“…When the valorification or energy recovery methods aren't possible to implement, pyrolysis is very useful because this technology is capable to process different plastic polymers and raw materials. As a result is beneficial for protecting the environment while promoting economy growth by reducing the amount of landfilled plastic and green house gases emmited into the atmosphere or to produce electricity [30]. Through pyrolysis, plastic waste can be transformed into valuble products such as oils, gas and wax.…”

“…By adding a catalyst (ZSM-5) the efficiency of the pyrolysis process can be increased which resulted in better yields for gases (5.1% to 12.2%), gasoline (from 18.2% to 34.5%) and light oil (from 17.9% to 24.1%) [67]. These valuable products can be utilized as alternative fuels in automotive industry by adding a fine modification to the engine or other application that requires thermal energy (boilers, heaters) [30,68,69].…”

Most frecquent used methods for recycling and treating plastic waste, with their advantages and disadvantages were analysed and investigated. Plastic waste present a slow degradation rate in nature, almost one thousand years, therefore it is important to address this type of pollution, by finding the most sustainable methods in reducing the percentage of plastic that ends up in landfills or in the ocean. The negative impact of plastic waste include bioaccumulation in organisms by exposure to micro and nano plastics that end up in the environment from degrading macro plastics or directly from products that contain microplastic, like exfoliating personal care products.

“…Pyrolysis is considered an economically favorable process for converting MSW into fuels, with many operational and environmental benefits. The plastic components in the MSW stream have a rich combustible composition, which can be easily converted to carbonaceous fuels by the process of pyrolysis [10]. Pyrolysis is defined as a thermal process in which controlled thermal degradation of long-chain polymeric materials takes place in an inert atmosphere in the presence or absence of a suitable catalyst.…”

“…A reduction in the overall process energy requirements and improvements in the quality of the product fuels are the major advantages of catalytic pyrolysis [23]. The oil obtained from the pyrolysis of waste plastics can be used in combustion engines, burners, and furnaces to produce thermal energy due to its high calorific values [10,[24][25][26]. As an alternative to the landfilling process, the pyrolysis process contributes to the reduction in carbon monoxide (CO) and carbon dioxide (CO 2 ) emissions.…”

The present investigation reports the results of experiments related to the conversion of low-density polyethylene (LDPE) waste carry bags to fuel through an economic catalytic pyrolysis method in a batch reactor using zinc oxide (ZnO) as the catalyst. Plastics are highly beneficial for the day-to-day activities of human beings; however, their decomposition is limited due to their strong covalent bonding. Degradation of these big molecules into smaller ones or monomers has been attempted by several researchers in recent decades, with limited success. Pyrolysis is one of the ideas used to convert plastics, with the crowded structure of polymers, into fuel rather than small molecules. Among these plastics, LDPE is widely used as carry bags throughout the world, and, herein, the results of catalytic pyrolysis of the conversion of LDPE into fuel are reported. A compact laboratory-scale batch reactor, specially designed at our laboratory, was used to carry out the pyrolysis process. Different dosages of ZnO were used as a catalyst to carry out the pyrolysis at a specific temperature. The optimal dosage of ZnO for a 50 g waste LDPE batch was found to be 0.6 g to get the maximum oil yield. The yielded oil was analyzed chemically through Fourier transform infrared spectroscopy (FTIR) and a Reformulyzer M4 Hydrocarbon Group Type Analyzer. Evaluation of physical and chemical exergy along with exergetic efficiency of the process was carried out. The described experiments and the results represent a small but significant step toward curbing the menace of plastic solid wastes, which are degrading the environment and human life worryingly, and allowing them to be utilized for generating low-cost fuel for transportation and other applications.

This article aims to review the potential and feasibility of pyrolytic oil from plastic waste (POPW) as a substitution fuel for conventional fossil fuels. Pyrolytic oil can be generated from plastic waste through the thermal cracking process. In addition to overcoming the global plastic waste problem, recovering plastic waste into alternative fuels can also reduce the consumption of fossil-based fuels. The research on POPW production and utilization of internal combustion engines (ICE) was reviewed and discussed to determine their potential and suitability for fuel substitution. Currently, plastic materials can be easily found in various product packaging, ranging from food and beverage packaging to shopping bags and appliances. When they are no longer utilized, this plastic becomes garbage and will be very harmful to humans and the environment. Therefore, it needs a correct way to proceed and minimize the impact caused by plastic waste. In fact, there are seven types of plastic waste in the polymer groups that must be handled via the pyrolysis process to avoid plastic pollution. literature survey, research on POPW via the pyrolysis process, and its usage is thoroughly found to be booming and growing very rapidly. Co-pyrolysis is known to be the most potential and suitable way to produce high-quality POPW, which is suitable to be used to fuel the ICE and also the stationary industrial engine.
