Indore: As many as 1,900 tons of urban waste every day could throw any city the size of Indore out of gear. But the largest city in Madhya Pradesh does not worry about waste instead turns it into crore of rupees as well as fueling its buses.
Indore's innovative garbage management earned the city the title of India's cleanest city for sixth time followed by Surat and Navi Mumbai when the Union government's annual cleanliness survey announced results on Saturday.
While segregation of garbage into dry and wet categories is common, in Indore segregation happens in six categories at a collection point.
Indore with a population of 35 lakh, also known as the state's commercial capital, is garbage bin-free, even though it generates 1,200 tons of dry waste and 700 tons of wet waste daily.
"We have 850 vehicles which collect waste from households and business establishments and segregate it into six categories," said Mahesh Sharma, cleanliness wing superintendent engineer of the Indore Municipal Corporation (IMC).
The vehicles have separate compartments for different types of waste. Discarded sanitary napkins, for instance, go into a separate compartment.
This sorting at the initial stage of collection comes in handy for efficient processing, Mr Sharma said.
The highlight of the IMC's waste disposal process is a bio-CNG plant which runs on the wet waste collected from the city. It is Asia's largest such facility, according to city officials.
On February 19 this year, Prime Minister Narendra Modi inaugurated this 550 MT per day capacity plant worth ₹ 150 crore at the Devguradia trenching ground.
It can generate 17,000 to 18,000 kg of Bio-CNG and 10 tons of organic manure.
As many as 150 city buses are being run on this Bio-CNG which is ₹ 5 cheaper than commercial CNG.
The IMC earned ₹ 14.45 crore from waste disposal last fiscal, including ₹ 8.5 crore from the sale of carbon credits in the international market and ₹ 2.52 crore as annual premium from a private company for providing waste to the bio-CNG plant.
In the current fiscal, the civic body hopes to earn ₹ 20 crore from waste disposal, said Sharma.
As many as 8,500 safai mitras (sanitary workers) work in three shifts to keep Indore clean, he added.
Sewage generated in the city too is treated at three special plants and reused at 200 public gardens, farms and for construction activities, said horticulture officer Chetan Patil.
