Cover the terminals of discarded batteries and accumulators with adhesive tape before leaving them in the collection container. The risk of fire is easy to minimise by covering the terminals of all batteries and accumulators with adhesive tape as soon as they are removed from their device. See more detailed safety instructions here.
By taking your batteries and accumulators to a collection point you ensure that the raw materials contained in them stay in circulation on the material market. Every year, more than a million kilograms of batteries and small accumulators are delivered from collection points to be recycled at the Akkuser Oy processing plant in Nivala. At the plant, battery and accumulator types are sorted into different fractions so that the raw materials contained in them, such as nickel, iron and cobalt, can be separated and utilised as well as possible. In the near future, the zinc and manganese contained in Allies, i.e. alkaline batteries, can probably be refined in Finland into trace elements used in fertilisers.
Today, batteries and accumulators contain few ingredients that are harmful to your health or the environment. Cadmium and mercury, which were previously used in the manufacturing of batteries and accumulators, are now rare, as their use has been restricted through legislation.
