“…Microwave assisted pyrolysis technique has been actively investigated for converting waste materials such as automotive paint sludge (Syed Abdul Rahman et al, 2015), sludge of biological waste water treatment plant (Lin et al, 2020), sewage sludge (Domínguez et al, 2006) and many other. The use of microwave in processing high moisture waste materials are feasible for the fact that water, being a polar molecule interacts well with the electromagnetic wave (microwave).…”

Conversion of waste to wealth has been one of the ways to reduce the volume of industrial waste to disposal site, hence reducing the impact to the environment. In this work, paint sludge from an automotive industry (APS) was converted into activated carbon through chemical activation (potassium hydroxide (KOH)) using microwave pyrolysis technique. The effect of power and radiation time on the produced activated carbon were investigated and characterised (carbon content, surface area, and pore volume) to identify the possibility of application as a supercapacitor. Potassium hydroxide activation of the APS char via microwave pyrolysis has shown that power level and radiation time has influenced the yield of the APS activated carbon. A longer radiation time and higher power supply has produced activated carbon having higher carbon contents, lower impurities, higher surface area and higher pore volume. Thus, the APS activated carbon obtained via microwave pyrolysis at power supply 1000 W and 45 minutes radiation time had produced the highest surface area and total pore volume of 434.3 m2/g and 0.2901 cm3/g, respectively. However, the produced activated carbon is not suitable for the supercapacitor application as the minimum surface area requirement must be more than 1000 m2/g. The pore size of the activated APS char produced in this study was in the range of mesopores size which was also considered very poor for supercapacitor application. The outcome of this research has shown that the produced activated carbon could otherwise be used for other application than a supercapacitor.

Automotive paint sludge (APS) contains valuable material which can be recovered by microwave-assisted pyrolysis as studied by previous researchers. In this study, combined application of microwave absorber and catalyst are studied in order to study the effect of both components in microwave-assisted pyrolysis of APS. Activated carbon and ZSM-5 acted as microwave absorber and catalyst, respectively were used to investigate their effect on pyrolytic oil produced from APS. By using One-Factor-At-Time (OFAT) analysis, results showed that at 1000W power level, 30 minutes radiation time, 6% activated carbon loading and 1.5% catalyst loading, the process was capable to produce highest oil yield of 7.75% pyrolytic oil as compared to other parameters. On the other hand, physical and chemical properties of pyrolytic oil produced via this process was also improved.
