The present invention relates to upgrading heavy petroleum oils, their residues, and/or polymeric materials. More specifically the present invention relates to a method for upgrading heavy petroleum oils, their residues, and/or polymeric materials by hydrothermal treatment with an aqueous solvent. 171-. (canceled)72. A method for converting a polymeric feedstock into a product , the method comprising the stages of:treating a mixture of(i) the polymeric feedstock,(ii) any one or more of lignite, lignocellulosic biomass, plant gum, plant resin, plant tar, plant pitch, and(iii) an aqueous solvent;at a temperature of more than 370° C. and at a pressure of more than 20 bar for a suitable time period, anddepressurising the mixture to obtain a product,wherein the product comprises bio oil, wherein:the reaction mixture comprises at least 40% wt/wt of the polymeric material, andthe polymeric material is selected from the group consisting of Polyethylene (PE), Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polypropylene (PP), Polyester, Poly(ethylene terephthalate) (PET), poly(lactic acid) PLA, Poly (vinyl chloride) (PVC), Polystyrene (PS), Polyamide, Nylon, Nylon 6, Nylon 6,6, Acrylonitrile-Butadiene-Styrene (ABS), Poly(Ethylene vinyl alcohol) (E/VAL), Poly(Melamine formaldehyde) (MF), Poly(Phenol-formaldehyde) (PF), Epoxies, Polyacetal, (Acetal), Polyacrylates (Acrylic), Polyacrylonitrile (PAN), Polyamide-imide (PAI), Polyaryletherketone (PAEK), Polybutadiene (PBD), Polybutylene (PB), Polycarbonate (PC), Polydicyclopentadiene (PDCP), Polyketone (PK), polycondensate, Polyetheretherketone (PEEK), Polyetherimide (PEI), Polyethersulfone (PES), Polyethylenechlorinates, (PEC), Polyimide, (PI), Polymethylpentene (PMP), Poly(phenylene Oxide) (PPO), Polyphenylene Sulfide (PPS), Polyphthalamide, (PTA), Polysulfone (PSU), Polyurethane, (PU), Poly(vinylidene chloride) (PVDC), Poly(tetrafluoroethylene) PTFE, Poly(fluoroxy alkane) PFA, Poly(siloxanes), silicones, ...
