A Melbourne council has declared war on glass in recycling bins, saying it contaminates other materials and and prevents them being recycled.
Five months after implementing its ban on glass in general recycling and providing residents with a glass-only bin, Yarra City Council says it has achieved significant results.
Project Officer Joe Agostino says the trial involved 1,300 Abbotsford households, which were given a new bin and an ultimatum: separate your glass or we won’t pick up your recycling.
Council also reduced weekly garbage collection from once a week to once a fortnight and introduced two new bins.
Residents in the trial area now get mixed household waste, recycling and glass picked up once a fortnight, and food and green organic (FOGO) waste collected once a week.
“The number one focus was getting the glass out of the comingled recycling, and getting clean glass and clean recycling,” Cr Agostino told Government News at Waste Expo Australia after providing an update on the trial.
“Glass is a contaminant the way we’re picking it up at the moment. If you look at the co-mingled system, you’re mixing everything in – it goes into the bin, into the truck and gets compacted. Then it goes to a processing plant where it gets crushed and it just contaminates the rest of the material,” he said.
“So by taking the glass out, we were trying to achieve two things – how much glass could we recycle for new glass, and what effect would that have on the other co-mingled recycling.
“The FOGO was purely getting organics out of the landfill stream.”
Council has been thrilled with the results.
“The results have been good,” Cr Agostino says. “It took us a while to get glass out of the co-mingled bin, but we’re now down to about 0.2 of one per cent, which is negligible.”
Forty per cent of glass was diverted from mixed bins – the equivalent of 3,500 tonnes per year – and the separate glass recycling resulted in up to 95 per cent of glass being recycled, compared to 45 per of glass in co-mingled bins, Cr Agostino said.
Forty-three per cent of food and green waste, or the equivalent of 6,500 tonnes per year, was diverted from landfill as a result of the FOGO initiative.
Cr Agostino admits the trial was “shock therapy” for some members of the community but firmly believes that recycling bins must be respected.
“The focus for us was, can we change human behavior? Can we reduce the amount of waste that we generate? The second focus was, can we improve the quality of all the recycling material and extract as much resource as possible?”
He says Australia made a huge mistake when it adopted mixed recycling.
As far as Yarra Council is concerned, there’s no going back now, he says.
“We’ve just got to admit we got it wrong. Let’s just get back to collecting it separately,” he says.
Yarra City Council was not affected by the recent decision of recycling operation SKM to stop accepting recyclable materials. Kerbside recycling is currently transported to Polytrade in Dandenong for processing.
