Decades ago, the Germans also discarded the waste battery directly in the ordinary garbage bin. Many people do not know that the battery contains lead, cadmium, mercury, etc. harmful metal elements.

Today, Germany already has a relatively mature battery recycling system. According to the data released by the German "Battery Common Recycling System Foundation", the recycling rate of the national battery has gradually rising from 39% in 2002 to 44% in 2012. The Foundation pointed out that on the one hand, the recovery rate of the whole society is not high, not enough 50%; on the other hand, the recycled battery, its material reuse rate is almost 100%.

In guiding the German domestic battery recycling procedure, it is important to have a number of regulations issued by the European Union in 1991, as well as the "battery law" that Germany has entered into force in 2009. According to these laws, merchants for selling batteries in Germany must also establish battery recovery points. The battery recovery box in Germany Supermarket is placed in the requirements of the "Battery Law".

Waste batteries in the recipient box must be cleared at least once a week. These batteries will be transferred to the recycling factory. Divided into a binary recycling system in the German battery recycling system, the port of Northern Northern is a critical node.

The city concentrated on multiple battery recycling companies. These companies claim to have advanced technology, whether they are sorting speed, or sorting accuracy, is the forefront. These companies in port of Bremen have digested tens of thousands of tons of waste batteries; while Germany's battery recovery, totaling 155,000 tons (2010 data).

The automatic sorting device determines the ingredients inside the battery by X-ray, and sorting different batteries into different containers. Each device can sort 40 batteries per second. Sorted battery will be further disassembled.

Taking nickel-cadmium batteries as an example: wherein cadmium elements will be extracted by distillation, and is used to produce new nickel-cadmium batteries; and the extracted iron and nickel are used to produce stainless steel. Some rechargeable batteries, which will have very vulnerable hydrogen in the cathode. When the factory is dismantled, it will be particularly careful to prevent explosive accidents; refined hydrogen, usually used to produce stainless steel.

The lead-acid battery will be melted by high temperature to extract the lead. These lead will be used to produce new lead-acid batteries. It is worth mentioning that due to the lead-acid battery contains a lead element that is particularly large to the environment, the "battery method" provides that when the customer purchases the new lead-acid battery, the old battery must be exchanged at the same time, otherwise it must be paid 7.

5 Euro deposit. It is precisely because of this provision, the German lead-acid battery recovery is almost 100%. Widely used disposable dry battery to distinguish the year of production.

Although the alkaline batteries produced today do not contain a particularly harmful component, in the dry battery produced before 2001, it will still contain mercury. These mercury-containing dry batteries are still only concentrated, and there is no further treatment, prevent mercury volatilization from entering the atmosphere. Relatively harmless alkaline dry batteries, zinc, manganese, and iron will be refined.

For ordinary German people, when the battery is dropped, do not pay special attention to the battery type - automatic sorting device can be identified by X-rays. However, the battery-joint recycling system foundation still recommends that the people should remove the battery from the electrical appliance, then discard the recovery box. Otherwise, the speed and accuracy of the automatic sorting device will be affected, and the factory workload is added.
