Electric cars are not environmentally friendly lead-acid battery recycling into big environmental problems – electric cars, lead acid batteries – Electrical Industry
"Used batteries every year there are as many as 100 million, recycling is a big problem." Days, head of investor relations to power on the electric bicycle battery Zhi-Kun Wang Environmental protection Deeply concerned about the problem
Electric bike although you can achieve zero emissions, but it is the "heart"?? Lead-acid battery recycling system is not perfect, the environment is enormous.
Disorder recovery process CBN Zhi-Kun Wang told reporters that China's current holdings for the electric car is about 68 million, the annual growth rate for the 20 million, so the electric car in 2010 estimated that nearly 90 million total. 12 kg per vehicle with up to 16 kg of batteries, this battery life is only a year or so, which country will produce 1.08 million tons annually to 144 million tons of waste lead-acid batteries.
Electric car is not only environmentally friendly, energy saving, but also a natural price advantage. Shanghai Xinzha 1 Home Appliances EMU Sell People in the Department of CBN's recommendation: "The day you pay one dollar charge fee, will be able to make electric cars ran 50 km; Car Fuel expenditure is that it's three to four times. "
However, this lead content of more than 50% of lead acid batteries to be state as "hazardous waste", the electric car sales, maintenance, retail outlet will use the "TM" way to do recovery.
"Present in the Shanghai area of about 2.5 million electric car, recycled 2 million tons, but most of the recycling business are small traders are doing." Manufactured in Shanghai Secondary Lead Smelter color wheel (the "the flywheel plant") is responsible for human Guxiu Feng told reporters, these small retailers to used batteries sold in Shandong, Anhui and other places in the lead smelter to make profits.
Another factory flywheel technology official told CBN reporter, in lead-acid battery waste collection, disposal, etc. of the enterprise should have qualifications, small traders, not the regular lead smelter certainly did not.
"Also, some vendors selling process to reduce transport weight, the sulfuric acid directly down in urban and rural junctions, are polluting the environment."
Addition to recycling is not in place, the internal decomposition of waste batteries, smelting process is not standardized, seriously affect the environment. Lead battery scrap, PVC housing, waste acid, etc., have to do the whole crushing, sorting. Flywheel plant has more than 10 million yuan to buy the equipment to implement this step.
Smelting non-standard decomposition Weak technical capacity of small smelters due to limited funds, using artificial decomposition, lead and Other Pollutants are prone to leaks.
Smelting areas, the regular steam plant is done and should lead dust, secondary smelting, but also to do with a lot of lead residue burial, "a ton of landfill waste we landfill to pay 2,300 yuan to the cost. "Flywheel technology for factory who said," and started a small refinery at night, do not do more outside of direct emissions, resulting in a large number of harmful gases and waste. "
Zhi-Kun Wang said that due to annual growth of electric cars soon, the company realized that the battery recycling is an important issue, day to power in June this year, has invested 200 million yuan building a professional to do battery recycling plant, expected to be completed in 2012 , will be able to recover 150,000 tons of used batteries.
Hydrogen Shanghai climbing industry Energy Shi Tao, assistant general manager of the company, said a provision in Europe, the battery and electric car manufacturer has the responsibility to focus on recovery, so the European price of lead-acid electric bicycle up to 400 euros to 1,000 euros, compared to China, your 2 4 times, "sell a dollar of the battery, enterprises have to pay 2 yuan for environmental control costs."
The Chinese government is also to do more to reduce waste batteries and the various environmental problems.
2007, the National Development and Reform Commission issued the "Lead and Zinc Industry access" to further improve the access threshold, stop the blind investment and low-level redundant construction, the State Environmental Protection Department also led the preparation of the "waste lead acid battery collection and disposal of pollution control technology specification (draft) "and" Waste Lead-acid battery recycling industry clean production standard (draft) ", on the scrap battery recycling, handling every aspect, there are stringent requirements.
Shi Tao said the hazardous waste?? Lead-acid battery recycling in theory, should form a "closed loop" system that the cell cycle route is vendor? Buyers? Seller (or meet the qualifications of Secondary Lead) factory, the future need to do more to all parties.
