This method was built depended on multiplying the expectedpopulation number for the specific year by the average of municipality solidwaste generation rate for the last eight years (GRWA) from 2009 to 2016 as afixed value.
The average municipality solid waste generated was determinedthrough dividing the average quantity of municipality solid waste (Qs) for years2009-2016 by the average population (P) for years (2009-2016) of Sulaymaniyahcity using Eq. (3.8): GRWA= Where:GRWA:Average generation rate of municipality solid waste kg / (capita.
day).Qs(av.):Average quantity of municipality solid waste for years (2009-2016) (kg).P(av.):Average Population of Sulaymaniyah city for years (2009-2016).
Eq. (3.9) (Jarabi, 2015; United Nations, 1952) was used to determinethe population for each year from 2016 until 2032. Where:Pt:Future population at the end of period.
Po:Present population for year 2016.r:The annual population growth rate (2.99 %)t:Number of yearsEq. (3.
10) was used to find the produced solid waste quantityfor year 2032. Using an average waste generation rate for the years 2009-2016then: Qs:Quantity of municipality solid waste produced each year (ton).The cumulative of municipality solid waste quantity generated in 2032 can be determined,as shown in Eq. (3.11): Where:Qs (c):Cumulative quantity of municipality solid waste for the specific year (tonne).Qs (ct): Quantityof municipality solid waste for the specific year (tonne).Qs(ct-1): Cumulative quantity of municipality solid waste for the last yearbefore specific year (tonne).
In order to calculate the cumulative municipalitysolid waste generated by year 2032 For illustration the cumulative municipality solid waste quantityin 2032 Qs(c) is equal to the municipality solid waste quantity of produced in2032 Qs (ct) using Eq. (3.10) plus the cumulative municipality solid waste quantityin 2031 Qs(nt-1) form the year 2016.
