Acid, lead and other harmful chemicals from over 3,00,000 expired batteries, used in auto-rickshaws and motorised three-wheelers, are posing a serious threat to human health and environment.

There are at least 25,000 easy bikes and 11,000 auto-rickshaws in the city, according to Khulna Easy Bike Kallyan Samity and Easy Bike Chalok Samity. An easy bike uses five batteries while an auto-rickshaw has four.

These batteries remain usable for about eight months. This means, every year, an estimated 2,41,000 batteries are discarded.

Arman Munshi, an easy bike driver, said he sells six to seven expired batteries every year, each weighing 18-19 kg, to businesses at Sheikhpara Batterypatti at Tk 95 to Tk 100 per kg.

Soleman, a local battery trader, said there were more than 500 shops in the city that buy expired batteries and collect lead to sell it again to battery factories.

Kamruzzaman Sarkar, a chemist of the Department of Environment, blamed the lack of monitoring for the situation.

He said the lack of policy on the management of expired batteries meant that they were treated like any other waste.

Gallons of acid from these batteries are dumped into drains while the lead is sold to retail buyers. The batteries are melted in high temperature.

Md Anisur Rahman, conservancy officer of Khulna City Corporation, said they were monitoring the situation and would take legal steps against battery businesses that were polluting the environment.

Kamruzzaman said lead and acid from the rejected batteries were eventually entering the food chain and the human body, causing serious health issues.

Professor Dilip Dutta, who teaches environmental science at Khulna University, said lead and sulphuric acid from expired batteries were more dangerous to human health than the environment.

‘If these chemicals enter the human body, they can damage the brain, and sometimes people can become handicap. These chemicals may also cause cancer,’ he said.
