Best Practices in Contamination Control for Waste Plastic Thermo-conversion

This case study outlines best practices in contamination control during waste plastic thermo-conversion processes, specifically focusing on the pyrolysis oil production from waste plastics. The document begins by addressing the urgent issue of end-of-life plastic waste, which significantly contributes to environmental contamination. It explains the pyrolysis process, where waste materials are incinerated at high temperatures without oxygen to produce pyrolysis oil. The study highlights the challenges posed by variable quality and contaminants in the waste plastic feedstock, which can affect the quality of the produced pyrolysis oil. A pragmatic action plan was developed to sample and analyze the contamination levels in the pyrolysis oil. The results indicated that a combination of Pall depth filter modules and liquid/liquid coalescers effectively removed contaminants, improving the oil's quality. The conclusion emphasizes the enhanced reliability and productivity of the pyrolysis process, leading to reduced operational costs and higher product value.
