It should be possible to reuse plastic waste on a large scale without having to put up with an additional environmental impact during processing. Furthermore, the thermal conductivity of the insulation used should be variable according to the respective requirements. Both the method and the manufacture and operation of the device should be inexpensive, environmentally friendly and energy-saving. The potential for use should be as diverse as possible.
