Proposed extension to the Southern Landfill

With only four years left until the current stage of the Landfill is full, it’s time to talk about what we do with our waste next.

The Landfill is critical to the smooth running of our city. It’s currently where we dispose of all the treated sewage sludge from Moa Point, it takes approximately 100,000 m3 of waste per year and it funds $6 million of waste minimisation and recycling services every year.

Wellington City Council is committed to reducing waste.  Regionally our target is to reduce waste from 600kg per person per year to 400kg per person by 2026.  That still leaves us with significant waste that needs to be managed.

The Southern Landfill is currently operating in Stage 3 of its multi-stage development with the proposed extension (Stage 4) set to provide an additional 2.5 million m3 of landfill.

The Council thinks extending the Landfill is the best way forward but would like to test this assumption by looking at what alternatives are around. The alternatives that will be looked at include closing the Landfill; building a waste-to-energy plant; or using biological processes.

Looking forward, we believe that things will change, and if landfilling is still the most viable solution for now, we think it will only be an interim step towards a future without landfills.

Any solution we come up with will include our current waste diversion initiatives and be flexible enough to do more of these in the future. Currently the Southern Landfill diverts approximately 8,000 tonnes of waste from the Landfill each year. This consists of:

  • Green waste diverted to compost – approximately 5,800 tonnes a year
  • Food waste diverted to compost – approximately 1,600 tonnes per year
  • Scrap metal diversion – approximately 575 tonnes each year
  • Salvaged material from the transfer station and voluntary drop-off of material to the Tip Shop for resale – estimated 250 tonnes per year.

The Landfill also funds kerbside recycling and the free recycling drop-off at the Southern Landfill. This diverts approximately 11,500 tonnes of recyclable material from waste each year.

We’ll be seeking views from the community over the next few months. During our first information sessions we’ll be talking about the criteria we use for assessing the alternatives, and seeking your views on extending the Southern Landfill on the existing site.
