Recycling Bin Audit Results


We’ve been around the District and checked over 8,000 recycling bins since mid-October in an effort to prevent recycling being sent to landfill.

It's been worthwhile, as we've been able to see the items that are causing contamination and let people know so that they put the right things in the right bins.

In the first week of the checks, 24% of bins were too contaminated to collect. We provided these residents with information about what can and can't be recycled, and after follow up checks, contamination dropped to just 8% resulting in an overall improvement of 66%.

Contamination levels in other spot checked areas continue to be high. So far, 1,415 yellow bins were found to be contaminated with food, rubbish, soft plastics, dirty nappies and sanitary items, clothing, broken toys and other dirty or non-recyclable items. These bins were left uncollected so that they didn’t contaminate the recycling truck, and we left information with the residents to let them know what items can be accepted for recycling.

If we emptied a heavily contaminated bin into the truck, it would contaminate the entire load and would have to be sent to landfill.

Check out the stats in the 'Weekly District-Wide Contamination Rates' section below to see how many truckloads of recycling have been sent to the landfill because they're too badly contaminated to be processed for recycling. It also shows the additional cost to ratepayers.
