A system for continuously treating recycled polystyrene material includes a hopper/densifier configured to feed recycled polystyrene material into the system. An extruder can turn the recycled polystyrene material into a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. Solvents, such as toluene, xylenes, cymenes, and/or terpinenes can aid in generating the molten material. The molten material can be depolymerized in a reactor and a catalyst can be used to aid the depolymerizing. In certain embodiments, the catalyst is contained in a permeable container. In some embodiments, copolymers/monomers are grafted onto the depolymerized material. The depolymerized molten material can be cooled via a heat exchanger. The product can be isolated by extraction, distillation, and/or separation. In some embodiments, the product is treated through filtration and absorption media. In some embodiments, multiple reactors are used.

A synthetic resin formulation can be made using a styrenic polymer created via the depolymerization of a polystyrene feedstock. In some embodiments the polystyrene feedstock contains recycled polystyrene foam. In some embodiments, the styrenic polymer has a molecular weight similar to virgin polystyrene. In some embodiments, the styrenic polymer has a higher molecular weight and reduces the amount of virgin polystyrene needed for a synthetic resin formulation. In some embodiments, the styrenic polymer has a lower molecular weight and increases the amount of recycled polystyrene that can be used in a synthetic resin formulation by increasing and homogenizing the melt flow of the recycled polystyrene. The synthetic resin formulation can be used to make expanded, extruded, and/or graphite polystyrene foam products, as well as rigid polystyrene and ABS products.
