The lead acid battery industry has a global annual turnover of USD 6.5 trillion, or about NRs. 728 trillion. However, it also includes recycling used batteries, which is the most polluting process in the world.

According to Farid Ahmed, chief analyst at Wood Mackenzie, the value of the smelter, which is mainly recycled from lead metals from used batteries, is estimated to be. 1.75 trillion in 2021. Lead is the main ingredient used in lead acid batteries.



At present, lead on the London Metal Exchange is close to two thousand dollars or 23 lakh 80 thousand rupees per ton. Lead battery recycling is the world’s most polluting industry, according to the environmental agency Pure Org & Green Cross Switzerland.

The United Nations International Children’s Emergency Fund Pure Earth report has stated that Lead is a powerful neurotoxin. The risk is particularly high in children. This is linked to a decrease in their IQ score.

According to the World Health Organization (WHO) and the United States Centers for Disease Control and Prevention (CDC), a blood lead level (BLL) of more than 5 micrograms of lead per deciliter (UGDI) is considered dangerous.

According to a report by UNICEF and Pure Earth, about 800 million children worldwide are in danger due to lead metals. According to a report by UNICEF and Pure Earth, half of the world’s lead acid battery recycling ends up in the informal sector.

According to a white paper released by the Global Battery Alliance in partnership with the World Economic Forum, there are between 10,000 and 30,000 unofficial battery recycling sites worldwide. Dr. Steve Bryns, director of international lead association regulatory affairs, said Africa, India, Bangladesh, and Indonesia were in a region frightened by informal recycling.

However, not all operations are informal or in poor standard conditions. According to Wood Mackenzie, by 2020, about 124 million tons of refined glass will be produced from primary or secondary sources.



About two-thirds of refined products are produced through recycling. ILJSG estimates that about 86 percent of the world’s lead acid batteries are refined lead. The International Lead Association estimates that about 60 percent of cars use lead acid batteries.

Lead acid batteries are used in forklifts and cranes such as industrial machinery, as well as in data centers and e-bikes. China is the largest player in terms of battery consumption after Europe and the United States.
