Environmentally Sound Management of E Waste
Turn the old to the new, reuse or recycle
E–Waste Processing Flowchart
“Electronic Waste” may be defined as discarded computers, office electronic equipment, entertainment device electronics, mobile phones, television sets and refrigerators. This definition includes used electronics which are destined for reuse, resale, salvage, recycling, or disposal. This e-Waste has very small shelf life and very low reuse market potential. On the other hand, these items contain highly toxic heavy metals like Ni, Cd, Hg , Pb, Chrome etc. and highly carcinogen poly chlorinated biphenyls and other toxic compounds. In order to ensure environmentally safe recovery of useful products and metals and environmentally sound treatment and disposal of harmful and non useful components, GEPIL is putting up centralized E-waste processing facility as part of its TSDF – Surat and TSDF – Haryana. The facility is targeted to collect E-waste from Institutes and corporate in the northern and western India. The facility is being developed with the technical support of IRG systems.
The growth of e-waste has significant economic and social impacts. The increase of electrical and electronic products, consumption rates and higher obsolescence rate leads to higher generation of e-waste. The increasing obsolescence rate of electronic products also adds to the huge import of used electronics products. The e-waste inventory based on the obsolescence rate in India will cross 8,00,000 MT in 2012.
There are 3 main processing techniques used by GEPIL for treating e-Waste:
Specially trained staff dismantles the electrical & electronic equipment into its fundamental components. Pollutants (batteries, capacitors, mercury switches, etc) are expertly removed. Electronic components and complex assembles are then further processed in recycling plant.
Only 9% of all electronic waste is recycled in India. Perfectly good components are never put to use.
The pollutant-free assembles undergo mechanical processing. Using sophisticated dry-mechanical process technologies, iron & non-ferrous metals are recovered separately and mixed-plastic compounds are separated and sorted (three stage milling followed by magnetic and eddy current separators and density separating processes). There are mills available for producing metal-free plastic granulates for unmixed plastics.
Recovery of Precious Metals
Processing Picture Tubes Screen & funnel glass from picture tubes from VDUs and TVs are separated. Subsequently the coating containing the pollutants is removed in a dry process in a closed system. The results of the processing are re-usable glass products.
Technical facilities are essential for GEPIL and without them we would be unable to recover raw materials from recyclable materials. As we recycle more effectively than others, we carry out intensive R&D work. GEPIL has expertise in the management of wide variety of WEEE at its integrated facilities. GEPIL is in process of handling and managing e-Waste as part of its hazardous waste management facilities at…
