With the growing consumption of electronic devices, there is growing accumulation of e-waste which are toxic to the environment and health. How can we address such an issue, what efficient recycling methods exist?
For your information, Brazilian Association of Technical Standards (ABNT) presented in São Paulo the Technical Standard ABNT NBR 16156:2013 - Electrical and electronic equipment waste - Requirements for reverse manufacturing activity. The event was a partnership of the Center for Information Technology Renato Archer (CTI), a unit of the Ministry of Science, Technology and Innovation (MCTI) engaged in research and development in information technology.
The new standard, prepared by the ABNT Study Commission for Environmental Standards for Electrical and Electronic products and systems of Brazilian Electricity Committee (ABNT/CB-03), establishes requirements for environmental protection and control of health and safety risks at work during reverse manufacturing electronics waste activity.
About 60 national organizations participated in NBR preparation, including recyclers, manufacturers, associations, universities and research centers.
Thus, recyclers and other organizations engaged in reverse manufacturing of electronics can implement a management system that includes, among other things, actions taken to eliminate negative environmental and health and safety at work impacts related to hazardous waste, traceability of waste until its disposal, protection of manufacturer´s trademark and data stored on the product and mass balance of waste, ie, the method of comparison between the material entering the process in relation to the material that comes after the achievement of all operations.

I have been working on E-waste management in India for the past couple of years. If you are interested you may go through some of the papers written by me and my colleagues. Your comments are welcome!

The E-waste recycling has two main aspects:
1- Collecting of E-waste
2-Extracting valuable materials from E-waste
During last years lot of researches have been carried out to find best methods for E-waste recycling and their results are promising. Different efficient and economic hydrometallurgical and pyrometalurgical methods have been suggested for e-waste recycling.
However there is not an efficient program for collecting e-wastes, specially in developing countries. I believe that more researches should be done in e-waste management and collection. Without an efficient system for collection of E-waste it would be impossible to recycle them.
