Getting to zero: the Japan town trying to recycle all its waste

Plastic, paper, metal? In Japan's Kamikatsu, sorting rubbish isn't that simple. Residents face a mind-boggling 45 separate categories for their garbage as the town aims to be "zero-waste" by 2020.

And that's not all: there isn't even trash collection. The 1,500 residents of the town in western Japan have to transport their themselves to a local facility.

"Yes, it's complicated," said Naoko Yokoyama, a 39-year-old resident who had brought her trash to the town's waste centre.

"But I have become more environmentally conscious since I moved here a year ago," she told AFP.

The categories cover everything from pillows to toothbrushes as the town aims to recycle all its waste, sending nothing to incinerators, by next year.

The process can be onerous—not only are there dozens of separate categories, but items like and bottles must be washed and dried to facilitate recycling.

At the town's waste facility, there are dozens of different boxes for each category. If the parts of an item fall into different categories for recycling, residents are expected to take them apart and send each bit to the right container.

One man who had brought in a shelf had to use a hammer to prise the wood from the metal, while elsewhere workers chopped up a thick, long rubber tube so it would fit into a sorting box.

Many parts of Japan already require separation of rubbish, but most areas have just a few categories, with the bulk of household waste going to incinerators.

'Let's recycle'

Kamikatsu was not much different until an ultimatum: in 2000, the town was ordered to shut down one of its incinerators because it no longer met stricter emissions standards.

That left the town with just one incinerator that couldn't handle all of Kamikatsu's waste, and there wasn't enough money for a new one or to pay a neighbouring town for use of theirs.

"We thought, 'If we can't burn waste in the town, then let's recycle.' It's cheaper to recycle waste than burn it," said town official Midori Suga.

Kamikatsu is already close to achieving its goal, recycling about 80 percent of the 286 tonnes of waste it produced in 2017, far more than the national average of 20 percent.

The remainder, like most waste in Japan, is incinerated, as the country's mountainous terrain considered unsuitable for landfills.

The nation produces less general waste per person than most developed countries, but it generates more waste per capita than anywhere except the United States.

In the past, some plastic was exported for recycling, particularly to China, but a ban by Beijing on imports has left plastic recyclables piling up in parts of Japan.

Still, not all residents think the initiative could work elsewhere.

"It works because we're only 1,500 people here," said Yokoyama, who moved from Kyoto.

"It would be difficult in a big town with a larger population," she added, because authorities would struggle to enforce it.

Reduce consumption

But other residents say the policy is just common sense.

"I understand it's convenient to just burn waste," said 71-year-old local Saeko Takahashi, as she washed milk cartons and tied newspapers together.

"It's better to recycle, it's such a waste otherwise," she explained.

She uses a compost bin for such as fish and meat and throws vegetable waste directly into her garden.

"Food lasts longer when it's shipped in plastic packaging. So it's not all bad, but multiple layers of plastic aren't necessary," added Takahashi.

Kazuyuki Kiyohara, manager of the waste centre, said plastic makes up the majority of the residents' waste—and despite the scheme there has been little reduction in consumption.

"Our lifestyle depends mainly on plastic," the 38-year-old said, adding: "Consumers can reduce plastic waste to a certain extent, but we'll still have waste if producers keep making plastic products."

In 2018, Japan's government unveiled a proposal to tackle plastic waste, with the goal of reducing the 9.4 million tonnes produced by the country each year by a quarter by 2030.

The plan proposes that retailers should charge for plastic bags—a measure already widely adopted around the world—but that isn't expected to come into effect before 2020 and other types of won't be covered.

Town official Suga said even Kamikatsu will struggle to achieve zero-waste without stronger efforts to reduce consumption.

She said: "We have made efforts to achieve zero incineration and zero landfill disposal goals, but it's not enough."

She explained: "We shouldn't focus just on how to dispose of trash. We need to come up with policies that prevent the production of waste."

Good for them.
So, why can't WE try doing this?
So far, were I am in the UK, all I see is some meaningless token gestures done just to try and win a few more votes. I'm not even allowed to put about half the types of plastics in the recycling bin and there's nothing for food waste.

idiots. virtue signaling idiots. your trash isn't hurting anyone or thing. go fix China, India, Indonesia and Malaysia. when you're done there you can take on Russia and all of Africa.

Well done Kamikatsu. I wish we could be like you in our town. Since China banned waste imports our waste is being illegally dumped, and recycling is just a joke. We need to reduce plastic packaging drastically, or pay more for our packaged goods.

The world is choking in plastic and Kamikatsu town is showing us how to take proper responsible action - local action.

As a scientist I am interested in hearing the other side of the story, which this story fails to consider. When households are required to prepare their trash for recycling, then they use resources such as (1) time to separate into xx categories, (2) using water and natural gas (water heating) and soap to clean bottles, cans, lids, and other containers so the material can be recycled, (3) each individual is required to take their own trash in their own cars (using gasoline or electricity) to the recycle center thereby reducing efficiency. A study should be done to compare such an approach.

Plasticated

There are simple ways to cut down on plastic
Stop packing 6 apples in plastic containers
We can put our apples in a paper bag
Any fruit
Like
Grapes
Tomatoes
Cherries
Can be put in paper bags
For shredded wheat are packaged in paper wrappers in a cardboard box
SUGAR, for time immortal has and is packaged in its paper bag
Take bread, always in paper bags
The potential to cut out plastic in packaging is there for all to see
For this mindset of plastic is to not put items in plastic in the first place

So simple it blows the cobwebs from our minds
