Recovering battery cells from ordinary consumers is much more difficult. These are, for example, all single cell batteries (AAAA to D), button cells and rectangular batteries. Even though the situation with recovering used batteries has been improving, only about a third of portable batteries in circulation is eventually recycled or reprocessed.
That is why the European Parliament together with the Council of the European Union issued the directive 2006/66/EC on batteries and accumulators and waste batteries and accumulators. Its aim is to help protect, maintain and improve the quality of the environment. The directive also ensures smooth functioning of the internal market by harmonising the requirements for introducing batteries and accumulators.
In order to achieve all the set environmental goals, the directive, among other things, bans certain batteries and accumulators from the market, precisely because they are difficult to recover. This applies e.g. to portable batteries and accumulators in which more than 0.002% of the weight is made up of cadmium; this includes batteries and accumulators built into devices. And that is why you can’t buy nickel-cadmium AA batteries in Member States of the EU.
Generally speaking, the directive aims to ensure that batteries are manufactured and sold on the market in a sustainable and responsible manner. They should also be energy-effective and designed for long durability. Used batteries should be properly collected and recycled, and the valuable materials that they contain should be returned to circulation and used efficiently. In order to collect used batteries successfully, end users must be informed about the importance of waste sorting, about current collection systems and their role as end users in the handling of used batteries and accumulators.
Among other things, the EU has adopted an implementing regulation for a labelling system that gives end users clearly readable information about each battery and accumulator and their content of heavy metals. In terms of manufacturer responsibility, the manufacturers of batteries and accumulators and of other products that have a built-in battery or accumulator are responsible for the waste related to the batteries and accumulators that they introduce on the market.
By 2030, the European Union wishes to achieve a 70% success rate in the collection and recycling of all portable batteries and to pass a full ban on landfilling batteries.
