Qs:
Quantity of solid waste for one year (kg).

P:
Population of city for one year.

The rate of increment for solid waste generation rate of Sulaymaniyah
city was 0.013 (kg /capita / day) (RGI) based on values of waste generation
rate in 2009 and 2016 is:

Where:

RGI:
Rate of increment for waste generation rate.

GRW2016:
Generation rate of solid waste was 0.794 (kg / capita / day) of year 2016
(Sulaymaniyah directory of municipality).

GRW2009:
Generation rate of solid waste was 0.69 (kg / capita / day) of year 2009
(Sulaymaniyah directory of municipality).

n:
Period (years).

The population for each year from 2016 until 2032 was
calculated as follows:

Eq. (3.16) is used to calculate the generation rate of solid
waste for year 2032 or specific year (GRSW) based on present generation rate of
solid waste for year 2016 from Eq. (3.13) and rate of increment for waste
generation rate of each year from Eq. (3.14), this equation similar to equation
that used by (Al-Rawi and Al-Tayyar, 2012).

Where:

GRSW:
Generation rate of solid waste for each year.

GRW:
Present generation rate of solid waste for year 2016 from Eq. (3.13).

RGI:
Rate of increment in waste generation per year from Eq. (15).

n:
Number of year.

The quantity of waste (Qs) produced each year till year 2032
was based on generation rate of solid waste for specific year (GRSW) from Eq.
(3.16) and future population for specific year (Pt) from Eq. (3.14) was
calculated as:

Or

Qs:
Quantity of waste produced each year (tonne).

The cumulative quantity of solid waste generated by 2032 can
be calculated as:

Where:

Qs
(c): Cumulative quantity of solid waste for the specific year (tonne).

Qs
(ct): Quantity of solid waste for the specific year (tonne).

Qs
(ct-1): Cumulative quantity of solid waste for the last year before specific
year (tonne).

– For example the cumulative quantity of solid waste in 2032
Qs(c) is equal to the quantity of solid waste produced in 2016 Qs(ct) from Eq.  (3.18) by adding the cumulative quantity of solid
waste in 2031 Qs(nt-1) to quantity of solid waste in 2032, accumulatively from
year 2016 until 2032, the increment is done through adding the value of current
year to past year until year 2032 as:
