Abstract:
In comparison to mechanical and biological technologies, plastic pyrolysis as part of a chemical recycling drew a great attention for its economic and environmental benefits. It can convert plastic waste into WPPO which can be used as a fuel or valuable raw petrochemical materials. A sample WPPO is shown in Figure 1. Pyrolysis is a possible route to utilize non-biodegradable materials as several countries are struggling with managing plastic waste. Pyrolysis of mixed plastic waste generates 50% less CO2 compared to energy recovery i.e., incineration. In addition, pyrolysis oil has several aromatic and aliphatic chemical components. Those components are quite diverse in their chemical properties as they may be cyclic, saturated, non-saturated, having long carbon chains and containing different elements such as sulfur, nitrogen, and oxygen. Analysis of the chemical elements in the WPPO is critical to value its environmental impacts. Sulfur and nitrogen can change the chemistry of the water by acidifying it and fertilize the soils. Consequently, it can negatively impact on the plants and the aquatic life. Moreover, sulfur and nitrogen can negatively impact oil refining processes by its corrosive effect and poisoning of the catalysts. Thus, it is of a great importance to quantify the sulfur and nitrogen content in the conventional and alternative energy sources.
