Tamaki WRAP

Tamaki WRAP Bus Trip


Tamaki Wrap stands for Tamaki Waste Reduction Action Project. They are trying to reduce the amount of rubbish which goes to landfills by teaching the people of Tamaki to eat food with no rubbish and reuse their rubbish. They are trying to teach us to Reduce, Recycle and Re-use by helping us sort the rubbish.
  • Bus to take us there
  • Lots of people
  • Heading out west
  • Morning Tea and Lunch provided
  • In 2016, the Auckland council will be charging people for their landfill rubbish - pay per lift, recycling bin and food waste bin - paid with rates
  • Waitakere Refuse and Recycling Transfer Station
  • Waste Minimization Learning Centre
  • In a typical Akld rubbish bin: 40% food waste, 10% green waste, 35% rubbish and 15% recyclable
  • In Tamaki- 40% rubbish, 50% compostable and 10% recyclable
  • 1 of 16 transfer stations in Auckland region
  • 250 tonnes come on this site everyday
  • In a week, the rubbish can fill a rugby field up to the goal post and that is only in Auckland
  • 1.2 million tonnes a year
  • There are only four landfills for Auckland which are Whitford, Redvale, Claris and Hampton Downs
  • There used to be between 2 and 4 hundred landfills in Auckland but they closed and are now parks and football fields
  • The three problems about landfills are Methane Gas( contributes to global warming ), Leachate and the sheer size of them so you can not build on them or grow things on them
  • Hampton Downs - 700 acres and will be 70m high when it is filled
  • fund of $500,000 dollars a year


The next part of the trip was going to VISY in Onehunga, the most advanced factory in the southern hemisphere

  • MRF - Materials Recovery Facility
  • 3 steps in their process - Collection, Sorting and Processing
  • 85,000 tonnes is recycled each year ( not North Shore or Waitakere )
  • Different recycling methods: handsort to remove contamints, recycle by weight, magnets to collect tins, optic cameras and air jets for plastic
    Glass stays in NZ and rest is sent away overseas, eg milk bottles get turned into plastic beads overseas, then come back to NZ and are made into bottles, eg Coke and Pump bottles
    The number 1-7 in the recycling triangle tells you the type of plastic not if it is recyclable
    Hard/rigid plastic from kitchen/bathroom/laundry can be recycled but soft plastics can not be recycled
    Leave lids on glass and plastic bottles
    No plastic bags
    No open cell meat trays
    No nappies
    No hazardous materials, eg gas cylinders
    Newspaper in a landfill for 40 years and was dug up and you could still read it and that is because there is no air to decompose it
