and resources.
