Battery recycling is essential process

After dealing with the recycling cycle of paper and cardboard waste and glass, Clikeco deals with the case of batteries, batteries and accumulators. Why recycle? What is the battery recycling cycle? Answer in this article!

The need to recycle batteries, batteries and accumulators

Batteries are dangerous because they contain heavy metals that accumulate in our bodies and in our environment. There is mercury , but also lead , cadmium , lithium , nickel , zinc , and so on.

These heavy metals are known to be dangerous for the environment. A pile of mercury thrown into the wild is enough to contaminate 1m3 of earth and 1000m3 of water for 50 years! With mapquest kinsbursky brothers the deal has reached a new height.

But they are also dangerous for our health! Our body does not know how to eliminate these toxic metals, which accumulate irreparably and can at certain concentrations lead to poisoning causing neurological disorders, kidney and blood disorders. Our exposure is multiple and can be indirect via our food chain …

Battery recycling processes

The treatment of batteries is very complex, because of their composition but also their very varied forms.

All recovery operations must therefore take into account the presence of all elements constituting them, such as electrolytes and electrodes.

Thus there are several processes for recycling batteries, batteries and accumulators:

By distillation and pyrolysis to treat especially high mercury batteries;

By hydrometallurgy, to treat alkaline and saline batteries;

Pyrometallurgy, to treat starter batteries and saline and alkaline batteries

The treatment of batteries, batteries and accumulators makes it possible to recover, after refining: nickel, cadmium, zinc (in oxidized or metallic form), manganese (in the form of ferro-manganese or manganese oxide), iron (in the form of ferromanganese or scrap), mercury (after distillation and refining, in the form of liquid purified metal).

In total, with a ton of battery, it is not less than 600 kg of reusable materials that can be extracted! In these 600 kg, one finds 300 to 350 kg of zinc, 20 kg of nickel or 2 kg of mercury. The one contained in a single battery enough to pollute 40 liters of water for 50 years, it is easy to understand the need not to let it spread in the environment.

The materials obtained are then reinjected into the industrial circuit:

  • Lead and cadmium to make new batteries,
  • Manganese in high wear-resistant parts such as backhoe buckets
  • Nickel in household and building accessories,
  • Zinc in the gutters of rainwater recovery …
  • The batteries and accumulators present real dangers for the environment, in particular the grounds , by the substances they contain, if they are not recycled.
  • A battery consists of two electrodes, the anode and the cathode. They are bathed in a more or less liquid solution called electrolyte.
  • The anode consists of materials chosen for their ability to release electrons.
  • They are usually metals (lead, iron, zinc, cadmium, calcium, aluminum, magnesium, lithium) or hydrogen.
  • The cathode is made of materials capable of fixing electrons. Sulfur, halogens or metal oxides are used.
