Mindarie Regional Council has closed its resource recovery facility for 14 weeks to replace composters that developed cracks soon after it opened in 2009.
The facility converts household waste from the cities of Joondalup and Wanneroo to compost.
A MRC statement said the composters had been temporarily repaired to allow production to continue while new machines were designed and built.

READ NOW"The installation of the new composters is now taking place, closing the resource recovery facility for an expected 14-week period," it said.
"While the facility is closed, the waste will be diverted to the Tamala Park landfill site."
MRC chief executive Brian Callander said the facility, when operating, helped divert waste from landfill, with more than 50 per cent of waste it received from its seven member councils diverted.
"The composter replacement should see the resource recovery facility through until the end of its operational life," he said.
"During the shutdown the contractor will undertake maintenance of other parts of the plant, minimising future lost production time.
"The MRC has ensured that member councils or their ratepayers will not be financially disadvantaged as a result of the shutdown."
MRC has advised residents to use their bins as usual during the shutdown residents, with no change to collection of both recycling and general waste bins or bulk verge waste.
