1. A method for casting a sheet of a material containing alkaloids, the method comprising:
forming a slurry of the material containing alkaloids, the slurry having a viscosity value;
storing the slurry in a first tank;
providing a first flow-path and a second flow-path for fluid communication between the first tank and a casting box, the first flow-path comprising a first pump and the second flow-path comprising a second pump;
directing the slurry either along the first flow-path or along the second flow-path from the first tank to the casting box, defining a flow of slurry through the first flow-path or through the second flow-path, on the basis of the viscosity value of the slurry; and
casting the slurry to obtain a sheet of material containing alkaloids.
