Mumbai Top Waste-Generating Metro In India
Maximum City Mumbai has become the maximum waste-generating metro in the country. According to a report, EnviStats 2018, published by the Ministry of Statistics and Programme Implementation, Mumbai produced 11,000-tonne waste every day in 2016-17, up from 5,355 tonne per day in 1999-2000. These numbers were collected by Central Pollution Control Board (CPCB) until August 2017.
Here’s what the numbers of the report reflect.
Looking at how Mumbai has performed, Maharashtra as a state is the highest waste generator in the country with 21,867 tonne per day in 2016-17. Of this only 6993 tonne was treated per day while 14894 tonne was landfilled across eight landfill sites.
The second in the list is Uttar Pradesh with 19,180 tonne of waste generated every day, followed by Tamil Nadu at 14,500 tonne per day and Gujarat 10,480 tonne per day.
While Mumbai is the leading metro when it comes to waste generation, closely following is Delhi. The national capital generates over 8,700 tonne of waste every day. What is alarming is the pace at which waste generation has grown in Delhi over the years. While Delhi generated only 400 tonne of waste every day in 1999-2000, the number swelled drastically in 2004-05 to 5,922 tonne to 6,800 tonne in 2010-11. Similarly, Bengaluru, which stands at third position with 3,700 tonne waste every day, used to generate only 200 tonne waste in 1999-2000, followed by 1,669 tonne in 2004-05 and 3,700 tonne in 2010-11.
Based on the numbers highlighted in the EnviStats 2018 report, one of the biggest pain points in terms of solid waste in India is its treatment. Even while 100 per cent of waste is being collected everyday only 23 per cent of this is being treated while another 27 per cent is being sent to landfill sites. The remaining half of the waste is, according to CPCB, being used by private recyclers dumped; treated at smaller dumping grounds at district or village levels; treated at source by large societies, factories or industries; or dumped at smaller collection points. The percentage that is being dumped in open grounds and places could be a cause of diseases and unhealthy living environment.
The need is to have better waste management models not just across metro cities but also across smaller yet emerging cities that are going to be the industrial hubs in the future.
