Bankstown, Australia tested a range of options for reducing waste contamination.
Since the introduction of the household recycling service, councils had experienced challenges in helping residents understand how to Recycle Right.
To address this, Bankstown City Council commenced work on a major project to reduce contamination rates in yellow recycling bins to below 10%.
