What is a SWAP analysis?
SWAP, which stands for Solid Waste Assessment Protocol, is a standardised method, endorsed by the Ministry of the Environment, used by waste managers to understand the composition of waste being placed at kerbside by residents, what is being received at the landfill and who is sending the waste to the landfill.
SWAP analysis allows solid waste managers to track the changing composition of waste which allows Council to:
- understand the amount, the types of waste and who is producing the waste that is received at our landfill
- alter the existing landfill operations and inform future investments, designs and engineering of landfills. For example, how much methane will be generated in the future and the best way to capture it
- identify potential ‘problematic’ waste streams assisting us in finding solutions
- track the effectiveness of waste minimisation policies
- prioritise future waste minimisation activities and policies.
The SWAP analysis had two collection sources.
- We randomly selected 491 households and had their kerbside rubbish collections analysed.
- We surveyed 500 vehicles arriving at the Southern Landfill.
