Fieldwork: E-waste

Posted: April 26th, 2010 | Author: | Filed under: waste industries | Tags: | No Comments »

On 9th April 2010, the Urban-Media Networks team carried out the second fieldwork focusing on e-waste management in Ningbo. We visited Tianyi Digital Plaza, EGO Digital Plaza and South Gate Old Product Market.

The second-hand staffs are not equal as e-waste which actually is the next process of second-hand electronic products. Just as one staff we interviewed said, the useless parts of the second electronic products are regarded as e-waste and sold to people from Guangdong and Taizhou. What’s more, there is another channel to collect e-waste, which is from the junk men in the resident areas. If people prefer throwing the useless electronic product just for convenience instead of selling them to others, then it is necessary for people to have an awareness of categorizing rubbish, or it will not only pollute the natural environment, but also be a kind of waste of resources.


Some Notes About E-waste

It is estimated that E-wastes are generated 20-50 million tonnes per year in the world (Greenpeace 2008). Nowadays, Because of the high tech, the life cycle of electronic equipment is shorter than before. The products update quickly. UNEP-Vital-Graphic (2004) reports that the computers have an average life span of only 2 years in developed countries. There are many problems in recycling and disposal of E-waste. Open burning of E-wastes is toxic because of hazardous and materials such as heavy metals and PVC which are harmful for environmental, animals and human health (Greenpeace 2008). The contamination of wastes has an impact on the surrounding soils. In China, Dumping and the open burning sites are still common.

As the research conducted by Greenpeace, the electronics products contain lead, Cadmium (can result in damage to the kidneys and bone toxicity), Antimony, Phthalates, PCBs, etc. UNEP-Vital-Graphics points out that there are about 23% plastic, 32% ferrous metals, 18% non-ferrous metals, 12% electronic boards and 15% glass in a computer. However, only about 50% of the computer can be recycled.

The regulation is necessary for controlling the environmental pollution. During designing and manufacturing, the use of hazardous chemicals should be avoided. Furthermore, although the imports of E-waste is banned, there are still a large amount of illegal E-wastes enter into China.
