Microwave Absorption Performace of E-Waste/Cobalt-Based Mixtures

Electronic-waste (E-waste) is gaining attention as a significant concern in terms of management and recycling. The concept of utilizing e-waste in shielding applications as a microwave absorber not only stands as an innovative approach but also contributes to the development of a cost-effective solution. This paper introduces the development of ball-milled e-waste and cobalt based mixtures for microwave absorption. The study highlights a significant achievement, particularly with 50 wt.% cobalt in e-waste at a 2 mm thickness, showing a broad absorption bandwidth from 11 to 18 GHz. This innovative technique holds potential for the development of cost-effective microwave absorption materials, contributing to practical applications and advancements in technology.
