How many used batteries do you have at home? Do you want to know how you can help us give a new lease of life to used batteries?
Hand over used batteries to a SNRB collection point!
All batteries collected across the SNRB nationwide network undergo a thorough sorting process based on their electro–chemical properties and are then set to recycling facilities, where, after a number of highly complex technological processes, numerous metals such as lead, zinc, nickel, cadmium, and cobalt are recovered and then returned to economic circulation as reusable materials in other manufacturing processes.
A line for treatment of batteries and portable accumulators involves both providing a service of treatment and disposal of hazardous waste, and deriving regenerated products such as secondary raw materials which are returned to economic circulation.
What is sorting used batteries?
Sorting is the key stage in battery treatment. The quality of the sorting process ensures that recycling is effective. The entire technological process includes manual sorting using a conveyor belt to remove foreign bodies, and subsequent mechanical screening for recovery of pill batteries. Mechanical treatment of batteries includes breaking, magnetic separation, screen separation and quality-based separation of particles.
How are used batteries recycled?
- Batteries are recycled by means of 4 technological processes, based on individual categories:
- Pirometallurgy (alkaline and saline batteries, Li batteries, NiCd batteries, Li-Ion batteries and NiMH batteries)
- Hydrometallurgy (alkaline and saline batteries, NiCD and Li-Ion batteries)
- Distillation (pill batteries and some types of rechargeable batteries)
- Fusion (lead batteries)
The common objective for all processes is separation of metals incorporated in batteries in order to achieve highest possible purity so that such batteries can be reused in various industries.
The resulting fractions are ferrous fraction and non-ferrous fraction, black powder (a mix of zinc, carbon and manganese). Both ferrous and non-ferrous fractions are then returned to economic circulation in the steel industry and in zinc melting furnaces, whereas paper and plastic are recovered as alternative fuel in cement industry.
Recovery or a new lease of life
A tonne of alkaline batteries allows for recovery of 330 kg of zinc and zinc compounds and 240 kg of iron- and nickel-based alloy. Such metals can be immediately reused to manufacture articles for both daily use and industrial use.
