I have changed jobs and am recieving WasteMINZ emails to my old email address (emily@haighworkman.co.nz) rather than my new one (emily.collings@gmail.com). Please can this be updated.
I wanted to ask how you think a sachet (9x6cm) made from cellulose based film, certified to AS5810 and laminated to Kraft paper would decompose in landfill?
I am trying to find information around how home compostable certified material degrades in a landfill.
Any help you can provide would be greatly appreciated.
Is there anyone on WasteMINZ who can explain why Auckland Council is going for a Landfill at the Dome Valley in spite of it being Auckland’s 2nd biggest potential source of fresh water supply, in a very sensitive catchment area that could easily pollute the Kaipara Harbour if used as a landfill.
Hi Joan
WasteMINZ represents the wider interests of over 1400 members in the waste, resource recovery and contaminated land sectors in New Zealand. I’m afraid we cannot comment on individual planning and consent decisions.

Hi Sam
Ideally anything certified compostable should be going to the system it was designed to biodegrade in. However, these materials will also breakdown in landfill. The key difference with degradation in landfills versus in composting systems is that landfills operate in the absence of oxygen, while composting systems rely on aerobic (with oxygen) degradation. As a result, degradation in landfills results in the generation of methane, rather than the generation of primarily carbon dioxide from a composting facility. At most municipal landfills methane is collected and destroyed, reducing the environmental impacts of these discharges. However, if the packaging is composted appropriately, it will reduce the overall environmental footprint of the material.

Do you collect compostable bags in Wellington?
Thank you

Hi Jennifer, you would need to check your councils guide on collections.
