BACKGROUND
Zonewise No of Wards
GCC-Computation of waste generation
Waste generation in wards = Ward population* X Per capita waste generation (0.71kg/day)$ X plastic composition(9.5%)##
Ward Population [GCC data]*
Per capita waste generation 0.71kg/Day [ENVIS Department of Environment, Government of Tamil Nadu]$
Plastic composition 9.5% [CPCB Plastic waste as Percentage of Municipal Solid Waste]##
POPULATION
Chennai is the second most
densely populated district next to Delhi
−Population: 6674954 (2011)
−Population Density: 26954/ Sq km
GCC Zone which have high population
- ‒Zone 4 -Tondiarpet
