  1. Monuments of the Millennia Sanitary Landfill/ Solid Waste Disposal Group F: IlianaGamboa Miriam Garcia Daniel Perez Ricardo Felix Saul Mejia Andrea Rios

  2. Facts • Americans generate trash at an astonishing rate of 4.6 pounds per day per person. [4] • 32.5 percent, was either recycled or composted. [4]

  3. Landfills in History • In around 3000 BC in the Cretan capital, Knossos, waste was placed in large pits and covered with dirt at various levels.[1] • In the1920’s the first official landfill was created in England.[2] • In US, the first government established sanitary landfills were built in the 1930s.[2]

  4. What is a landfill? • It is a way of disposing waste. • A secure landfill is a carefully engineered depression in the ground into which wastes are put. • The aim is to avoid any hydraulic connection between the wastes and the surrounding environment, particularly groundwater.[3]

  5. Types of landfills • Municipal Solid Waste Landfill • Industrial Waste Landfills • Construction & Demolition Debris Landfills

  6. Municipal Solid Waste Landfill (MFWLs) • Municipal solid waste landfills receive household waste. • MSWLFs can also receive non-hazardous sludge, industrial solid waste, and construction and demolition debris.[4]

  7. Industrial Waste Landfill • Items such as organic chemicals, inorganic chemicals, steel, plastics and resin manufacturing are allowed in IWL. • American industrial facilities generate and dispose of approximately 7.6 billion tons of industrial solid waste each year • After an ISW landfill is closed, the facility is maintained and monitored for 30 year.[6]

  8. C&D Debris Landfill • C&D materials often contain bulky, heavy materials, such as concrete, wood, metals, glass, and salvaged building components. • Reducing and recycling C&D materials conserves landfill space, reduces the environmental impact of producing new materials • Household garbage, electronic equipment, fluorescent bulbs, liquid waste and utility poles cannot be disposed of in a C&D debris landfill.[7]

  9. Environmental Problems • Water emissions • Atmospheric emissions • Landfill fires • Decomposition • Landfill leakage [2]

  10. Improvements • Redesigning landfills is a main solution to prevent contamination of the environment. • One of the most important ways to improve the landfills is to reduce the amount of garbage produced by the average American home.[2]
