“…The TGA curves of PET exhibit four distinct stages of thermal degradation, which are likely indicative of various compound fragments within the polymer structure as it undergoes thermal decomposition. This finding aligns with previous research [19]. During the initial stages, the weight loss can be attributed to CO 2 and CO liberation, followed by the release of C…”

In order to improve the thermal insulation properties of fired clay bricks, the addition of polystyrene has been a common practice. However, in this study, we propose an alternative approach by substituting polystyrene with recycled polyethylene terephthalate (PET) derived from drinking water bottles. The PET is shredded and added to the brick composition, with a maximum inclusion level of 25%. Various tests were conducted to evaluate water absorption, apparent porosity, bulk density, cold crushing strength, and thermal conductivity of the bricks at temperatures up to 800 degrees Celsius. The results indicate that incorporating 20% crushed plastic by weight yields bricks comparable to ASTM C155-97 standard bricks.

“…As long as pyrolysis is a process used to produce high-energy fuel, our comprehension of changes in enthalpy, entropy, and free energy with different heating rates must consider thermodynamics (Enyoh et al (2022) [ 28 ], Xu and Chen (2013) [ 29 ]). Chowdhury et al (2023) [ 16 ] computed the thermodynamic parameters using the kinetics parameters obtained by the CR and Arrhenius models.…”

The pyrolysis of polyethylene terephthalate (PET) is a well-known process for producing high fuel value. This paper aims to study the kinetics of PET pyrolysis reactions at 4 different heating rates (2, 5, 10, and 20 K min−1) using thermogravimetric analysis (TGA) data. TGA data show only one kinetic reaction within the temperature ranges of 650 to 750 K. Five different model-free models, namely, the Freidman (FR), Flynn–Wall–Qzawa (FWO), Kissinger–Akahira–Sunose (KAS), Starink (STK), and distributed activation energy model (DAEM), were fitted to the experimental data to obtain the activation energy (Ea) and the pre-exponential factor (A0) of the reaction kinetics. The Coats–Redfern (CR) model equation was fitted with the help of master plot (Criado’s) to identify the most convenient reaction mechanism for this system. Ea’s values were determined by the application of the five aforementioned models and were found to possess an average value of 212 kJ mol−1. The mechanism of PET pyrolysis reaction was best described by first-order reaction kinetics; this was confirmed by the compensation. Further thermodynamic parameter analysis indicated that the reaction was endothermic in nature.

“…Commercial plastic products such disposable water bottles made of PET, was used to obtain the MPs tested in this work (excluding the caps). The PET MPs preparation has been described in detailed in previous studies (Enyoh et al, 2022;Enyoh and Wang, 2022;. The plastic waste was first cut into small pieces using stainless-steel scissors.…”
