Oxidative liquefaction - approach for complex plastic waste stream conversion

The oxidative liquefaction method was employed to obtain the chromatographic data. This technique has been utilized to break down the polymer matrix of various waste materials, including wind turbine blades (WTB), municipal solid waste (MSW), personal protective equipment (PPE), and photovoltaic panels (PV), in order to measure the extent of resin or total polymer degradation. In these experiments, the influence of five key parameters—reaction temperature, residence time, pressure, waste-to-liquid ratio, and oxidant concentration—on resin degradation was systematically investigated. The experiments were conducted across a range of conditions: temperatures from 200°C to 350°C, residence times from 30 to 90 minutes, pressures between 20 and 40 bar, waste-to-liquid ratios from 3% to 37.5%, and oxidant concentrations from 15% to 60% by weight. After the oxidative liquefaction process, the resulting liquid samples were analyzed using the gas chromatography (GC) method to assess the degradation products.
