Spent lead-acid batteries are taken to recycling facilities where they are broken down and separated into components to begin the recycling process. The components that are separated during the process are: lead-containing materials, plastics and acids, which are further recycled/processed separately. Recovered lead is smelted and purified for use in all areas of the lead industry, including battery manufacturing, lead chemicals and manufactured products. Recycled plastic is used in plastic components and manufacturers for new battery cases and other consumer products. The acid is safely collected in acid collection tanks for direct sale or further neutralization.
