8. A city generates 50,000 tonnes of solid waste per year and a sanitary landfill is being contemplated to handle the waste on the city outskirts. It is expected that the waste will be delivered by a truck on a 5 d/week basis.

The solid waste has a mean density of 250 kg/m3. It will be spread in 0.75 m layers and compacted to 0.25m. A daily soil cover of 0.15 m and an intermediate cover of 0.30m will be used.

A final cover of 1.0m over the stack of 2 cells is recommended. Ignoring the soil volume between the stacks, determine the annual horizontal area covered by the solid waste. [16]
