E WASTE


1.         I earlier attempted to discuss on this subject when I wrote on Guiyu few weeks back.But I had not written anything on what India has been doing on the subject matter except for some one liner remark at the end.But that was because I did not find anything of weight anywhere. Recently I found some useful content at http://india.ewasteguide.info/

2.         This site mentions about  K.G.NANDINI ENTERPRISES (KGN) based in Bangalore which is India's first full integrated electronic waste recycling plant. The Plant is located in Bidadi, next to Wonderla and has a capacity of 1.0 ton per hour. KGN has taken the license (CFE & CFO) from KSPCB for a capacity of 7200 MT/annum and does accept all kind of ewaste (printed circuit boards, computers, electrical cables, electrical transformers, small house hold appliances etc.).

 

3.         In a first step hazardous wastes or elements are removed manually. Loading point of the plant is the shredder. The reduced material is then passing a magnet, FE parts are removed. Afterwards the material enters the delamination mill, the heart of the process. Very high forces affect the composite materials and are thereby reduced and delaminated. The material is pneumatically transported from the mill to a cyclone, is discharged and conveyed to a screening machine. The classified material is transferred to a battery of separators; non ferrous metals are separated from plastics. All process steps are connected by conveyors, are automated and controlled by visualization. A central filter system, which is equipped with explosion and fire safety measures, de-dust the entire process. The equipment reflects the state-of-the-art technology had has been developed and provided by swissRTec AG from Switzerland.
