Lead Acid Batteries
The battery is broken apart in a hammer mill, a machine that hammers the battery into pieces. The broken battery pieces are then placed into a vat, where the lead and heavy materials fall to the bottom and the plastic floats. At this point, the polypropylene pieces are scooped away and the liquids are drawn off, leaving the lead and heavy metals. Each of the materials goes into a different recycling “stream”
Polypropylene pieces are washed, blown dry and sent to a Polypropylene recycler. And the battery boxes which left we cut those boxes and convert in to the small pieces (pallets)
And then reuse to make new plastic products
Lead grids, lead oxide and other lead parts are cleaned and heated within smelting furnaces. The molten melted lead is then poured into ingot molds. After a few minutes, the impurities float to the top of the still molten lead in the ingot molds. These impurities are scraped away and the ingots are left to cool, to find more information visit http:/thedublinpainters.ie/. When the ingots are cool, they’re removed from the molds and sent to battery manufacturers, where they’re re-melted and used in the production of new batteries.
Old battery acid can be handled in two ways: 1. The acid is neutralized with an industrial compound similar to household baking soda. Neutralization turns the acid into water. The water is then treated, cleaned, tested in a waste water treatment plant to be sure it meets clean water standards. 2. The acid is processed and converted to sodium sulfate, an odorless white powder that’s used in laundry detergent, glass and textile manufacturing.
Lead acid batteries are closed-loop recycled, meaning each part the the old batteries is recycled into a new battery. It is estimated that 98% of all lead acid batteries are recycled.
