“Please put batteries into the trash and stop into the battery recycling box.” Chongqing Municipal Solid Waste Treatment Center yesterday to tell the public: we have stopped recycling batteries.
It is reported that in September last year, the Chongqing Municipal Solid Waste Center for the first time in the city’s recycling network to establish batteries, dry batteries more than 100 recycling bins located in the main city streets, and now these bins has been basically shut down.
The relevant person in charge, “since September last year, the city has recovered about 20 tons of dry-cell batteries, far less than we originally estimated. If the original plan to crush decomposition batteries, carbon rods and copper extraction apparatus, the high cost of , big loss. So these batteries are hazardous wastes are dumped at the Tongliang interchange in the city to wait for hazardous waste landfill after the completion of treatment. the beginning of this year the country also issued a document request, do not promote the recovery of low-mercury batteries, so we stopped recycling . ”
However, there are still members of the public dry-cell batteries, one after another to the Solid Waste Center. Position of the person in charge said that “many people have to treat dry-cell batteries have the environmental awareness of the simple, if they sent, we will not refuse to still be recovered.” “But science has confirmed that the mercury content of batteries which are fewer and fewer of its spread in the garbage heap of discarded and will not cause great damage to the environment. If the dry-cell batteries together buried in the land below, but the existence of environmental problems. ”
Shanghai is no longer the majority of one-time battery to encourage the recovery of
Since the mercury-free batteries can be expanded, the country has been not to encourage the collection of one-time focus on mercury-free batteries, the public collection of waste batteries while environmental protection is the delivery of behavior, still there are some errors. The reporter learned from Shanghai Waste Management Department that will cause pollution of the cell phone battery has become the focus of recovery.
Municipal waste management Department deputy chief, said from Shanghai in May 1998 started work, now has 6,000 collection points. Accumulated to the present, the total recovery of more than 302 tons had reached only 75.54 tons alone in 2003.
It is understood that the market is now more than a one-time low mercury batteries, mercury-based Environmental Protection Agency issued the “Waste Battery pollution control technology policy” that, in the current lack of effective re-use under the conditions of technology, not to encourage focus on the collection of countries have reached a low mercury or mercury-free disposable battery waste requirements. Focus on the current recycling nickel cadmium, nickel hydrogen, lithium ion rechargeable batteries and silver oxide batteries, such as one-off button.
Battery recycling no value
Is located in Anting harmful garbage sorting station director of the Tang and Sheng said a tonne of batteries to deal with the cost of 2250 yuan, but such a deal with landfill curing only, no recycling value, and more batteries into sorting plant will only increase the processing cost.
With regard to the recovery of public misunderstanding,Qi said that although the majority of the value of the battery has not recovered, we will increase the processing cost, but as long as there is battery sent, they are still responsible for recycling, storage. Because of the popularity of the concept of environmental protection itself must change with the times and the corresponding changes. The city to pay attention to environmental protection also includes a white garbage disposal, recycling paper, etc., the most critical in the recovery of batteries concept formed the basis of environmental protection, continue to protect the public’s environmental enthusiasm to encourage the public to the environmental protection acts.
Mobile phone battery pollutants into idle
Worthy of attention is the mobile phone battery has become the focus of recovery. Once-for-mobile phone, the old battery is left idle or discarded with the garbage. And mobile phone batteries, may contain much more gold, mercury, lead, cadmium and other heavy metals, if not addressed on the discarded directly in soil and water pollution, and pollutants enter the body if the food will be a significant health hazard.
It is understood that in 2003 China’s mobile phone users over 300 million. Shanghai Communication Industry Association of the manufacturing sector is Jiang Yong, deputy director of introduction, in 2003 Shanghai’s mobile phone output was 19,675,500, 18,925,900 sales. To a cell phone with two batteries, the only formal Shanghai last year, mobile phone manufacturers has increased by 37,851,800 battery.
Investigation that, in some second-hand mobile phone market, all kinds of brand mobile phone battery models usually offer only 25 million, but these batteries are in use for more than half a year later it is difficult to maintain the normal use, the pollutants become idle.
The original battery in the main ingredient is mercury pollution that the mercury. Mercury will lead to nephrotic syndrome, diseases such as neurasthenia, mercury will exist in the food chain in the long-term, continuous pollution. In China, from 2001 to the phased implementation of the battery limit of mercury content. First of all, low-mercury, mercury-free ultimate goal. Mercury-free battery of the meaning of the mercury content in batteries is less than 0.001% by weight. 2005 ban on mercury content in the domestic product is larger than this standard alkaline manganese batteries; to the 2006 ban on domestic distribution is larger than this standard mercury in alkaline manganese dioxide batteries.
