5.5.2 Management ofSDW

Options

  • Landfill
  • Incineration
  • Recycling
  • Composting
  • Any more?
5 5 2 landfill issues
5.5.2 Landfill Issues

Waste put into ground, and covered with soil, plastic, or both each day.

  • anaerobic decomposition produces methane
  • aerobic decomposition produces carbon dioxide
  • noise, smell, vermin
  • Leachates - seeping liquid into groundwater aquifers
    • Liners used, then encourage anaerobic decomposition
  • Finite amount of area
5 5 2 incinerator issues
5.5.2 Incinerator Issues
  • do not separate materials
    • cleansers, batteries, paint
  • air pollution
    • dioxins
  • creates ash as byproduct
    • 10-20% of original mass
    • where does it go?
  • traffic
    • air & noise pollution
  • very expensive
5 5 2 recycling
5.5.2 Recycling
