Analytic Hierarchy Process (AHP) for a Landfill Site Selection in Chachapoyas and Huancas (NW Peru): Modeling in a GIS-RS Environment

Table 4

Data for estimating the minimum area for the landfill.

Description	Value/equation	Based on
Generation per capita (GPC)	0.435 kg/ha.day	[45]
Density (ρ)	1010.98 kg/m^3	[45]
Population growth rate (d)	3.3%	[27]
Maximum height of the landfill (h)	6.00 m	[27]
Service life (SL)	20 años	[27]
City population by 2040	Pop2040 = P0 × (1 + d) ^t; t = SL	[27]
Amount of municipal solid waste (MSW) generated in a day	Q2040 = Pop2040 × GPC	[27, 68]
Total volume of MSW generated in one day	Vdiario = Q2040/ρ	[27, 69]
Total volume of MSW generated in 20 years	V2040 = Vdiario × 365 × 20	[27, 70]
Minimum area for a landfill	Amín = V2040/h	[27]
