The increasing demand for plastics for their widespread applications has ultimately resulted in accumulation of substantial plastic waste, which remains a concern due to limited efforts, inadequacy, and environmental distresses of conventional techniques for waste plastics remediation. The enhanced production of raw materials for polymer syntheses has a dual impact on our ecosystem by causing rapid depletion of nonrenewable petroleum resources and waste generation. To address this situation, researchers have adopted advanced thermochemical recycling processes to produce intermediate products of the petrochemical industries including monomers, fuels, and other value-added products. Such practices can potentially serve the purpose of a circular economy. This review aims to cover the recent highlights in the field of waste plastics pyrolysis including critical observations from the past to provide precise understanding. Consequently, the reactivities and product distributions for plastic feeds, pyrolysis reactors, roles of catalysts, and effects of operating parameters on reactivity and selectivity have been covered. Coprocessing of plastic waste with radioactive materials, biomass, and heavy petroleum residue is also discussed. Furthermore, an overview on kinetics and mechanistic aspects of plastic pyrolysis is presented with a discussion on relevant analytical techniques. The applications of pyrolysis oil as a fuel or fuel additive are comprised in a separate section. Lastly, comparisons of existing chemical recycling technologies, summaries of commercial operations, and future projections are provided.

“…It is also evident from the properties of plastic fuel, which are responsible for poor combustion inside the cylinder. The hydrocarbon emission can be reduced by improving the properties of plastic oil with higher oxygen content fuel, so that the hydrocarbon emission coming in the exhaust can undergo combustion inside the cylinder [6,7]. The HC emissions are minimum for diesel and for blend HC emission increases by 17% for P20.…”

“…The plastic oil blends can be considered as alternative fuel for diesel engines with acceptable performance addressing the environmental concerns as well [6]. The experimental outcomes indicated that the performance with plastic oil blends were comparable to diesel operation while the fuel consumption decreased marginally with WPO and diesel fuel blends [7]. The process of obtaining fuel from the plastics is an important source of energy.…”

Recycling of waste plastics for power generation, automotive traction can provide perfect source of energy due to their energy content. Plastics utilization is growing daily although it is not environment friendly material but can be utilized for different applications. The disposal of after use plastic is a major task and quality of oil obtained from the same has properties similar to fuel. The main advantage of conversion of used plastic to gasoline provides additional fuel generation to be derived besides addressing the disposal issues. The plastic oil obtained from pyrolysis can be added with conventional fuel efficiently and acceptable engine overall performance. Therefore, blends of plastic oil with diesel are considered for the diesel engine applications. In the present study pyrolysis of plastic is done in presence of catalyst at temperature of 380°C to obtain oil with properties similar to petroleum fuels. The plastic oil is mixed with diesel in different volume proportions ranging from 10 to 40% and used as fuel in diesel engine to study its characteristics. Properties of plastic oil blends with diesel obtained were analysed. The lower plastic oil blends P10increased the brake thermal efficiency by 5%and lowered the rate of fuel consumption by 10%. As the blending ratio increased in-cylinder pressures and heat release rates were higher and the longer ignition delay were obtained. The emissions of HC, NOx decreased with lower plastic oil blending as compared to higher blending ratio. The result suggests that the plastic oil P10 can be used effectively as alternative fuel to diesel for engine with optimized operating situations. Utilization of PO with diesel blends of 10 to 30% in conventional engines provide acceptable engine performance and reduction in emission and hence can effectively reduce the dependence on fossil diesel fuel and reduce the foreign exchange.

“…Viswanath et al [25] also concluded that brake thermal efficiency of blends are lower compared to diesel, but 25% blending shows similar performance to that of diesel. Syamsiro et.al [26] also found that brake thermal efficiencies of waste polyethylene oil (WPO) are quite higher as compared to that of diesel. However, the difference was not significant since the calorific value of WPO which is found to be similar than that Some studies above have shown that the pyrolysis of plastic wastes become oil product was conducted a good result.…”

In recent years, there has been growing interest in alternative energy sources to fossil fuels. One of them is plastic pyrolysis oil (ppo) that converted from plastic waste by the pyrolysis process. The oil could be used as a fuel for combustion process in some industries. The performance of ppo combustion in steam-atomizing burner was investigated to determine the feasibility of diesel oil displacing in pyrolysis process heating. A prototype steam-atomizing burner was installed to burn plastic pyrolysis oil, with variable 3, 6, and 9 bar steam pressure, to pyrolyze 10 kg/batch low density polyethylene (LDPE) waste in a batch reactor. The pyrolysis process was maintained at 3500C along 2 hours at atmospheric condition. The flame temperature, the length of flame, fuel consumption, heating rate, and pyrolysis yield was observed along the process. The experiment shows that the increase of steam pressure will increase all parameters. The most optimum condition is plastic pyrolysis oil combustion using steam-atomizing burner at 9 bar steam pressure, which consumes 28 litre of fuel and yields 57% of pyrolysis oil.
