A municipal landfill has available space of 16.2 ha at an average depth of 10
m. Seven hundred sixtyfive (765) m3 of solid waste is dumped at the site 5 days a
week. The waste is compacted to twice its delivered density. Draw a massbalance
diagram and estimate the expected life of the landfill in years.

Environmental science 
drwls,
Divide the available volume by the annual volume of compacted waste.
The annual volume of compacted waste is (1/2)*765*5*52 = 9.95*10^4 m^3
The 16.2 hectares piled 10 m deep is an available volume of 16.2*10^4*10 = 1.62*10^6 m^3
It will be full in 16.3 years
