Complete the following questions:
1. Estimate the area for a landfill for 12,000 p producing waste for 10 y
(p = people and y = year)
a. Assume that the national average solid waste production can be
applied. 2.87 kg p-1 d-1 (kg/pd)is the national average (d = day).
Convert this to kg p-1 y-1.
b. Assume that the refuse is compacted to 5E2 (5x102) kg/m3.
Find the volume in m3 p-1 y-1.
c. Find the Total Volume for 12,000 p and 10 y.
d. Site investigation finds the groundwater at 5 m below the
surface. The assumption is that the landfill is 20 m high
(above ground) and a box shape. How deep should the landfill
be?
e. Find the Area of the landfill in hectares (ha) (1ha = 10,000 m2)
f. How could this design be improved?
