Abstract

The disposal of mobile communication devices, which forms part of their life cycle, is considered in the present work. The valuable components present in various devices (mobile phones, smart phones, tablets, e-books) are noted. On that basis, the yield of basic components is plotted against the type of device. The gaseous emissions associated with the roasting of electronic waste are tabulated. Analysis of existing disposal methods permits the development of a system for the disposal of mobile communication devices based on a combination of mechanical and thermal methods. The reactor employed includes a retort that facilitates the charging of crushed components and their final discharge. The cycle for the continuous operation of two reactors is presented. By combining low-temperature pyrolysis and electrical melting, valuable products may be obtained: gold, silver, copper, and carbon black. The production of granulated fuel from such carbon is discussed. The use of a hydrodynamic scrubber minimizes the environmental impact of the system for disposal of mobile communication devices.
