Research Summary Recycling Electronic Scrap

Abstract

tAs the number of electronic products in use increases, so does the need to dispose of defective and obsolete equipment, including printed circuit boards. The utilization of mechanical processing in recycling this type of waste enables recovery of the metals and allows components to be separated for proper waste disposal. Mechanical processing allows the recovery of 80% of the metals in printed circuit boards, especially copper, which represents approximately 75% of the metallic fraction.
