Pyrolysis process is classified into three main categories according to the amount of heat energy needed to destruct plastic connections. There is high temperature, medium temperature, and low temperature-based media. Medium and high temperatures are based on the range of temperatures used to destroy...
[86]. Several chemical recycling techniques like pyrolysis, solvolysis, gasification, and dissolution/precipitation further enhanced by chemical procedures such as microwave heating, plasma reactors, or the usage of compound chemicals and supercritical fluids can be particularly helpful for the chemical ...
When the FE model’s mesh size was set at 5 mm, the force solution process appeared to converge, with an average mesh mass of 0.9836, which was sufficient for analysis (Fig. 2d). The meshing diagram of the FE model for the plastic chair is presented in Fig. 2e. To realistically ...

demonstrated the feasibility of vacuum pyrolysis and mechanical processing for recycling PCBs. The glass fiber could be obtained by calcinations in a muffle furnace at 600°C for 10 min. The main components of the nonmetal materials of waste PCBs are glass fibers and thermoset resin matrix [41]...
2.1.1. Thermal pyrolysis Thermal pyrolysis is a common pyrolysis type, which involves the upgrade of waste plastic upon heat treatment and under an inert atmosphere. This process involves heat application of the feedstock, in which the reaction temperatures range from 400 to 600 °C [47]. The...
