1. A method for high pressure treatment of bulk material by extraction, wherein the bulk material is positioned in a high pressure treatment volume of a pressure vessel apparatus and is treated at a high pressure level in a range from 40 to 1000 bar under isolation from the environment, wherein the method comprises:
pressurizing the high pressure treatment volume;
high pressure treating the bulk material in a continuous manner at the high pressure level in the high pressure treatment volume, with continuity of the high pressure treating being assured solely by way of the high pressure treatment volume, wherein the high pressure treatment volume or the pressure vessel apparatus is in a fixed arrangement while the high pressure treating occurs, wherein during the high pressure treating discontinuous gravitational force-driven displacement of the bulk material occurs through the high pressure treatment volume by multiple discontinuous rotational or translational actuating movements, wherein the bulk material is disposed in a predefined first high pressure treatment plane and is then displaced continuously or between additional high pressure treatment planes within the high pressure treatment volume during the high pressure treating by virtue of the rotational or translational actuating movements, and wherein the bulk material is selected from polymers configured as superinsulators or aerogels;
depressurizing the high pressure treatment volume; and
wherein the high pressure treating comprises a continuous extraction.
