TMS 2009: Green Materials and Processes for Managing Electronic Waste
Date: Sunday, February 15

Waste electric and electronic equipment (WEEE), or electronic waste (e-waste), has been considered by government and the public due to its hazardous material content. E-waste consists of a wide variety of equipment, including washing machines, televisions, computers, mobile telephones, electrical tools, medical equipment, control instruments, etc. Many developed countries now require these items be reused, recycled, and recovered e-waste rather than be disposed of in landfills.


About this Workshop

From the point of material composition, electronic waste can be defined as a mixture of various metals, particularly copper, aluminum and steel, attached to, covered with, or mixed with various types of plastics and ceramics. Though in small mass fraction, for cell phones, calculators and printed circuit board scraps, the precious metals, such as Au, Ag and platinum group metals, make up more than 70 percent of the value; for TV boards and DVD players, the metals contribute to about 40 percent. The major economic driver for recycling of electronic waste in industry is from the recovery of precious metals.

Currently, recycling of e-waste can be divided into three major steps:

  1. Disassembly — selective disassembly, targeting hazardous or valuable components for special treatment, is an indispensable process in recycling of e-waste.
  2. Upgrading — this involves using mechanical processing and/or metallurgical processing to upgrade desirable materials content, i.e., preparing materials for the refining process, such as grinding plastics into powders.
  3. Refining — in the last step, recovered materials are retreated or purified by using metallurgical processing so as to be acceptable for their original use.

Attendees will learn about the following aspects of e-waste:

  • Mechanical recycling
  • Recycling of plastics
  • Recovery of metals
  • Hydrometallurgical recycling (leaching)
  • Combustion or pyrolysis
  • Life cycle and economic analysis for recycling
