Abstract
A method for making an object with a composite material that includes at least one polymeric material in which a material of natural origin is dispersed. The method includes the steps of extruding the polymeric material in an extrusion stage; adding the material of natural origin to the polymeric material, thereby obtaining the composite material; and pressing the composite material to obtain the object. The material of natural origin is added to the polymeric material after having cooled the polymeric material downstream of the extrusion stage.

A method for making an object with a composite material comprising at least one polymeric material in which a material of natural origin is dispersed, wherein the method comprises the steps of:
- extruding the polymeric material in an extrusion stage;
- adding the material of natural origin to the polymeric material, thereby obtaining the composite material;
- pressing the composite material to obtain the object,
- wherein the material of natural origin is added to the polymeric material after having cooled the polymeric material downstream of the extrusion stage.
An apparatus for making an object with a composite material comprising at least one polymeric material in which at least one material of natural origin is dispersed, wherein the apparatus comprises:
- an extrusion stage for extruding the polymeric material;
- a cooler positioned downstream of the extrusion stage for cooling the polymeric material;
- a metering unit positioned downstream of the cooler for adding the material of natural origin to the polymeric material which has been cooled, thereby obtaining the composite material;
- a mixer for mixing the composite material;
- a pressing device for pressing the composite material, so as to obtain the object.
