Battery Recycling

battery recycling is a process that is designed to reduce the number of batteries being disposed of as material waste. This reuse and reprocessing practice comply with all environmental guidelines and rules within the UK. As a result, the amount of poisonous chemicals and heavy metals at local and national dump sites is greatly reduced. This ensures a cleaner and safe environment, along with batteries that can be redistributed for personal, industrial and commercial usage.

The Process in Detail

Most batteries can be recycled across the UK. However, there are some that can easily be recycled more than others. This includes lead batteries, which are 99% recyclable due to their toxicity and lead levels. Similarly, nickel metal hydride, lithium, nickel zinc, and nickel-cadmium batteries can be recycled as well. Here are some essentials for recycling some types of batteries for environmental concerns and compliance.

Recycling Lead Acid Batteries

The first step in recycling lead-acid batteries is the collection. Local teams simply collect these units from area collection and disposal points for transfer to nearby recycling facilities. These batteries are then crushed into small pieces within a hammer mill. The next step is to sort out the broken pieces via a vat, which allows heavy metals and lead to separate from plastics. Sieving is then performed to scoop out polypropylene pieces while eliminating liquids to leave only the heavy metals and lead. The polypropylene pieces are then washed, while ferried downstream for manufacturing new battery casings.

The hydro-metallurgical and pyro-metallurgical processes extract essential metals and minerals from their ores. This is the final process in battery recycling, which extracts heavy metals and leads from battery residue. This process is intricate and detailed in nature for these types of recycling purposes. In fact, it helps facilitate the physical and chemical transformations for lead and metal recovery. From calcinations and roasting to smelting and refining, this process leads to the final recycled product for mass use across the UK.

What about the extracted plastics?

As mentioned earlier, plastic pieces are extracted, washed and dried for plastic recycling. They are also used to manufacture battery casings, and some units are even sold to local manufacturers are raw materials. Led materials are thoroughly cleaned to eliminate any impurities. The final products are poured into ingot molds and left to dry and cool. After this process is done, the units are taken out from the mold and ferried to battery manufacturers. They are now ready to be used as new lead plates, as well as battery components for all types of applications.

Removing Battery Acid with Recycling

As with any battery recycling, there is strong concern about battery acid leaking out. However, there are some methods applied to reduce and eliminate acid from deterring the overall process. This includes neutralization of the acid that turns it into the water. This is done with industrial basic compounds, which secure clean water that is tested and treated before release into local sewer systems. Battery acid can also be converted into sodium sulfate. The latter is a white powder -- with no odor -- that is utilized for making textiles, glass and laundry detergent. The acid can even be recycled and reused to create new battery products. However, this is a special process that is lengthy in nature.
