Question

Assuming waste not recovered all goes to landfills. Determine the total landfill capacity consumed
national wide each year. The specific weights of waste at landfill are as follows. Convert your
answer to # of football stadiums filled.
Area of football stadium = 1.75 x size of a standard football field
Depth of filling = 30 ft
Waste category
Specific weight (kg/m³)
Aluminum
2470
Steel and other metals
7100
Glass
2300
Paper and cardboard
570
Wood
450
All others
~700

Expert Solution

Step 1 Given data

depth of filling= 30 ft=9.144 m

$a v e r a g e s p e c i f i c w e i g h t o f t h e w a s t e γ_{a v g} = \frac{2470 + 7100 + 2300 + 570 + 450 + 700}{6} = 2265 k g / m^{3}$

$v o l u m e o f t h e w a s t e t o b e f i l l = d e p t h \times A r e a o f f o o t b a l l f i e l d = 9.144 \times 1.75 \times A r e a o f s \tan d a r d f o o t b a l l f i e l d$
