As a way of giving back to the community, they save the 55 ac area as a landfill site, with an average depth of compacted refuse limited to 13 ft. LGU estimated that the compacted refuse will have a unit weight of 480 lb/yard3 and that 75% of volume will be taken up by the compacted refuse. What is the useful life of the SLF (year)?

A municipality with a population of 120,000 is under state mandate to recycle 20% of the solid waste generated by its citizens. The remaining 80% will be landfilled. The per capita waste generation rate is 2.2 kg/day. The landfilled waste in-place maximum compacted density is 820 kg/m3, and the soil-cover-to-compacted-waste ratio is 1:4 by volume. The landfill covers a rectangular area 400 m by 500 m. The maximum landfill height cannot exceed 25 m with 1:1 side slopes. What is the operating life of the landfill?
