There’s no rubbish truck in Kamikatsu.
As a substitute, the Japanese city’s 1,400 residents take their waste to the native recycling centre, or “Gomi station”, and type it themselves into certainly one of 40 completely different classes.
There are assortment bins for nearly all the things: toothbrushes, wood chopsticks, mirrors, mercury thermometers, button batteries, ball-point pens and disposable chopsticks. Reusable objects go to the Kurukuru store, the place anybody can take them house.
The last word purpose is “zero waste” and the meticulous sorting contributes to an 80% recycling charge.
This mountainous city on the island of Shikoku could also be an outlier however as Victorians type their waste into 4 kerbside bins – essentially the most in Australia – households in some international locations recurrently cope with 5 or 10 completely different recycling streams.
Separating waste can enhance the standard of recyclable supplies and scale back contamination however are extra bins higher for the setting?
Kerbside wheelie bins have been utilized in Australia because the Eighties.
Over time, new bins with variously colored lids have been added; they embrace commingled recycling (yellow), organics (inexperienced), glass in Victoria (purple), and paper and cardboard for some councils in New South Wales and South Australia (blue).
In accordance with the most recent knowledge, native governments accumulate about 9.9m tonnes of waste through kerbside bins annually, made up of 6m tonnes of garbage, 1.8m tonnes of recycling and 2m tonnes of organics.
“Many councils have a waste hotline as a result of bin assortment is one thing that communities actually care about,” says Amelia Leavesley, who researches waste on the College of Melbourne.
Kerbside assortment is one a part of a posh system. For recycling to work effectively, supplies must be recyclable within the first place, Leavesley says, earlier than they are often separated by households. Councils gathering the waste want entry to infrastructure, like supplies restoration services, and there must be market demand for the ensuing recycled supplies.
Along with wheelie bins, states and territories have added container deposit schemes, drop-off factors the place folks can declare 10 cents for every eligible drink bottle or container. South Australia was the primary to take action in 1977, and Tasmania the final in 2025.
How do Australia’s kerbside bins evaluate globally?
Aside from Victoria, which goals to make 4 providers commonplace for each family, most of Australia operates with two or three kerbside bins and a container deposit scheme.
However that pales compared to sorting techniques elsewhere on the earth.
Nationwide waste knowledge exhibits recycling charges for “municipal strong waste” – waste produced by households and a few small companies – are a lot increased in Japan (79%) and Germany (69%) than Australia (44%).
Excessive recycling charges in lots of European international locations are underpinned by their longstanding use of separate assortment techniques, in keeping with environmental consultants Eunomia.
In Germany, family waste is separated into 5 principal classes – natural (or “biowaste”), paper and cardboard, glass (sorted by color), metallic and plastic, and residual waste.
Home assortment operates alongside the “world’s largest and highest-performing deposit return system”, which has achieved a 98% return charge on single-use drink containers, in keeping with one firm that manufactures reverse merchandising machines.
“There’s additionally a very sturdy tradition round recycling in Germany,” says Leavesley. “Persons are actually keen about ensuring there’s clear, separated merchandise.”
In Wales, some houses have as much as 10 separate bins, in keeping with the BBC. Insurance policies designed to realize the purpose of zero waste by 2050, together with recycling, have elevated seen the nation’s municipal waste recycling charge from about 5% in 1999 to 68% in 2025.
As Victorians acclimatise to 4 bins, residents of Cardiff, the capital of Wales, will quickly be requested to type their waste into eight completely different streams: plastic and cans, mushy plastic, paper and cardboard, meals waste, glass, backyard waste, common garbage and nappies.
Huw Irranca-Davies, the deputy first minister of Wales, says: “Recycling is now part of who we’re as a nation.”
Are extra bins really higher?
There are trade-offs to having extra bins, says Joe Pickin, the director of environmental consultancy Blue Setting. “I don’t assume anyone’s bought the proper system,” he says.
Extra stream separation may lead to cleaner, higher-quality supplies but additionally require additional collections, extra vehicles on the street, and better prices.
Even in Australia, options that work within the metropolis is probably not cost-effective for a rural space. “We’ve bought an enormous nation, and it will get laborious to do recycling in some circumstances, as a result of the transport prices begin getting actually excessive,” Pickin says.
There are various different elements that affect the design of kerbside collections – just like the density of neighbourhoods, demand for recycled supplies, and whether or not any residual garbage leads to landfill or an incinerator. Introducing a brand new recycling service additionally takes time for folks to get used to.
“It’s a generational change,” says Pickin. “It’s not one thing you possibly can simply do in a 12 months.”
‘We can’t recycle our method out of a disaster’
A report by the UN setting programme estimates that greater than 2bn tonnes of municipal strong waste is generated throughout the globe annually.
“It needs to be emphasised that recycling will not be the last word purpose of waste administration: it’s all the time higher to scale back waste by stopping it within the first place, or reuse supplies that may in any other case change into waste, than to provide waste after which recycle it,” the report says.
Cip Hamilton, the plastics marketing campaign supervisor on the Australian Marine Conservation Society, says the issue begins with producing an excessive amount of plastic and different supplies.
Plastic air pollution is likely one of the biggest threats to Australia’s marine life, she says. “It’s vital that we work on upstream measures to show it off on the faucet. Plastic air pollution happens at each stage of the life cycle, together with extraction, manufacturing, transport, use and disposal.
“If we solely concentrate on the downstream measures, then we received’t scale back the quantity of plastic air pollution that’s ending up in our surroundings.
“We can’t recycle our method out of a disaster pushed by overproduction.”
Persons are understandably annoyed by the layers and layers of packaging they encounter when attempting to navigate easy day by day duties like going to the grocery store.
“What we want is much less packaging and simplified codecs,” Hamilton says. “We shouldn’t should have a level in materials science to know what goes the place.”
