Development and modernization have resulted in an immense increase in the production of all kinds of goods, which indirectly produce waste to the globe. Plastic was one of the materials that produce more waste due to its wide range of applications due to its versatility and relatively low cost. In most cases, thermoplastics polymer makes up a high proportion of waste and steadily increasing worldwide pollution to the environment. As a result, waste plastics pose a severe environmental challenge due to their non-biodegradable properties and disposal problems. Diverse innovations are being developed to address plastic drawbacks, which can boost the profits of the recycling industry and shrink the world plastic waste landfills. As a part of recycling, the present work is aimed to produce liquefied fuel through the nitro cracking method using pyrolysis reactor induced with bubble cap plate column with Y zeolite as a catalyst. The liquefied fuel results produced from plastic wastes (plastics bags, plastic bottles, packing materials, and medical plastics) are compared with fuel produced from virgin plastics. The 8% higher pyrolytic oil yield is achieved compared with the results of oil produced without catalyst, and 82% of total waste plastic material is converted into liquefied fuel by the presence of a catalyst. FTIR, GC-MS, Bomb Calorimeter characterize the obtained fuel results by adopting the standard ASTM methods, and the results were compared with virgin and waste plastics.

Among the modern computational techniques, Artificial Neural Network (ANN) and Adaptive Neuro-Fuzzy Inference System (ANFIS) are preferred because of their ability to deal with non-linear modelling and complex stochastic dataset. Nondeterministic models involve some computational complexities while solving real-life problems but would always produce better outcomes. For the first time, this study utilized the ANN and ANFIS models for modelling tobacco seed oil methyl ester (TSOME) production from underutilized tobacco seeds in the tropics. The dataset for the models was obtained from an earlier study which focused on design of the experiment on TSOME production. This study is an an exposition of the influence of transesterification parameters such as reaction duration (T), methanol/oil molar ratio (M:O), and catalyst dosage on the TSOME/biodiesel yield. A multi-layer ANN model with ten hidden layers was trained to simulate the methanolysis process. The ANFIS approach was further implemented to model TSOME production. A comparison of the formulated models was completed by statistical criteria such as coefficient of determination (R2), mean average error (MAE), and average absolute deviation (AAD). The R2 of 0.8979, MAE of 4.34468, and AAD of 6.0529 for the ANN model compared to those of the R2 of 0.9786, MAE of 1.5311, and AAD of 1.9124 for the ANFIS model. The ANFIS model appears to be more reliable than the ANN model in predicting TSOME production in the tropics.

“…The operation conditions used were a temperature of 500 • C, a heating ramp of 20 • C/min and a residence time of 120 min, residence time being the time in which the pellets and catalyst come into contact inside the reactor. These experimental conditions were chosen according to results reported by a previous work [52]. Before the introduction of the pellet-catalyst sample, this mixture was stirred for 10 min at 300 rpm in order to homogenize the mixture.…”

“…The use of the SnCl 2 catalyst caused a 67.57% liquid fraction, although it is a waxy fraction. This catalyst is usually used in biomass rather than in plastics [39,52,68]. Table 3 shows the performance of catalytic pyrolysis products from polyethylene film using different amounts of the HUSY-5.1 catalyst, in order to see how the amount of catalyst influences the catalytic pyrolysis, since such catalysts showed an un-waxy appearance.…”

Currently, society is facing a great environmental problem, due to the large amount of plastic waste generated, most of which is not subjected to any type of treatment. In this work, polyethylene film waste from the non-selectively collected fraction was catalytically pyrolyzed at 500 °C, 20 °C/min for 2 h, in a discontinuous reactor using nitrogen as an inert gas stream. The main objective of this paper is to find catalysts that decrease the viscosity of the liquid fraction, since this property is quite meaningful in thermal pyrolysis. For this purpose, the three products of catalytic pyrolysis, the gaseous fraction, the solid fraction and the liquid fraction, were separated, obtaining the yield values. After that, the aspect of the liquid fraction was studied, differentiating which catalysts produced a larger quantity of waxy fraction and which ones did not. The viscosity of these samples was measured in order to confirm the catalysts that helped to obtain a less waxy fraction. The results showed that the zeolites Y and the zeolites β used in this study favor the obtaining of a compound with a smaller amount of waxes than for example catalysts such as FCC, ZSM-5 or SnCl2.
