Some WA councils say an energy deal means they must resist government pressure to introduce a third bin. 

Perth councils have rushed to introduce new Food Organics, Garden Organics (FOGO) bins after the state government vowed to roll out the initiative metro-wide by 2025 several years ago.

However, some councils in Perth's outer suburbs are pushing back, saying they are focused on WA's first waste-to-energy plant instead. 

Eight Perth councils signed on to supply rubbish for the Kwinana waste-to-energy plant in a deal that pre-dates the WA government's commitment to FOGO. 

The City of Gosnells, in Perth's south-east, is among that group. 

Gosnells Mayor Terresa Lynes says waste-to-energy is a lower cost option.

“[Waste-to-energy] has been widely used all over the world … so I think it's exciting that we've got something that's happening in WA,” she said.

“We're actually trying to keep our rates down here in the City of Gosnells, not implement new services that are going to create the same thing as what we're doing - getting rid of waste.”

Analysts say that a two-bin system along with waste-to-energy would cost the average household $190 a year, but adding a FOGO bin to the mix would drive the cost to over $240 a year.

“I'm worried about bringing in a FOGO system because what are we going to do with the FOGO? There just isn't the infrastructure here at the moment or the demand,” Cr Lynes said. 

There is also concern that some of the WA council’s that have introduced FOGO have been left with piles of organic material that has not been used.

The cities of Mandurah, South Perth, Armadale, Canning, Kwinana and the shires of Serpentine-Jarrahdale and Murray all signed up to the 2015 deal to provide rubbish to the Kwinana Waste to Energy project each year.

The plant is intended to be up and running by the end of next year, with the capacity to produce enough energy to power 50,000 households.

The WA Government’s waste plan lists waste-to-energy as the “least-preferred recovery option”. 

WA's Environment Minister Reece Whitby says he will continue pushing for councils to roll out a FOGO bin alongside waste-to-energy by 2025.

“There's material residual waste all over Perth, the South West, and the Peel area that could actually fulfil that obligation [to waste-to-energy] so it doesn't have to be with these particular councils,” he said.
