Flow Through Process for Thermal Depolymerization and Monomer Repurposing using Geothermal Energy

A method for a magma-driven decomposition reaction, the method comprising:

• receiving a polymer and a reaction medium into a reactor body configured to house a decomposition reaction of the polymer into an end product, wherein:
• the decomposition reaction occurs in the reaction medium at a reaction temperature;
• the reactor body houses a filter disposed between an inlet end and an outlet end of the reactor body;
• the filter is configured to prevent the polymer in the reactor body from passing through the outlet and to permit a reaction medium to carry the end product through the filter and out of the outlet;
• exposing the reaction medium and the polymer to the reaction temperature for a residence time by heat absorbed from a wellbore extending from a surface to an underground reservoir of magma;
• and
• conveying the end product and the reaction medium through the filter and out of the outlet after the residence time.
