Recycling Bin Audit Results


We're taking a close look at recycling.

The Council are taking a closer look at kerbside recycling bins through spot-checks following a spike in recycling contamination early in 2020. The aim of the exercise is to see first-hand the items causing contamination, and let residents know where they’re going wrong.

Recycling bins contaminated by rubbish and other non-recyclable items is threatening the viability of the collection service, and is hitting ratepayers in the wallet. Between October 2020 and April 2021 the cost to ratepayers for landfilling contaminated recycling is up to $307,000 with 253 truckloads being rejected because of dirty recycling.

If we emptied a heavily contaminated bin into the recycling truck, or several bins with a few contaminants inside, it all adds up and would contaminate the entire load sending it to the 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.
