estimate the area for a landfill for 12000 p producing waste for 10 y. assume that the national average is

1.015 ha.

Explanation:

In order to be able to calculate the area for the landfill for 12000 p producing waste for 10 y the following steps must be taken.

STEP ONE: Determine the average solid waste production in kg p^-1 ^y(kg/py).

From the question, we have that average solid waste production is 2.78 kg p^-1 d^- (kg/pd) hence, to change it to kg/py we have;

2.78 × 365 days = 1014.7 kg/py.

STEP TWO: determine the volume of refuse per person in a year.

Thus the volume = 1014.7 kg/py ÷ 500 kg/m^3 = 2.03 m^3 p^- y^-.

STEP THREE: Determine the total volume of solid waste in 10y by 12,000.

Toy volume in 10y = 10 × 12,000 × 2.03 = 243,600 m^3.

STEP FOUR: Determine the are of the landfill.

NB: the total height for the landfill should be 20 + 4 = 24m.

Therefore, the area of the landfill= 243,600 m^3. / 24m = 10,150m^2.

If 10000 m^2 = 1 ha. Then, 10,150m^2 ÷ 10000 m^2 = 1.015 ha.

(f). Make sure to increase the landfill area for improvement.
