Answer:
1.015 ha.
Explanation:
To calculate the landfill area required for 12,000 people producing waste over 10 years, follow these steps:[STEP ONE: Calculate the average solid waste generated per person per year (kg p^-1 ^y(kg/py)).
According to the problem, the average solid waste produced is 2.78 kg per person daily (kg/pd), hence converting to kg/py involves:
2.78 × 365 days = 1014.7 kg/py.
STEP TWO: Determine yearly volume of refuse per person.
Thus, volume = 1014.7 kg/py ÷ 500 kg/m^3 = 2.03 m^3 per person per year.
STEP THREE: Calculate total solid waste volume over 10 years for 12,000 individuals.
Total waste volume over 10 years = 10 × 12,000 × 2.03 = 243,600 m^3.
STEP FOUR: Find the required area for the landfill.
Note: The total height for the landfill should be 20 + 4 = 24m.
Thus, the area for the landfill = 243,600 m^3 / 24m = 10,150 m^2.
If 10,000 m^2 equals 1 ha, then 10,150 m^2 ÷ 10,000 m^2 = 1.015 ha.
(f). Ensure to expand the landfill area for enhancements.
