The Camino Real Landfill was required to install a plastic liner to prevent leachate from migrating into the groundwater. The fill area was 43,000 m² and the installed liner cost was $8 per m². In order to recover the investment, the owner charges to unload at the rates of $13 per pickup, $25 per dump truck, and $70 per compactor truck load. The fill area is adequate for 7 years. If the annual traffic is estimated to be 2500 pickup loads, 650 dump-truck loads, and 1200 compactor-truck loads, what rate of return will the landfill owner make on the investment? The rate of return that will be made by the landfill owner, (in %) Round to the nearest two (2) decimal places Hint: compute for internal rate of return Add your answer

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
