“…A mixture of HDPE, LDPE and PP with oil shale was pyrolysed for fuel production by Aboulkas et al (2012) where pyrolysis oil with plastics was produced at higher rates by comparison to pyrolysis without plastics which acted as a promoting materials for degradation. Chattopadhyay et al (2016) co-pyrolysed biomass in the form of paper with a mixture consisting of HDPE, PP and PET in a catalytic process using a FBR. An optimal gas product evolution was determined in the biomass/plastics ratio of 5:1 with the presence of the catalyst which yielded a hydrogen gas of 47 vol%.…”

Plastic plays an important role in our daily lives due to its versatility, light weight and low production cost. Plastics became essential in many sectors such as construction, medical, engineering applications, automotive, aerospace, etc. In addition, economic growth and development also increased our demand and dependency on plastics which leads to its accumulation in landfills imposing risk on human health, animals and cause environmental pollution problems such as ground water contamination, sanitary related issues, etc. Hence, a sustainable and an efficient plastic waste treatment is essential to avoid such issues. Pyrolysis is a thermo-chemical plastic waste treatment technique which can solve such pollution problems, as well as, recover valuable energy and products such as oil and gas. Pyrolysis of plastic solid waste (PSW) has gained importance due to having better advantages towards environmental pollution and reduction of carbon footprint of plastic products by minimizing the emissions of carbon monoxide and carbon dioxide compared to combustion and gasification. This paper presents the existing techniques of pyrolysis, the parameters which affect the products yield and selectivity and identify major research gaps in this technology. The influence of different catalysts on the process as well as review and comparative assessment of pyrolysis with other thermal and catalytic plastic treatment methods, is also presented.

“…The close values of the quantitative yield of coking products for these experiments lead us to the conclusion that at the selected ratio of solid and liquid phases, the quality of the liquid phase used does not affect the yield of thermolysis products. Earlier, in [24,32,33], the synergistic effect was demonstrated in the processes of the joint thermolysis of various types of waste, including those with oil residue. At present, research results obtained show the feasibility of co-coking different types of organic waste and their mixtures with long residuum.…”

“…Joint pyrolysis of plastic waste with other materials (including petroleum residue) increases the yield of liquid products and reduces their viscosity [33]. Research results [24,32,33] demonstrate the possible benefits of the joint thermal processing of various types of waste with oil residues to produce fuels from waste.Waste tires contribute significantly to the global solid waste flow [34], which calls attention to the problem of their utilization. Today, waste tires are considered potentially effective raw materials.…”

“…Recently, considerable attention has been drawn to microwave-assisted pyrolysis [29][30][31], although the technology needs further development.In a number of waste management scenarios, the wastes are not sorted (which is typical, e.g., for Russia), so it is necessary to consider the possibility of joint processing of various types of waste. Joint catalytic pyrolysis of paper and plastic waste creates a synergistic effect on the yield of liquid products [32]. Joint pyrolysis of plastic waste with other materials (including petroleum residue) increases the yield of liquid products and reduces their viscosity [33].…”

An Investigation of the Feasibility of the Organic Municipal Solid Waste Processing by Coking

In the context of transition to a circular economy, one of the strategic priorities is the development of technological innovations aimed at waste processing. In this study, the foundations have been developed for a low-temperature, environmentally safe method for efficient processing of organic municipal solid waste, which may be further applied for processing both municipal and industrial waste organics in order to obtain liquid products. The maximum yield of liquid products is ensured when conducting the coking of a mixture of organic waste with long residuum in the temperature range of 400-420 • C, with a heating rate of 5-70 • C/min, and with an optimal heating time to the coking temperature of 80 min. Recommendations on the use of the waste recycling products are given. The proposed process is consistent with the principles of circular economy and does not require external energy costs because the energy needed for the process is generated by burning the gas produced during the waste coking. The process does not produce emissions into the environment and, in combination with standard refining processes, can be used to obtain commercial petroleum products.Thermal methods of waste processing include incineration, torrefaction, pyrolysis, gasification [8,12]. The disadvantage of thermal waste processing methods is their high costs. These methods do not provide environmental safety of the process, and the products obtained are not suitable for use without additional quality improvement with the help of expensive processes. For instance, to increase the thermal efficiency of energy production from moisture-containing waste by pyrolysis and gasification, preliminary drying of raw materials is required, which increases operating costs. In thermal processing of waste, secondary slags are formed that require further utilization or disposal. The exhaust gases contain toxic compounds and require neutralization. Environmental impact caused by the processes of generating energy from waste was analyzed in review [13]. The points among all are local impacts from wood combustion and processes of the solid recovered fuel generation, also it should be noted that the innovative technologies applied to thermochemical processes at the waste-to-energy plants do not give absolute advantages in preventing environmental pollution.Processing of MSW is considered also as an opportunity to produce motor fuels, olefins and aromatic compounds [14,15]. In view of the fact that municipal solid waste can also contain non-combustible substances, there is a problem with the necessity of an expensive pre-treatment stage [16].There are a number of studies on thermal and catalytic decomposition of plastic waste [17][18][19][20][21][22]. The quality of plastic waste products derived through pyrolysis depends on the composition of the raw materials, and the effect of catalysts [19,23]. Joint catalytic processing of plastic waste and heavy oil residues is considered as a possible way to obtain fuel oil [24]. Cai et al. [25] offer alternative techn...
