Mathematical modelling, simulation and experimental validation of resistance heating and induction heating techniques for E-waste treatment

摘要

Over the last few decades, E-waste has become a serious concern all over the world due to the large generation, improper policies of management, inefficient techniques of recycling, adverse safety hazards etc. Different methodologies have been used for recycling of E-waste, which further generates a large amount of secondary waste in the form of solid, liquid, and gases. Improper disposal of E-waste and secondary waste adversely affects the human health and environment. Pyrolysis process, which is considered the most suitable technique for recycling of various wastes such as bio waste, plastic waste, and E-waste has been discussed in detail. In this process, E-waste is required to be heated up to 1000 degrees C for volume and weight reduction. In this study, resistance and induction heating techniques have been used for pyrolysis of E-waste. The study also focused on the mathematical modelling and validation of experimental data generated during the studies. Comparison evaluation of performance pertaining to both the heating techniques for pyrolysis of E-waste was carried out and the result shows that weight reduction of E-waste is relatively higher in case of induction heating and the same could be achieved at a faster rate and the technique was found to be more efficient as compared to resistance heating.
