E waste

Editor's Notes

1. Moore’s Law: Gordon Moore, cofounder of Intel predicted that computer processor speeds would double every eighteen months. 1965 idea behind it is the main driver of legislation for recycling eWaste. Technology changes rapidly New software for computer applications such as streaming music and videos and animating presentations are not supported by older systems. But its relatively cheap to replace them with computers that can support the technology. (Click away.)
2. These materials could cause harm to the kidney, brain and nervous system function or cause cancer. According to the EPA, the most common method for human exposure to these chemicals is through their leaching into bodies of water and bioaccumulating in the animals we eat.

5. The Electronic Waste Recycling and Consumer Protection Act proposes that recycling of eWaste be promoted by offering tax credits of $8 per unit for recyclers who collect 5000 or more units and $15 per unit for consumers who bring their ewaste to be recycled. The Act also calls for ewaste to fall under a stricter category of waste than simply solid waste and eventually, once adequate collection programs exist, become unlawful to dispose of. The Act also prescribes an EPA feasibility study to review the collecting of advance recycling fees, collecting of end of life fees and the possibility of holding manufacturers responsible for the cost of recycling. After one year of enactment the EPA would also be required to assess the success of the program and the possibility of including other electronic waste streams in the Act.
6. It will be up to manufacturers to notify retailers of those electronic products on which to charge fees.   But another aspect of this law is that manufacturers can play a key role in consumer education. Where to return obsolete electronic products for recycling or disposal, how to properly handle and what toll-free phone numbers to call for help will go a long way in resolving this dilemma.
7. To our knowledge this work represents the first reported cord blood tests for 261 of the targeted chemicals, and the first reported detections of at least 209 chemicals. Scientists refer to this contamination as a person's body burden. The study found a broad array of pollutants that collectively are known to present potential risks to nearly every organ and system in the body:• Of the 287 chemicals found in newborn umbilical cord blood, 180 cause cancer in humans or animals, 217 are toxic to the brain and nervous system, and 208 cause developmental problems. The dangers of exposure to these chemicals in combination has never been studied.• We detected 287 chemicals of 413 tested (69 percent) in umbilical cord blood samples from 10 newborn babies, with a range of between 154 and 231 for each child. We found 101 chemicals in all babies tested.• Our tests targeted nine chemical classes; we detected at least half of the analyzed chemicals in each class.

10. These are two typical pollution of e-waste recycling in Guiyu. Left hand side is the process using acid to take gold and other metals from printed circuit board. They do not treat wastewater, just discharge it into rivers. Right hand side is the process removing IC tip and solders from printed circuit board, using heat. There are hundreds of such workshop in this area. Several chemicals might cause air pollution.
