Development of Recycling Technology of Wastes for Electronic Products and Components

Abstract

One is a material recycling technology for thermosetting plastics composites such as printed wired boards (PWBs) and molding resins for IC packages, which are the main industrial plastics wastes for electronic components and used to be difficult to recycle.
The other is a novel technology for the treatment of fluorine waste water in order to reduce sludge volume. This technology utilizes the dependence of the solubility and fluorine adsorption characteristics of Al(OH)₃ gel on pH, and Al(OH)₃ is used repeatedly as fluorine adsorber.
