India’s Population = 1027 Million
As per 2001 Census
Urban Population = 285 Million
Urban Areas = 5161

3. As percentage of total 17.3% 25.72% 27.8% 41%
Population
MAGNITUDE OF PROBLEM
- Per capita waste generation increasing by 1.3% per annum
- With urban population increasing between 3 – 3.5% per annum
- Yearly increase in waste generation is around 5% annually
India produces 42.0 million tons of municipal solid waste annually at present.
- Per capita generation of waste varies from 200 gm to 600 gm per capita / day. Average generation rate at 0.4 kg per capita per day in 0.1 million plus towns.
- Collection efficiency ranges between 50% to 90% of the solid waste generated.
Urban Local Bodies spend around Rs.500/- to Rs.1500/- per ton on solid waste management of which,
* 60-70% of the amount is on collection alone
* 20% - 30% on transportation
* Hardly any fund is spent on treatment and disposal of waste
- Crude dumping of waste in most of the cities

% OF TOTAL GARBAGE
WASTE GENERATED IN 6 MEGA CITIES 21,100 TPD 18.35%
WASTE GENERATED IN METRO CITIES 19,643 TPD 17.08%

WASTE GENERATED IN OTHER 42,635.28 TPD 37.07%
CLASS-I TOWNS
(0.1 MILLION PLUS TOWNS) ____________ _________
83,378.28 TPD 72.50%
IF WASTE PRODUCED IN ALL CLASS-I CITIES IS TACKLED, PERCENTAGE OF WASTE SCIENTIFICALLY MANAGED WOULD BE 72.5% OF TOTAL WASTE.
Characteristics of Municipal Solid Waste
Compostable / Bio-degradable = 30% - 55%
matter (can be converted into manure)
Inert material = 40% - 45% (to go to landfill)
Recyclable materials = 5% - 10% (Recycling)
These percentages vary from city to city depending on food habits
