Waste batteries harm to the environment has been well known to the general public. In recent years, many city schools, communities and businesses have joined the ranks of pollution prevention and control of waste batteries were, and even the kindergarten children also participated in the recovery of used batteries. However, the contrast recent State Environmental Protection Administration and other relevant departments jointly issued the “Waste Battery Pollution Prevention and Control Technology Policy,” city in the recycling of waste batteries that there are three “errors”, has come a long “detour . ”
Mistakes do not have recycling in the recovery of
No Recycling: No mercury batteries, button batteries and low-mercury batteries
Key recovery: Nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, lead-acid asus laptop battery and other rechargeable batteries discarded
Not long ago, Haishu District, a primary waste battery recycling box, the reporter discovered the concentration of the various types of scrap batteries: mercury-free batteries, button batteries and low-mercury batteries, and so on. In fact, the majority here simply do not need to waste battery recycling.
Battery of harmful substances include heavy metals and acid, alkali and other electrolyte solution. Heavy metals include mercury, cadmium, lead, nickel, zinc, mercury, cadmium, lead on the environment and human health have greater hazards, zinc, nickel in the environment more than a certain amount will also constitute a hazard to human health. Waste acid, waste alkali and other electrolytes may contaminate the soil, so soil acidification or alkalization.
To this end, the state used batteries pollution prevention technology policy states: focus on the collection of waste batteries Nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, lead-acid batteries such as rechargeable batteries and waste silver oxide button discarded disposable batteries. In the current absence of an effective recovery technique conditions, do not encourage countries to focus the collection has reached a low mercury or mercury-free scrap disposable batteries required.
It is understood that mercury-free batteries, Ningbo, the market has reached a very high level. City’s total annual sales of all kinds of asus a31-s5 battery is about 17 million, of which the Bank of the battery company’s “Deer” batteries accounted for about 70% of the total market. At present, the Bank has the full realization of the battery cell manufacturing mercury-free. And so is estimated that the city marketing of mercury-free batteries compared to 80%. In other words, Ningbo, producing most of the waste batteries do not recall.
Mistakes of two of the incineration landfill recovery
Hazard: The burning of cadmium, mercury, lead battery waste can cause serious air pollution
Reporter visited found that, at present, the city a lot of waste batteries into the municipal solid waste, with the solid waste landfill or incineration.
Waste batteries metal mercury, cadmium, arsenic and zinc in the incineration volatile, burning into the latter part of the bottom ash, some were smoke away, encountered the cold air condensing into uniform small grain tilting. Part of the metal in the furnace involved in the reaction of chlorides, sulfides, or oxides, volatile gasification more than the original metal, the final number of these substances into the bottom ash residue, so that the heavy metal content of ash increased, difficult to handle. Therefore, incineration of cadmium, mercury, lead asus a31-s6 battery waste can cause serious air pollution, heavy metals, high levels of ash accumulation can also become heavy metal pollution.
Relevant experts believe that mercury-free batteries can be used for landfills, incineration can also be carried out and will not pose a pollution of the environment.
The information from the City Sanitation Department, that I am the urban areas of about 1,200 tons of garbage produced, of which 870 tons destined for Fenglin garbage disposal incinerator burning. At present, Fenglin incineration plant is no way of sorting garbage handling, waste mixed with garbage along the battery also burned. Being burned in waste batteries, there are many there must be recovered without the recovery of hazardous batteries.
Misunderstanding of the three ring ring collection network is out of touch
Problem: the city has yet to form an effective collection of channels, receiving waste batteries is currently nowhere to go
Battery recycling has became a focus of public concern. But the battery recycling the outcome was in doubt.
Battery recycling at present purely for the public conscious environmentally friendly behavior. It can be said that the city has not yet formed an effective channel for the collection of used asus a32-a8 battery. Not to mention a lot of communities, government agencies are not yet carry out this work, the collection of waste batteries and some schools closed or no answer. Reporters recently visited a residential district also found that the district had in the collection of waste batteries, but now it no more.
Through a telephone interview, the reporter also found that the current is not responsible for the environmental protection departments to receive used batteries. Sanitation sector was unable to sort of scrap batteries, scrap batteries currently receiving nowhere to go. Fenglin is currently only enterprise-incineration plant of waste batteries will be buried in the “concrete coffin.” It can be said that the public enthusiasm for recycling of waste batteries is almost down the drain.
According to reports, used batteries are solid wastes, including spent nickel-cadmium batteries, mercury waste batteries and waste lead-acid batteries are hazardous wastes.
Experts analyze that in order to solve the problem of pollution of waste batteries, government departments must be correct guidance, from every community, schools, enterprises and institutions since the separate collection of hazardous waste batteries, and then transported to Fenglin incineration plant sanitation sector sealed landfill disposal. The only way to fundamentally eliminate the environmental pollution caused by used asus a32-m9 battery,asus a32-s5 battery,asus a32-s6 battery,asus a33-m9 battery.
