Nowadays, more and more energy-saving lamps have entered the public households with the government's subsidy policy, and they are favored by consumers with the advantages of obvious energy-saving effect and long life. However, although the role of energy-saving lamps in reducing energy consumption is obvious to all, the problem of mercury pollution caused by waste energy-saving lamps is gradually exposed. It is reported that an ordinary energy-saving lamp contains about 0.5 mg of mercury. If it is not handled properly, once it breaks, it will pollute 180 tons of water.
In the past few days, the reporter found in Nanchang City that most of the citizens often throw away the waste energy-saving lamps. At present, Nanchang City has not set up a special waste energy-saving lamp recycling site, and has not established a unified recycling and reuse operation mode. In this regard, relevant experts have called for the government to vigorously promote the use of energy-saving lamps by means of financial subsidies, and should also establish a recycling system for waste energy-saving lamps to avoid the path of development and post-governance.

Last year, Jiangxi Province promoted 2.23 million energy-saving lamps
In recent years, the state has adopted financial subsidies to promote energy-efficient lighting products. Data show that in 2009, Jiangxi promoted 2.23 million energy-saving lamps. After being put into use, it is estimated that the annual electricity saving will be about 107 million kWh, the carbon dioxide emission reduction will be 107,000 tons, and the sulfur dioxide will be 0.107 million tons. In order to encourage the widespread use of energy-saving lighting products, local governments have also established promotion and management departments for energy-saving lamps. According to the staff of the Nanchang Energy Conservation Supervision Center, in 2009, the Nanchang Municipal Government formulated a double preferential policy in promoting energy-saving lamps. When citizens purchase energy-saving lamps, they can not only enjoy 50% of the state financial subsidies, but also enjoy 20%. Local subsidies. This year, Nanchang City and Jiangxi Province will continue to promote efficient lighting products in the province.
1 energy-saving lamp of mercury can contaminate 180 tons of water
What followed was a worrying issue that began to emerge. “Limited by the manufacturing process, the energy-saving lamp tube contains a certain amount of mercury.†A well-known lighting industry staff said in an interview that although the energy-saving lamp has obvious advantages over ordinary incandescent lamps, it contains mercury. It is an undeniable fact that mercury is a highly toxic chemical that is very polluting to the environment. The reporter learned that mercury is an important factor in determining the brightness of energy-saving lamps. Therefore, a small amount of mercury is used to produce energy-saving lamps. At present, the amount of mercury in energy-saving lamps on the market is about 0.5 mg/head.
Experts pointed out that when energy-saving lamps are used in daily use, mercury generally does not leak from the closed lamps, but after the energy-saving lamps are broken, mercury will evaporate. Mercury leaks into the soil and groundwater, causing soil and water pollution. It is reported that when 1 mg of mercury is infiltrated into the ground, about 360 tons of water can be contaminated. From this calculation, 0.5 mg of mercury in an energy-saving lamp can cause at least 180 tons of water to be contaminated. In Jiangxi, millions of energy-saving lamps are promoted in one year. If the waste energy-saving lamps are handled and recycled improperly, it will cause great environmental pollution.

The old energy-saving lamps were thrown away by the citizens.
How do Nanchang citizens deal with waste energy-saving lamps? The reporter interviewed a number of households in a residential area in Zizi Road, Minde Road and Xiangshan North Road in Nanchang. Most of them said that they don't know that the energy-saving lamps contain mercury. "When the energy-saving lamps are bad, they are usually thrown directly into the trash cans. They have not heard that they can't be thrown, and they have not heard of special recycling." These households said.
The reporter found that it is easy to find discarded energy-saving lamps in the trash cans of many communities. These energy-saving lamps are mixed with other household garbage, some of which have been broken.
Waste energy-saving lamps have nowhere to recycle
Has Nanchang City set up a special recycling station for used energy-saving lamps? On the 25th, the reporter visited two waste recycling stations in Nanchang with two waste energy-saving lamps, but no one wanted these energy-saving lamps that were “completely worthlessâ€.
A staff member of a waste recycling company in Nanchang told reporters that recycling waste energy-saving lamps not only has no profit, but also brings troubles in handling. Another waste recycling station staff refused directly. "We can't sell it after recycling, plus the energy-saving lamps contain mercury. This is a highly toxic chemical. We dare not touch it."
So, has the government's relevant functional departments set up such a recycling site? Subsequently, the reporter consulted the city appearance and environmental protection departments of Nanchang City. It was found that there was no special recycling site for waste energy-saving lamps, and no unified recovery and reuse operation mode was established. In addition, the reporter also learned that despite the huge sales of energy-saving lamps, Nanchang City's enterprises engaged in recycling and recycling of energy-saving lamps are still blank. The industry believes that one of the important reasons is that solid mercury is extracted from waste energy-saving lamps, and liquid mercury is used in the production of energy-saving lamps. There is a price difference between the two.
Call for experts: establish a recycling system as soon as possible
Environmental experts and environmentalists attach great importance to the environmental pollution problems that may be caused by waste energy-saving lamps.
Experts from the environmental protection department of Jiangxi Province said that in the context of the increasing use of energy-saving lamps in Jiangxi Province, how to safely recycle and dispose of used energy-saving lamps to prevent environmental pollution is a very important issue. “Intensifying the recovery, treatment and supervision of waste energy-saving lamps and controlling mercury pollution is imminent.â€
Relevant persons suggest that Jiangxi Province should formulate corresponding policies and regulations as soon as possible to clarify the recycling responsibilities of producers, sellers and users. While vigorously promoting and promoting energy-saving lamps, it is also necessary to clarify the safe handling and recycling of wastes by enterprises and management departments. The responsibility of energy-saving lamps. In addition, relevant departments should increase publicity to the general public at the same time, raise awareness of environmental protection, and allow users who use energy-saving lamps to properly dispose of used energy-saving lamps.
Membrane Switches also called membrane keypads have very widely application and also have many different using environment. For example in wet environment, in outdoor under sunshine UV and bad weather of rain, boat sailing on the sea etc. Then a waterproof and anti-UV membrane keypads are necessary for such kind of special application.
