Waste Management


  • REDUCE
  • REUSE
  • RECYCLE 
  1. In 2010 each person in the UK produced 452 kg of waste
  2. Waste management in the UK is improving 
  3. EU targets want 50% of household waste to be recycles by 2020
Landfill

  • Cheap way of getting rid of waste
  • Releases CO2 and methane, however new technologies that allow gases to be captured can be used 
  • Can pollute groundwater, can be specially lined to prevent this
  • Waste valuable materials that can be reused or recycled
Composting

  • Organic material can be composted by individuals or on a larger scale, 38% of household waste is organic material 
  • Household composting reduces cost
  • Sustainable as reduces the amount going to landfill
  • Has to be managed properly, sorted so that no metal is involved
Recycling 

  • Quicker and cheaper than making materials from scratch 
  • Uses less energy, 20 times less when making aluminium cans
  • Reduces demand for new materials 
  • Relies on individuals and some people don't bother 
  • Initial investment is required 
  • Often is transported abroad to be recycled, in 2005 55% of paper was sent to China
Energy Recovery 

  • Burning of materials that can't be recycled to produce heat or electricity 
  • Produces CO2 but reduces fossil fuels 
  • The Energy Recovery Facility in Sheffield provides heat for 140 building in the city centre 
Reduce and Reuse

  • Can be done by individuals  eg reducing the amount of junk mail you receive or by businesses by reducing the packaging on items
  • Plastic bottles are easily reused by cans are not
