A municipal landfill has available space of 16.2 ha at an average depth of 10
m. Seven hundred sixty-five (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 mass-balance
diagram and estimate the expected life of the landfill in years.

  • Environmental science -

    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
