The Shire of Dardanup has rethought the way it recycles in an effort to keep costs down for residents.
The shire has negotiated a new deal with contractors Suez by tying future rises in costs to the community's recycling performance.
The new agreement comes after China's ban on many categories of foreign waste last year, plus falling commodity prices.
Dardanup shire president Mick Bennett said the community needed to improve its recycling habits.
"Our level of contamination goes up, the amount Suez will charge us per tonne of recycling collected goes up - but if we can get our rate of contamination down, so too will the price they charge us," he said.
"We have three months to make a difference and save ourselves some money."
Suez and the shire will conduct an audit of recycling contamination levels in September to determine future price levels with random audits occurring soon to gauge progress.
Cr Bennett said the shire would be conducting a broad community education campaign to help residents improve their recycling habits and reduce contamination.
"We've already seen that our community is very responsive to information on this topic and open to change," he said.
"In the 2017/18 financial year, we recorded a doubling in the amount of recyclables collected for the first time in four years following our BYO bag campaign and circulation of associated information.
"In the same time period, the amount of domestic refuse collected and taken to landfill recorded a significant drop.
"That shows us we are recycling more, we now just need to do it better."
To learn more about how to recycle correctly the shire directs locals to check the guides at the back of their waste calendar, which will be delivered with rates notices and a magnet to attach to the fridge.
