People do not understand the used batteries to realize that waste energy-saving lamps also \"Henjiao Se.
Untreated discarded caused by mercury pollution, so that the \"energy saving rookie head\" halo \"is no longer pure. The key is to eliminate the \"hangover\" of energy-saving lamps: how the successful recovery of the waste of the user in the hands of light, or guide them to \"take the initiative to hand over\"? How to safely dispose of these mercury-containing \"bomblets\", rather than simply dismantling and reuse ? who should foot the bill for this expensive recovery chain \"?
Many cities there was no established energy-saving lamp recycling business recycling system set up just the start. Energy-saving lamps promotion strategy will be how to continue? Ultimate fate of the hands of the people of the waste energy-saving lamps?
\"TM\" recycling advocate environmental awareness is only the first ring in this complex chain.
The dual identity of the energy-saving and pollution. \"
Almost all energy-saving lamp packaging brief, the mercury content are casually and even did not mention. In stark contrast, energy-saving lamps of mercury pollution due to improper handling in the industry is hardly a secret.
However, in the promotional process of the energy-saving lamps, except to say that this light is very energy-saving, rarely heard it can cause mercury pollution. It is understood that if an energy-saving lamps were broken, there will be 1800 tons of water is evaporated out of the mercury pollution, that is, a energy-saving lamps contain only 5 milligrams of mercury caused by water pollution capacity of 1800 tons and its production which may be caused by environmental pollution factors into account.
It is understood that the promotion of energy-saving lamps in the countries in green lighting project occupies an important position. In March 2007, the EU proposed a complete end to the incandescent age \"before 2009, use of energy-saving lamps; Since 2007, the United States, Australia, legislation to prohibit the use of incandescent lamps, the promotion of energy-saving lamps.
Before and after 2008, called for in response to the national energy saving, many cities began to use government subsidies to promote energy-saving lamps. It is understood that the energy-saving lamps are the second generation of lighting products, compared with two hundred years of history of the first generation of traditional incandescent advantage is obvious: the same lighted 10 hours, and incandescent lamps consume one kWh, energy-saving lamp consumes only 0.16 degrees. In view of this, energy saving lamps is indeed effective energy-saving, reducing carbon dioxide emissions. Energy-saving lamps at an unprecedented rate, the rapid spread of traditional incandescent or even extinct in some districts.
Can be an issue is always the lingering, that is, the amount of mercury in energy-saving lamps. National provisions of the mercury content of energy-saving lamps is less than 10 mg, but the absence of mandatory standards for mercury content, the level of the mercury content of different manufacturers products vary greatly. According to incomplete statistics, about 2000 large-scale enterprises of the national energy-saving lamps, but because of the large size of the market access threshold is too low, the level of production varies, resulting in the uneven quality of the energy-saving lamps. The price of six yuan, energy-saving lamps, mercury content is usually about 5 mg, and only some well-known brands of lighting, mercury levels can be done for less than 3 mg or even less than 1.23 mg, or use better technology to solve, such as solid-state mercury.
Energy-saving lamps must contain some mercury, but only 0.1 mg of the power of the pollution of the environment will be big amazing. Mercury is installed in the lamp body, under normal conditions of use is safe, but if the waste thrown away, resulting in the rupture of the lamp body, mercury can evaporate at room temperature in ambient air mercury concentration in excess of a hundred times, resulting in air groundwater pollution and the city, if the mercury into the body, and bring very serious consequences. It seems that the energy-saving lamps, mercury pollution risk coefficient is much higher than the battery.
According to industry sources, if the waste energy-saving lamps without professional treatment, etc. Then a \"time bomb\", either incineration or landfill, will eventually cause pollution. At present, the national list of hazardous waste \"energy-saving lamps has been included, but the energy-saving lamps, mercury pollution has not been widely recognized. Reporter visited Harbin found that only one or two foreign energy-saving lamps brand in each box marked \"not trash\" and \"recycle\" icon, and marked with the toxic and hazardous substances or elements in the table, suggesting that \"light broken pipe or product end of life, seeking to address local environmental regulations. But there is no suggestion in the vast majority of domestic energy-saving lamps.
