Landfills

  • A secure landfill is a strategically designed structure built into or on top of the ground in which rubbish is placed. The intention is to avoid contact with groundwater and the environment. 
  • Although landfills should be the last resort in terms of waste disposal, globally landfilling is still the major waste disposal method.
  • We should follow the principles of:
      • Preventing waste
      • Minimising the amount of waste we produce
      • Reusing what we can
      • Recycling 
      • Only that which we cannot reuse, recycle or compost should make its way to a landfill.
  • One of the major environmental hazards of landfills is their impact on global warming.
  • Landfills produce methane gas as waste decomposes under anaerobic (without air) conditions. Methane gas, a major greenhouse gas, is more potent in its greenhouse effects than CO2.
  • When a landfill leaks ground water is contaminated.
  • Waste decomposes very slowly in a landfill whereas a compost heap will decompose quickly.
  • If you are somewhere where recycling isn’t possible and the garbage is going to land up in a landfill then take the lid off plastic bottles – it’s easier to squash the container flat which takes up less space in the landfill.
      • Flatten cans.
      • Flatten boxes.
      • Flatten milk containers.
