IIT Madras and IIT Kanpur researchers study policy tools
IIT Madras and IIT Kanpur researchers study policy tools are conducting a study to find out the appropriate policy instruments that can help India to bring down lead pollution.
The research units from IIT Madras and IIT Kanpur joined hands to look collectively at the problem of lead cycling in India as lead pollution can harm the mental and physical health of people and can contaminate the environment.

The sources from IIT Madras and IIT Kanpur further said the lead is melted in open furnaces due to which poisonous gases reach the air. This way of lead recycling is not only harmful to the environment but also the health workers engaged in the recycling process.
Low cost
However, the low cost of this manoeuvre makes it still an attractive choice, say sources from IIT Madras and IIT Kanpur. The presence of the informal sector and its undesirable consequences are more predominant in developing countries where the costs and lenient regulations and laws have helped the unregulated sector to grow at a faster pace, say sources from IIT Madras and IIT Kanpur.
The study
IIT Madras and IIT Kanpur researchers study suggested that the policy guidelines such as reducing the tax on the regulated recycling sector and providing subsidies to regulated recycling and remanufacturing sectors reduce lead pollution from lead-acid battery recycling.
Another important finding in the study by IIT Madras and IIT Kanpur researchers study policy tools is that a very high subsidy to the formal remanufacturing sector can lead to the shutting down of both regulated and unregulated recycling sectors.
The team from IIT Madras and IIT Kanpur published the results of their work in the esteemed international research journal Resources, Conservation and Recycling.(https://doi.org/10.1016/j.resconrec.2021.105528)
Importance
Professor R.K Amit spoke on the importance of the research taken up by team from IIT Madras and IIT Kanpur.
‘The insufficiency of primary lead sources to satisfy the demand makes the recycling of used batteries necessary.’
However, the unscientific way of recycling by the unregulated sector poses serious environmental and health threats due to the high amount of lead excretion, said Professor Amit.
‘We studied to quantitatively assess the impact of different policy instruments on shifting the recycling business from unorganized to the organized sector in India.’

Though high lead levels are equally harmful to grown-ups, the high levels of lead in children are known to reduce IQ, decrease attention span, cause anaemia, kidney and liver disorders, among other issues in children.
In their publication, Mr. Brahmesh Vinayak Joshi, Dr. B Vipin, Dr. Janakarajan Ramkumar, and Dr. R K Amit assessed the impact of policies such as reducing the tax on regulated recyclers, subsidies to organized recyclers and formal battery remanufacturers on the performance of battery recycling to name a few.
The researchers from IIT Madras and IIT Kanpur used a system dynamics model to explore the implications of economic policies quantitatively on the recycling of used lead-acid batteries.

Professor Amit said from the implementation point of view, the policymakers can consider the results of this study to frame policies and rules for the LAB recycling activity in India.
As a natural course of future research, the implication of these policies on the social dimension, in terms of job loss in the unorganized sector and possible ways through which the unorganized sector’s workforce can be integrated with or relocated to the organized sector will be explored, he said.
Lead
Lead is used in various industries such as paints, cosmetics, dyes, ammunition, and jewellery, among numerous others, but the battery sector remains the major consumer of this metal by utilizing 85 per cent of the production, say sources from IIT Madras and IIT Kanpur.
Several rules on battery waste management, handling and recycling have been put in place at appropriate times by the respective countries to handle the lead pollution.
Sources from IIT Madras and IIT Kanpur say recycling was put forward as a good way to deal with the scarcity of metal and to handle the accompanying pollution.
However, the proper recycling of lead is still a concern and it is lagging due to mushrooming of the unregulated battery recycling sector alongside the regulated ones.
