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]##
