Electronic Waste or E-Waste


Recycling of E-Waste takes place in three major steps which are depicted here.
1. Detoxication
To ensure safe disposal or recycle of E-Waste, detoxication process takes place for the electronic materials. Detoxication is the process of removing critical components from the electronic waste in order to avoid contamination with toxic substances during the downstream processes. Critical components include lead glass from CRT screens, CFC gases from refrigerators, light bulbs and batteries.

2. Shredding
In the next step electronic materials are broken into pieces to obtain concentrates of recyclable materials in a dedicated fraction and also to further separate hazardous materials. The mechanical processing plants where shredding takes place includes shredders, crushing units, magnetic and eddy current and air-separators. The emitted gases are filtered and residues are treated to minimize environmental impact.

3. Refining
The third step of e-waste recycling is refining of the shredded materials to obtain reusable components. Refining of resources in e-waste is possible and the technical solutions exist to get back raw with minimal environmental impact. Most of the components need to be refined or conditioned before they can be sold as secondary raw materials or to be disposed of in a final disposal site.

i think recycling is better

i think recycling is better option for the e-waste and we can earn a lot of money from this also save our  environment

i also got a better option to

i also got a better option to overcome the e-waste to recycle the electronic waste in a secured manner and it free us from many problems facing from the e-waste still trying to change it

 

e-waste we can recycle but we

e-waste we can recycle but we need to invest huge cost so most of the people are use to destroy the wasted electronics. so we have to estimte the things.
