LEAD ACID BATTERY RECYCLING OPTIONS
The washed and dried polypropylene pieces are sent to a plastic recycler, where the chips are melted and extruded to produce plastic pellets for use in the manufacture of battery cases.
Although certain processes will combine the waste lead streams, the most efficient plants feed the paste to the smelting furnace to recover soft lead and the grids and terminals are sent to a melting furnace for the production of hard lead. Lead bullion from both sources will be refined, cast into ingots and sold to the battery manufacturer. The soft lead is suitable for battery paste and the hard lead bullion ideal for grids and terminals.
Polyethylene separators can be separated from the polypropylene waste stream and recycled, although in most secondary plants the current practice is to use this waste as a fuel supplement.
Used battery acid can be handled in four ways: Neutralized, and the resulting effluent treated to meet clean water standards and then released into the public sewer system.
Reclaimed and after topping up with concentrated acid then used as the electrolyte in new batteries
Chemically treated and converted to either agricultural fertilizer using ammonia or to powered sodium sulfate for use in either glass and textile manufacturing or as a filler or stabilizer in household laundry detergent.
Converted to gypsum for use in the production of cement or by the construction industry in the manufacture of fiber board.

The sulfuric acid can be recycled and used in new batteries; it can be neutralized, purified, and tested before being released as clean water; or it can be converted to sodium sulfate, a product used in fertilizer, dyes, and other products.
