A method of producing a bioplastic granulate on the basis of sunflower seed shells or sunflower seed hulls. In the method, ground sunflower seed shells/sunflower seed hull material is provided, wherein the particle size is in the region of 3 mm or less, preferably in the region of 0.01 to 1 mm, preferably in the region of 0.1 to 0.3 mm. A plastic material is provided, which is compounded with the sunflower seed shells/sunflower seed hull material, wherein the compounding operation is preferably effected in an extruder, preferably a double-screw extruder. The compounded material is chopped at the end of the extruder section with a tool with the addition of water, wherein the water is at a temperature of preferably more than 50&#xb0; C., preferably about 80 to 90&#xb0; C., to cool down the compound material. During the compounding operation, the compounding material is subjected to atmospheric degassing and/or vacuum degassing.
