Sanitary landfill is a method used to backfill solid waste. The landfill site needs special engineering specifications after doing a geological study of the site so as to ensure that the environment is not harmed by the leakage of liquids resulting from the decomposition of waste to groundwater, and the method depends on solid waste stacking, To hold more quantity and to reduce waste leakage, the waste should be covered daily with an insulating and impermeable clay layer.
