A method and an apparatus for producing a shaped article or molding, which preponderantly includes plant material and a thermoplastic material, which are both introduced into an extruder. The plant material is compacted under pressure in a first extruder section and together with the thermoplastic material heated to an intended temperature at which the thermoplastic material melts. The pressure is then reduced to a value at which residual moisture of the heated material is transformed into water vapor or steam, which is removed from the extruder. The heated, dehumidified material is then compacted and extruded to the desired molding. |
