China – World’s dumping ground for Electronic Waste (CNN)



http://edition.cnn.com/2013/05/30/world/asia/china-electronic-waste-e-waste/

Guiyu, China (CNN) — Did you ever wonder what happens to your old laptop or cellphone when you throw it away?

Chances are some of your old electronic junk will end up in China.

On seemingly every street, laborers sit on the pavement outside workshops ripping out the guts of household appliances with hammers and drills. The roads in Guiyu are lined with bundles of plastic, wires, cables and other garbage. Different components are separated based on their value and potential for re-sale. On one street sits a pile of green and gold circuit boards. On another, the metal cases of desktop computers.

At times, it looks like workers are reaping some giant plastic harvest, especially when women stand on roadsides raking ankle-deep “fields” of plastic chips.

In one workshop, men sliced open sacks of these plastic chips, which they then poured into large vats of fluid. They then used shovels and their bare hands to stir this synthetic stew.

“We sell this plastic to Foxconn,” one of the workers said, referring to a Taiwanese company that manufactures products for many global electronics companies, including Apple, Dell and Hewlett-Packard.

According to a recent United Nations report, “China now appears to be the largest e-waste dumping site in the world.”

E-waste, or electronic waste, consists of everything from scrapped TVs, refrigerators and air conditioners to that old desktop computer that may be collecting dust in your closet.

Many of these gadgets were initially manufactured in China. Through a strange twist of global economics, much of this electronic junk returns to China to die.

Dealing with Printed Circuit Board\Electronic waste the nanotech way

PCB Boards can be pulverized to nanoparticles to recoup valuable metals, polymers and oxides, affirms latest research.

PCB Boards are best recycled by pulverizing them into nanosized particles to simply restore significant constituents like polymers, oxides and valuable metals, declare Indian specialists.

The fresh method, explained in a scientific study publicized in Materials Today in March, is scalable and environment-friendly, claimed professionals from the Indian Institute of Science (IISc), Bangalore, and the Rice University in Houston, US.

In the research study, the professionals followed the rule that ultra-low temps make materials fragile and are very easy to pulverise and separate.

They placed a PCB Board in a rotating cylinder with temps brought down to minus 119 degrees Celsius before crashing it with steel balls to destroy it into nanoparticles which were then spread in water.

The nanoparticles could be put to diverse uses, the professionals said. They could be added to polymer composites improving them, utilized in 3D printing or in the manufacturing of polymer powder-based paints.

Metallic nanoparticles could be re-cycled after purification by widely recognized approaches.

“With some initial sorting, the method is able to handle the majority of PCB Boards, says Kamanio Chattopadhyay, research guide, professor at IISc and an author of the study.

Though the technology is still in the lab stage, the research team is already cooperating with an industry to confirm its scalability and effectiveness.

The innovative method, revealed in a scientific study published in Materials Today in March, is scalable and eco-friendly, said specialists from the Indian Institute of Science (IISc), Bangalore, and the Rice University in Houston, US.

In the research study, the specialists adopted the rule that ultra-low temps make materials fragile and are easy to pulverise and separate.

They put a Printed Circuit Board in a rotating cylinder with temps brought down to – 119 degrees Celsius before crashing it with steel balls to destroy it into nanoparticles which were then dispersed in water.

The nanoparticles could be put to varied uses, the specialists said. They could be added to polymer composites strengthening them, used in 3D printing or in the producing of polymer powder-based paints.

Metallic nanoparticles could be re-cycled after processing by well-known methods.

“With some early sorting, the method can handle nearly all Printed Circuit Boards, says Kamanio Chattopadhyay, research guide, professor at IISc and an author of the study.

Even if the technology is still in the laboratory phase, the research team is now cooperating with an industry to demonstrate its scalability and effectiveness.

E Waste Recycling



These films can now be viewed in a higher resolution at http://www.youtube.com/watch?v=Qa6oNloEmgo

The companies Müller Guttenbrunn, Metran and MBA Polymers jointly work on the treatment of E-Waste. This films shows the techniques used to process these e-wastes with the following steps:
1. De-Pollution using a patented smasher, 2. Shreddering in campaigns for only E-Waste, 3. Ferrous metals separations, 4. Non Ferrous Metals separations and these non ferrous metals and printed circuit boards go to smelters and 5. the plastics rich fraction is pre-processed and subsequently recycled into tech plastics that can be re-used in durable products.

Utilizing Circuit Card the nanotech way

PCBs can be pulverised to nanoparticles to recuperate valuable metals, polymers and oxides, affirms latest study.

PCBs are best recycled by pulverizing them into nanosized particles to successfully get back beneficial ingredients such as polymers, oxides and valuable metals, suggest Indian professionals.

The fresh method, detailed in a scientific study publicized in Materials Today in March, is scalable and eco-friendly, mentioned researchers from the Indian Institute of Science (IISc), Bangalore, and the Rice University in Houston, US.

In the scientific study, the researchers adopted the principle that ultra-low temps make materials fragile and are all to easy to pulverise and separate.

They put a PCB in a rotating cylinder with temps brought down to minus 119 degrees Celsius before bombarding it with steel balls to destroy it into nanoparticles which were then spread in H2o.

The nanoparticles could be put to many uses, the researchers said. They could be added to polymer composites strengthening them, employed in 3D printing or in the manufacturing of polymer powder-based paints.

Metallic nanoparticles can be reused after purification by widely known approaches.

“With some original sorting, the method can handle nearly all PCBs, says Kamanio Chattopadhyay, research guide, professor at IISc and an author of the study.

Though the technology is still in the laboratory phase, the research team is now working with an industry to exhibit its scalability and usefulness.
