“…Dobo et al 2019 carried out pyrolysis of HDPE, LDPE, PP, PS, PET, and plastic wastes and tested pyrolytic oil in an SI engine without any modi cations or fuel blending. They obtained good results of engine performance and emissions(Dobó et al 2019). Similarly, Kumar et al received improved emissions in SI engine fueled with plastic waste pyrolysis oil(Kumar et al 2016).…”

“…However, these methods result in several economic and environmental concerns. (Bharathy et al 2019;Dobó et al 2019; Chandran et al 2020). In recent years, the investigation has switched on the recovery of energy from plastic wastes, which solves plastic waste management and generates energy as a value-added product.…”

“…It is an endothermic response where volatile matter of input plastic waste decomposes to produce condensable vapors, non-condensable gases and solid pyro-char ( xed carbon and inorganic compounds (glass, metals, ash, etc.). The inorganic compounds from pyrolysis remain unchanged which can be reused in chemical modi cation/recovery, laying transportation roads or additives for other plastics, etc., (Dai et al 2017; Rajamohan and Kasimani 2018;Dobó et al 2019).…”

With increasing population, modernization, and industrialization, plastics usage is growing daily and results in vast plastic waste. Recycling these plastic wastes to hydrocarbon fuels is challenging due to their different chemical structures, long-chain polymeric compositions, and decomposition/thermal behavior. In the present manuscript, the pyrolysis of domestic plastic waste was carried out at 473 - 973 K in a fixed bed tubular reactor and compared with individual virgin plastics, i.e. HDPE (High-density polyethylene), LDPE (Low-density polyethylene), PP (Polypropylene), and their mixture of (virgin mixed plastic). The experiments were also performed using a low-cost catalyst (mineral clay) to maximize hydrocarbon fuels. At identified optimum operating conditions, the domestic plastic waste and mixed virgin plastics yielded 73.1 wt% and 81.6 wt% liquid hydrocarbons along with 16.9 wt% and 25.5 wt.% pyrolysis gas, respectively. The composition of liquid fuels was analyzed using FTIR and GC-MS in detail, revealing a wide variety of hydrocarbons disbursement in the range of C8–C20. In addition, fuel properties of liquid fuels such as viscosity, density, fire and flash point, pour point, and calorific value was analyzed according to ASTM methods and found to be satisfactory. Based on chemical composition and fuel properties, liquid fuels derived from domestic plastic wastes showed 78.05%, and 61.86 % similarity with diesel, and jet fuels respectively. Non-condensable gases, which mainly consist of ethane and propene with minor amounts of hydrogen and methane, have been identified to be ideal for spark-ignition engine (SI) engines. This study offers a unique technique for converting waste plastics into transportation jet fuel using an affordable catalyst.

In the present study, the waste polyethylene (PE) pyrolysis under different non-isothermal conditions was investigated to estimate the optimal conversions and pyrolysis rates. The pyrolysis study was carried out using Thermogravimetry (TG) of the virgin and the waste PE under different heating rates of 5, 10, 15 and 20 C/min. The TG experiments indicated that the virgin and the waste PE pyrolysis processes mainly underwent in the temperature range of 390-510 C. Subsequently, the adaptive neural fuzzy model was adopted to predict the conversions and the pyrolysis rates of the virgin and the waste PE. The optimal operating conditions in different temperature ranges were optimized by the simulated annealing algorithm (SA). Moreover, the R-squared values of the virgin PE conversions (~1) and pyrolysis rates (> 0.999), and the waste PE conversions (~1) and pyrolysis rates (> 0.999) revealed the high accuracy of the adaptive neural fuzzy model predicted results.
