Abrégé

The invention relates to method in which a shaped body (1) is provided from plastic waste and thermoplastic material comprising natural fibre constituents or thermoplastic material and natural fibres (2). Plastic waste and thermoplastic material comprising natural fibre constituents or thermoplastic material and natural fibres are introduced into a mixing device. The materials introduced are then mixed in such a way that the materials are comminuted and at least partly melted so that, after mixing, a substantially shapeable base mass is available. This at least partly melted base mass is transferred to a mould for shaping the shaped body (1).

Abrégé

The invention relates to a thermokinetic mixer (1) for melt-mixing waste plastic products, said mixer comprising a housing (2) enclosing a mixing chamber (11), wherein a shaft (6) is provided which projects through the mixing chamber (11) and can be connected to a drive unit. Mixing blades (15) which project radially from the shaft (6) and are Y-shaped are located in the mixing chamber (10). The free end of said mixing blades projecting into the mixing chamber (10) is cuboidal, and said mixing blades have, at the end thereof opposite the free end of the mixing blades (15), two limbs each comprising at least one through-hole (22). Polygonal recesses (16) are located in the shaft (6), in which recesses the limbs (20) can be fastened by means of fastening means (17) projecting through the through-holes (22).
