Waste portable and industrial batteries and accumulators (WBA)

Nord holding accepts and deliver for recycling waste
portable and industrial batteries and accumulators.

Batteries and accumulators are divided according to the following indicators.

According to the source of energy,
they are divided into:

  • PRIMARY BATTERIES
    primary source of energy batteries that are not rechargeable.
  • SECONDARY BATTERIES AND ACCUMULATORS
    secondary source of energy batteries subject to recharging.

According size and application,
they are divided into:

Portable batteries and accumulators

Portable batteries are small in size (under 2 kg.) and are extremely diverse
according to their constituent materials and internal chemical compounds.

Common in our daily life portable batteries and accumulators are:

  • ALKALINE
  • CARBON-ZINC
  • AIR-ZINC
  • LEAD
  • NICKEL-CADMIUM
  • NICKEL-METAL HYDRIDE
  • LITHIUM-ION
  • LITHIUM-POLYMER
  • BUTTONS AND OTHERS

The most popular primary portable batteries are alkaline batteries, which are small,
usually cylindrical, and are used in households to power remotes, toys, etc.

The most popular secondary batteries are lithium-ion batteries, which are used in consumer electrical appliances
and portable electronic devices for household use.

Industrial batteries and accumulators

Industrial batteries and accumulators are diverse in composition, the most common being:

  • LITHIUM-ION
  • OTHERS WITH LITHIUM
  • AIR-ZINC
  • LEAD-ACID
  • NICKEL-CADMIUM
  • WITH SILVER OXIDE

Industrial batteries are used in:

Recycling process

The process of recycling, recovery
or disposal of portable and industrial
WBA includes the following operations:

  • ACCEPTANCE
    Portable WBA are accepted by both individuals and legal entities. Industrial WBAs are accepted only by legal entities.
    When handing over to our site, all the documents that are required according to the current legislation are drawn up. A specific requirement for delivery of batteries and accumulators containing liquid is that they be delivered with a robust case, caps available and liquid stored.
  • PURCHASE
    Nord Holding buys used batteries and accumulators for a fee or accepts them free of charge, depending on their type and how they will be processed in recycling plants.
    Due to the cost of recycling exceeding the value of the recovered materials, certain types of batteries and accumulators are accepted only by prior agreement with the supplier for a fee.
  • SORTING
    After receiving the WBA at our site, trained personnel separate the batteries by type. Separation takes place according to the available marking on the battery case. If this is missing for portable batteries, they are stored and sent for recycling as unsorted.
  • STORAGE
    WBA are stored separated by type, in special containers – leak-proof plastic barrels and boxes, which are stored in closed rooms or under a shed.
  • TRANSPORT
    WBA can be hazardous and non-hazardous according to environmental legislation and dangerous and non-dangerous according to the international ADR convention for the carriage of dangerous goods. Each individual type of WBA is transported according to the requirements of both classifications.
  • RECYCLING
    All delivered batteries and accumulators are handed over to recycling facilities in Bulgaria and in countries of the European Union, specialized for specific types of batteries.

Before submitting WBA for recycling, we require facilities
to ensure that they meet the requirements of European legislation for minimum recycling percentage
thresholds per battery types.

Typically, the recycling process of WBA includes:

  • DISASSEMBLY OR
    MECHANICAL SHREDDING
  • SEPARATION OF THEIR CONSTITUENT
    MATERIALS BY VARIOUS PROCESSES
  • RECYCLING OF ALREADY SEPARATED MATERIALS
    THROUGH SPECIFIC PROCESSES

Alkaline and air-zinc portable batteries

  • SHREDDING
    Mechanical treatment to separate materials by shredding. Ferronickel and black mass are separated.
  • RECYCLING OF FERRONICKEL
    Ferronickel is handed over for recycling by the metallurgical industry.
  • PROCESSING OF BLACK MASS
    Black mass is processed in a rotary kiln to obtain slag used in road construction, zinc oxide used in the zinc industry and carbon.

Nickel-cadmium batteries and accumulators

  • MECHANICAL TREATMENT
    Mechanical pre-treatment for separation of the outer plastic cases that are recycled into new plastic products.
  • VACUUM-THERMAL TREATMENT
    Followed by vacuum-thermal treatment, carried out in a vacuum furnace, in which ferronickel alloy is extracted through gradual heating and physico-chemical processes, and through additional condensation – water, oil and cadmium.
  • APPLICATION OF THE RAW MATERIALS OBTAINED
    Ferronickel alloy is a raw material for the metallurgical industry, and cadmium is used to alloy it with metals to improve their properties, to obtain brazing alloys, to galvanize metals to prevent corrosion, and to produce anodes or cathodes for storage batteries.

Lithium-ion batteries and accumulators

  • SHREDDING
    Batteries are shredded and the electrolyte is extracted.
  • SEPARATION
    By means of magnetic separation, iron is separated, and by means of various subsequent separation methods – plastics, binders, copper, aluminum, graphite and salts of lithium, cobalt, nickel and manganese.
  • APPLICATION OF THE RAW MATERIALS OBTAINED
    The salts of lithium, cobalt, nickel and manganese are processed and material is obtained for the production of cathodes, which are reused in lithium-ion batteries.

    Graphite, aluminum, copper and iron are also processed and can be used to make lithium-ion batteries or other energy storage systems, the production of ceramics, pigments, adhesives, paints and more.

Benefits

Recycling waste portable and industrial batteries
and accumulators gives us valuable raw materials such as:

  • FERRONICKEL ALLOY
  • LEAD
  • COPPER AND ALUMINUM
  • SALTS OF LITHIUM, COBALT, NICKEL AND MANGANESE
  • CADMIUM
  • PLASTICS AND CHEMICAL PRODUCTS

These materials are fed back into industry, offsetting
the limited natural resources mined for their production.

Important information:

Batteries and accumulators are an important part of modern man’s daily life – from the mobile phone, laptop, electronic game and remote control to the tram and the electric car.

Seemingly inconspicuous as part of other appliances and equipment, their quantity is actually huge, so if they are landfilled or thrown into general waste, they can cause significant damage to nature.

The reason for this is that they contain dangerous substances that can poison water and soil – for example – the acid in a car battery, the mercury in button batteries, the cadmium in nickel-cadmium batteries, etc.
