What is Waste?

Almost every activity using materials and energy generates waste - from mining to manufacturing to cooking dinner.

 

Rubbish

Waste is what people throw away because they no longer needed or wanted it.  We get rid of it by putting it in the rubbish bin.  But do we need to make so much waste?

 

Waste is created in many ways. A baby wearing disposable nappies, manufacturing a vehicle, a person throwing away the packaging from a museli bar, demolishing a building and using a plastic supermarket shopping bag are all examples of activities that generate waste.

 

Waste can be difficult to define, as what one person regards as rubbish could be a useful resource (or treasure) when used again by someone else.  For example, refilling your drink bottle, trading items on trade-me, donating second-hand goods to a local charity or wrapping up your Friday night take-aways in yesterday's newspaper. 

 

Waste Matters

Waste represents an inefficient use of our resources.  It can be bad for our environment, bad for our health and bad for our economy.

 

The improper disposal of waste can have a significant impact on us personally and our environment:
  • Waste is unslightly

  • Decomposing organic waste in landfills makes methane, a harmful greenhouse gas

  • Landfills produce leachate, that can contaminate our water and soil

  • Burning waste can release hazardous and toxic substances

  • Waste creates a large cost, from production to treatment to disposal

 

Wasted Opportunities

We live in a wasteful world.  In 2007, Southlanders threw away over 55,000 tonnes of rubbish - that same weight as 137 Boeing 747's or 7,857 African Elephants.

 

Everything we use and throw away is made from the earth's natural resources - water, oil, gas, coal, air, rocks, plants and animals.  Paper was once a tree in a forest.  Your soft-drink can was once rocks.  Glass bottles were sand.  Clothing can come from a variety of resources like plants, animals and chemicals made from oil. 

 

We are using up our planets resources at a very fast rate.  If we keep going like this, we will need several planet 'earth's' to sustain us.

 

Waste does not have to be wasted.  It can have many uses, especially if it can be recycled or reused

 

What can I do?

By minimising our waste and making the most of our resources we can make a difference.

Δ    Reduce - not make rubbish

Δ    Reuse - use an item more than once

Δ    Recycle - turn waste materials into new products

Δ    Recovery - turn food waste into black gold
