In order to strengthen the management of used battery, the German implementation of the management of waste battery recycling new requirements. Provision requires that consumers will use the end of the dry battery, button battery and other types of battery to the store or recycling waste recycling, waste recycling shops and unconditional acceptance of used battery, and transferred to manufacturers for recycling Lenovo 3000 N500 battery.
It is estimated that worldwide there are 32 billion each year is discarded used battery, only Germany is necessary to consume an average of 10 battery per year, totaling about 30,000 tons, a large number of discarded used battery on the soil damage to the environment are serious. German environmental sector for the new regulations could put an end to throw used battery of the phenomenon, is still not sure, because before, waste recycling and recovery of manufacturers is generally contain cadmium, mercury toxic chemical constituents of cells, and 90% of the ordinary zinc-carbon Lenovo Ideapad Y430 battery and aluminum-magnesium battery are used as a solid waste landfill or incineration.
According to the German Environment Ministry statistics, Germany’s annual recovery of the toxicity of nickel-cadmium battery with only 1 / 3, and 2 / 3 of the battery used as a municipal solid waste each year of mercury into the environment, about 8 tons, 400 tons of nickel, cadmium 400 t. In general, make the distinction between ordinary consumers in their lives of toxic battery or non-toxic battery and deal with them is difficult, so the new provision requires shops and assume responsibility for waste recycling. Ministry of Environment, a new way of thinking Lenovo IdeaPad Y730 battery is toxic nickel-cadmium battery and mercury battery to implement a deposit system, that consumers buy every cell contains a deposit of 15 marks, when consumers take old battery to change, the price can be deducted from the deposit.
Magdeburg peri-urban areas are being built a “wet processing” devices, where the addition to lead-acid battery, the various types of cells were dissolved in sulfuric acid, and then using ion resin extracted from the solution of various metal objects, using materials obtained in this way pure than the heat treatment method, so a higher price in the market, and the battery contains 95% of the various Lenovo ThinkPad R400 battery (14-inch wide) substances can be extracted. Wet processing can be avoided sorting areas (because the sorting is a manual operation, will increase the cost). Magdeburg annual processing capacity of this device up to 7500 tons, which means that while the cost is slightly higher than the landfill, but the precious raw materials will not be discarded, it will not pollute the environment.
German Duarte’s vacuum heat treatment developed in France but also cheaper, but that first need to sort out the waste battery, nickel-cadmium battery, used battery by heating in a vacuum, in which the rapid evaporation of mercury can be recovered, and then the remaining Lenovo ThinkPad T400 battery (14-inch wide) ingredients ground, using magnets to extract metals iron, and then extract the powder from the remaining nickel and manganese. This process one ton of waste battery costs less than 1500 marks.
