EDITORIAL

Production of electronic equipment is the world'sfastest growing industry. The fast growth coupledwith the rapid technological changes, low costand fast obsolescence of electronic equipmenthave led to generation of large volume of waste.Electronic waste is considered to be the fastestgrowing waste stream around the globe. E-wasteencompasses wide range of electrical andelectronic devices such as computers, mobilephones, audio & video systems, includinghousehold appliances such as refrigerators, airconditioners etc. Basically e-waste containsmaterials such as metals, glass and plastics. Inaddition to the valuable and precious metals suchas Cu, Sn, Al, Ag, Au etc. it contains many toxicsubstances which are hazardous to environmentand human health. Though efforts have been putin on recycling of e-waste, the problem is yet tobe resolved fully. There is a need to take a totalisticapproach towards finding a sustainable solutionto this challenging problem. Besides developingeco-friendly and cost effective technology foroptimum separation of materials, strategies areto be worked out for systematic disposal andcollection of e-waste and implementation ofrecycling process. In order to address the variousissues related to e-wastes a National Seminar onElectronic Waste (NASEW-10) is being organizedduring January 21-22, 2010 by NationalMetallurgical Laboratory, Jamshedpur (CSIR)with support from Department of InformationTechnology (DIT), Government of India.

The present volume consists of papers underdeliberation in NASEW-10 covering differentaspects of electronic waste. The topics coveredinclude - E-waste Policy & Regulation; EffectiveManagement of E-waste; E-Waste Recycling &Development Needs; Recovery of Plastics andGlass from E-waste; Recovery and Reuse ofMetals from E-waste and E-Waste & Preventionof Environment Pollution.

We are thankful to Dr. Sukomal Ghosh, ActingDirector, NML for his encouragements inorganizing the seminar and bringing out theproceedings volume. We are thankful to all theauthors for contributing papers for the seminar.Thanks are also due to all the sponsors for theirsupport towards success of the seminar andpublication of the volume.
