SMM News: a few days ago, by the General Administration of Market Supervision, the National Standards Commission approved the issuance of an important national standard in the field of environmental protection-"waste lead-acid battery recovery technical specification." The standard stipulates the treatment methods and management measures for the collection, storage, transportation and transfer of waste lead-acid batteries, which is helpful to standardize the recovery and utilization of waste lead-acid batteries and prevent secondary pollution. At the same time, it will play an exemplary role in standardizing the overall development of the waste battery recovery industry.
Scrapped lead-acid batteries contain lead and acid, and improper disposal can cause harm to the environment and safety. One of the drafters of the standard, Yi Xiaobo, deputy director of the Shenyang Battery Research Institute and chairman of the National lead-acid Battery Standard Committee, believes that the normative recovery amount of waste lead-acid batteries in China is the prerequisite for the implementation of this standard. If the normative recovery is very low, no matter how good the standard, the effectiveness of the implementation is also limited.
Yi Xiaobo said that unlike many waste products, the reuse rate of lead in waste lead-acid batteries is extremely high, mainly to recycled lead smelters, with a recovery price of about 10,000 yuan per ton. The considerable recovery price makes the recovery rate of waste lead-acid batteries very high. Therefore, the harm of waste lead-acid battery to the environment and human body comes from collection, storage, transportation, transfer and so on. This is also the importance of the formulation of this standard-the recovery enterprise of waste lead-acid battery is the main body of this standard. As long as recycling enterprises can implement the standard, the harm of waste lead-acid battery to the environment will be greatly reduced.
According to reports, China produces about 5.5 million tons of waste lead-acid batteries every year, of which about 500000 tons are old lead-acid batteries, which can continue to be used through maintenance. The demand for raw materials of recycled lead smelters in China is about 12 million tons. Although waste lead-acid batteries are the main raw materials for recycled lead smelting, 5 million tons of waste lead-acid batteries can not meet the needs of recycled lead smelting industry.
Yi Xiaobo is generally optimistic about the implementation effect of this standard, but thinks that there is also a certain degree of difficulty. The key to the effectiveness of the implementation of the standard depends on the training effect of the relevant market subjects. At present, only about 30% of lead-acid batteries in China contain flowing sulfuric acid electrolyte, that is to say, about 70% of the electrolyte in lead-acid battery is immobile, or adsorbed in glass fiber cotton or colloidal state. If there is no serious fall or impact rupture, the electrolyte will not leak out to harm the environment, even for waste lead-acid batteries containing flowing electrolytes, because most of the batteries have strong sealing properties. And the electrolyte doesn't flow out easily. Secondly, from the normative point of view of recovery, first, the dealers and sales networks of battery production enterprises, most of them can grasp the basic requirements for the recovery of waste lead-acid batteries; Second, communication, railway, station, wharf and other users who focus on the use of lead-acid batteries will generally sell the waste lead-acid batteries directly back to the recycled lead smelter; Third, most of the qualified recycled lead smelting enterprises due to the price of waste lead-acid batteries and professional reasons, the recovery process is more standardized.
Yi Xiaobo stressed that with the implementation of the standard, battery dealers, centralized users and recycled lead smelting enterprises will be more standardized in the recovery of waste lead-acid batteries, and 60% of the recovery of waste lead-acid batteries can ensure that they are environmentally harmless. The remaining 40% come from scattered social sources such as cars, motorcycles, repair shops and so on. These subjects are basically unable to grasp the normative requirements for the recovery of waste lead-acid batteries, and it is difficult to standardize the recovery training.
Yi Xiaobo suggested that one of the solutions is for battery manufacturers to co-ordinate training, first training dealers, and then through dealers to purchase battery users and scattered social sources for training; Second, the recycled lead smelter carries on the special training to its recovery network; Third, 4S store and the corresponding brand joint training, repair shop, accessories store and waste recycling shop need to take certain measures to supervise the training and promote the implementation of the standard. Yi Xiaobo said: since the standards issued this time are recommended national standards, even battery dealers, recycled lead smelting enterprises, and centralized users of lead-acid batteries have a certain basis for the recovery of waste lead-acid batteries. But it is also difficult to regulate itself to the level of standard requirements, let alone fragmented social sources. Therefore, the publicity and training of standards is very important and urgent, and it needs to play a de facto and mandatory role through policies, regulations and other channels. Because even a small amount of lead and acid from waste batteries enter the soil and groundwater, will cause serious harm to the environment.
In addition, Yi Xiaobo stressed that waste lead-acid batteries may cause harm to the environment not only lead, but also acid. Some recycled lead smelting enterprises do not have the ability to deal with waste acid, so the recovery channel is required to pour out the acid on their own, thus causing pollution to the environment. Most of these enterprises are unqualified low-end small and medium-sized smelters, and the relevant departments should ban them through strict law enforcement.
