Recycling Process for the Management of E-Waste from Colour Picture Tubes of TV in Manufacturing Building Materials

Abstract:

Article Preview

E-waste released from Television colour picture tube manufacturing process is hazardous in nature and its worldwide disposal has become major concern to safe guard the environment and ecology. The solid wastes generated from the picture tube manufacturing process contain significant quantity of compounds of lead, nickel, cobolt, iron etc. The presence of toxic substances and their characteristic nature made these wastes hazardous and pose serious problems in their disposal resulting in major environmental concerns. In the present study an attempt has been made to develop a new cost effective process for immobilizing and recycling e-waste released from electronic industry in developing non-hazardous building material using additives and binders. Detoxification /immobilization of e-waste was achieved in making composite products using cement and sand as additives through solidification/stabilization process. Further strength and stability of solidified composite products was achieved through curing process. The quality and suitability of the S/S cured composite products were tested and assessed for their Engineering properties (compressive strength, water absorption, density), Toxicity leachate characteristics, Mineralogical studies, Morphological studies for their use in engineering applications, application as construction materials like bricks, blocks, aggregates and confirmed their environmental significance.
