Waste battery recycling there are three major errors

Waste battery recycling there are three major errors

Batteries harmful to the environment have been well-known to the general public. In recent years, many schools in our city, community and business began to take part in prevention and treatment of waste batteries to the list of pollution, and even the kindergarten children also participated in recycling used batteries. However, recently the State Environmental Protection Administration of the control and other relevant departments jointly issued the “Waste Battery pollution control technology policy”, the city used batteries in recycling there are three “errors” has come a long “detour . ”

One need not recall errors in the recovery

No recovery: mercury-free batteries, and low mercury button cell battery

Focus on recycling: nickel cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, lead-acid batteries such as rechargeable battery waste

Not long ago, Haishu District in a primary recovery of used batteries in the box, the reporter found here focus on the various types of batteries: mercury-free batteries, button batteries, as well as low-mercury batteries, and so on. In fact, the majority here simply is no need to waste battery recycling.

Battery of harmful substances including heavy metals and acid, alkali, such as electrolyte solution. Heavy metals including mercury, cadmium, lead, nickel, zinc, mercury, cadmium, lead on the environment and human health against the larger, zinc, nickel in the environment more than a certain amount will also constitute a hazard to human health. Waste acid, waste alkali, such as the electrolyte may be contaminated soil, so soil acidification or alkalization.

Therefore, the state pollution control waste battery technology policy: focus on the collection of waste batteries are nickel-cadmium batteries, nickel hydrogen batteries, lithium-ion batteries, lead-acid batteries can be discarded, such as rechargeable batteries and silver oxide button, such as disposable battery waste. Recovery in the current lack of effective technical conditions, not to encourage countries to focus the collection has reached a low mercury or mercury-free disposable battery waste requirements.

It is understood that the mercury-free batteries, Ningbo, the market has already reached a fairly high level. Various types of batteries in our city’s annual sales total about 17 million, of which the Bank of the battery company’s “Shuanglu” the total battery market accounted for around 70%. At present, the Bank has the full realization of the battery cell production of mercury-free. And so is estimated that the city of mercury-free battery sales ratio was 80%. In other words, the majority of Ningbo production do not waste battery recycling.

Misunderstanding of the second burning of the landfill recovery

Against: the burning of cadmium, mercury, lead batteries can cause serious air pollution

Found in the visiting reporter, at present, the city spent a lot of the battery into the municipal solid waste mixed with the solid waste landfill or incineration.

Scrap metal batteries mercury, cadmium, arsenic and zinc in the incineration volatile, burning into the latter part of bottom ash, and some were taken away by flue gas, condensation of cold air to become homogeneous when small flakes. Metal parts furnace to participate in the reaction of chloride, sulfide or oxide, the metal more easily than the original volatile gasification, and more of these substances into the final remnants of bottom ash to the heavy metal content of ash increased, it is difficult to deal with. Therefore, the incineration of cadmium, mercury, lead batteries can cause serious air pollution, the high level of heavy metal enrichment of the ash can also be sources of heavy metals.

Relevant experts believe that mercury-free batteries can be used for landfill treatment, incineration can also be carried out and will not impact on the environment.

City Sanitation Department from information that I urban solid waste production of about 1200 tons, of which 870 tons of burning to Fenglin. At present, Fenglin no way of sorting their refuse for handling solid waste mixed with waste batteries will then burned. Incineration of waste in the cell, there is no lack of recovery and not have to be harmful to the battery recall.

Errors of three network elements are out of line recycling

Question: The city has not collected to form an effective channel for receiving the waste batteries at present nowhere else to go

It had become a focus of public concern. However, the effect doubtful.

At present, members of the public for purely environmental conscious behavior. It can be said that the city has yet to form a well-established channels for the collection of used batteries. Not to mention a number of communities and units has not carried out this work, some schools and even the collection of waste battery collection nobody answered. This reporter recently visited a residential district in also found that the district was in the collection of waste batteries, but there are not a.

Through a telephone interview, the reporter also found that there are currently receiving is not responsible for the environmental protection department of waste batteries. Sanitation sector can not be sorted waste batteries, the battery is currently receiving the waste can not go anywhere. Fenglin enterprises receive only batteries, will be buried in the “cement coffin.” It can be said that public enthusiasm for recycling of waste batteries is almost down the drain.

It was learned that a solid waste batteries, including nickel-cadmium battery waste, waste mercury-containing batteries and waste lead-acid batteries are hazardous waste.

Analysis of relevant experts in order to tackle the pollution problems of waste batteries, government departments must be correct guidance, from each community, schools, enterprises and institutions to start, the separate collection of hazardous waste batteries, and then transported through the sanitation department to Fenglin landfill to deal with seal. The only way to eliminate waste from the environmental pollution caused by batteries.
