Abstract: A geothermal system including a heat-driven process system using heat extracted from a magma wellbore for driving a thermal process. The system includes a magma wellbore connected to the heat-driven process system in a closed loop. A heated heat transfer fluid conveys the heat from the magma wellbore to a reactor housing a decomposition reaction. The reactor can be a batch reactor, a continuous reactor, or a through-flow reactor. The heat provides the reaction temperature necessary for driving the decomposition reaction of a polymer to an end product. The heat can be provided directly by the heated heat transfer fluid, by an intermediate heat transfer fluid heated by the heated heat transfer fluid, or by a reaction medium heated by the heated heat transfer fluid.
