“…Sarker et al [34] reported that large quantities of water was produced from the pyrolysis of waste polyethylene terephthalate (PET)-a polyesterbased plastic. The pH values of the liquid products ranged from 2.18 to 3.88, as expected from pyrolysis oils derived from biogenic-rich feedstocks [16,35,36]. In all cases, the primary condensates were more acidic (lower pH) than the secondary condensates, possibly due the presence of large amounts of water which diluted the latter liquid products.…”

In this study, the effect of moisture contents [2.69 wt% (bone-dry), 5 wt% and 10 wt%] on product yields and process conversion efficiency during fast pyrolysis of a pre-treated trommel fines feedstock was investigated at 500 °C. Experiments were carried out using a 300 g h −1 bubbling fluidised bed rig. Yields of organic liquids ranged from 15.2 to 19.6 wt% of feedstock, which decreased with increasing moisture content. Hence, the bone-dry feedstock gave the maximum yield and consequently the highest process conversion efficiency of 43%. Increased moisture content also led to increase formation of unidentified gas products, indicating increased conversion of organic liquids. Due to the high ash content of the feedstocks, about 52 wt% solid residues, containing around 82% ash was recovered in the char pot in each case. Hence, to maximize oil yields during fast pyrolysis, trommel fines would require extensive drying to remove the original 46 wt% moisture as well as reducing the ash content considerably. XRF analysis of the ash in the feedstock and solid residues showed that the main elements present included Ca, Si, Fe, Pb, K, Cl and Al. Apart from the presence of Pb (which may be from the glass contents of the feedstock), the solid residues could be used for land reclamation or co-incinerated at cement kilns for cement manufacture.

“…In addition, pyrolysis and gasification of OFMSW are also promising methods [16] and result in the formation of valuable CO and H 2 -rich syngas, liquid, and solid residue (char) [17]. The obtained syngas can be used as a feedstock for methanol or Fischer-Tropsch synthesis [18], while the liquid product can be used as an alternative hydrocarbon source for fuel and other high-value chemical production [19], i.e., pyrolysis and gasification can contribute to the reduction of landfilled waste providing a better waste treatment option [20] and alternative energy production at the same time [21]. Due to the abovementioned reasons, this treatment of MSW gained significant attention among researchers in the past years and several scientific papers and reviews have been made in the topic of pyrolysis and gasification [22].…”

The increasing environmental consideration and the growth of instability of the energy market call for methods that can process the organic fraction of municipal solid waste (OFMSW) into fuel instead of disposal. Due to the pyrolysis and gasification that are efficient procedures to achieve valuable products, gasification of OFMSW with different particle sizes and compositions was carried out in the presence of Ni and Ni-Ce-loaded Y-zeolite in a multizone tubular kiln reactor. During the experiments, 500°C was applied in the first reactor zone, while the 2nd zone was at an elevated temperature of 600°C or 900°C in the presence of steam. The combined pyrolysis and gasification experiments were also carried out without a catalyst with the same operating conditions. The feedstock was collected from the organic fraction of a Hungarian mechanical-biological treatment (MBT) plant and was separated into four different fractions based on particle size: <1 cm dry biomass and fine particles, 1-2 cm paper-rich, 2-6 cm paper and plastic-rich feedstocks, and <6 cm mixture of these fractions. During the experimental work, product yields; gaseous product composition; the ratio of H2/CO, CO2/CO, and CH4/CO; and lower heating value were determined in the function of feedstock composition, the applied temperature, and catalysts. It was found that the hydrogen content and H2/CO ratio of gaseous products were increased due to catalyst application and temperature elevation in the 2nd reactor zone. The addition of Ce to the Ni/Y-zeolite catalyst was advantageous in the case of hydrogen formation at a lower temperature (600°C). The hydrogen and methane content of products obtained from the catalytic pyrolysis-gasification of paper and plastic-rich OFMSWs on elevated temperatures were higher, which increased the lower heating value of those products. Based on the elemental analysis of the obtained solid residues, it was found that paper/plastic-rich feedstock released hydrogen and carbon with a higher extent. 1-2 cm feedstock-related solid residues had the highest H/C ratio which caused a 12.5-12.8 MJ/kg gross heating value. As a result, combined pyrolysis and gasification appear to be an efficient method to attain valuable outputs from OFMSW not only in gas but also in solid products.

“…Islam et al. [ 24 ] experimented with extracting pyrolytic oil from municipal solid waste at 400–550 °C, in which cellulosic biomass (organic food waste) was the primary raw material. The authors used scrap tires, waste paper, and plastic in an externally heated feed reactor pyrolysis system and analyzed and compared the pyrolytic fuel properties with petroleum-based oil.…”

The paper aims to study different aspects of liquid fuel production through pyrolysis from agricultural residues, MSW, and e-waste available in Bangladesh. The abundant production of various crops generates massive amounts of residue such as rice straw, wheat straw, rice husk, jute stick, and sugarcane bagasse in Bangladesh have great potential for liquid fuel production for pyrolysis conversion. Bangladesh produces almost 25,000 tons of solid waste per day from urban areas, and Dhaka city alone contributes to one-quarter of all urban waste in the country. The biomass and waste-derived pyrolysis fuel can be successfully used in turbines, boilers, engines and upgraded to high-quality hydrocarbon transportation fuels through distillation. The concise data obtained from the study is anticipated to provide valuable information regarding the effective utilization of municipal solid waste and agricultural residues by using pyrolysis process so that further detailed work on these resources can pave a pathway towards scientific research and significant energy contribution in Bangladesh. The feasibility study has been conducted through physical properties, proximate analysis, elemental analysis, and thermogravimetric analysis of the selected agricultural residues, municipal solid wastes, and plastic e-wastes for pyrolysis conversion in Bangladesh. It has been found that polythene has a better thermochemical potential than rice straw (13.71 MJ/ kg) owing to its high calorific value (46.41 MJ/kg). The foremost volatile matter obtained from plastic waste is 98.1 wt.%, and the minimum from rice husk is 57.19 wt.%. The maximum carbon amount is possessed by plastic waste (84.03 wt.%). The ultimate analysis showed that the MSW sample contains more sulfur content than agricultural residue and e-waste, whereas the case is the opposite in terms of oxygen. Rice husk and tire waste have the highest ash content, i.e., 19.70 and 4.38 (wt.%), respectively, indicating a significant amount of unwanted material. TGA examination of feedstock revealed that the majority of mass loss occurred between 250-450 C for agricultural residue attributed to the release of volatile materials during the formation of char and the evolution of pyrolysis gases. For MSW samples, the range varies between 350-500 C, which is the appropriate temperature for optimizing liquid oil production in plastic pyrolysis.
