The Japanese have a word for the sense of regret they feel when something valuable is wasted: 'mottainai' (もったいない). It can be translated as “don’t waste anything worthy” or “what a waste”, and has come to represent the island nation’s environmental awareness.
Rooted in the Buddhist philosophy of frugality and being mindful of our actions, mottainai came to prominence in the post-war days of scarcity and is now handed down from grandparents to grandchildren.
But it’s also connected to Japan’s indigenous religion, Shintoism, in which nature and even man-made objects are imbued with their own ‘kami’ or spirit – meaning things have innate value and are not to be disrespectfully discarded.
Mottainai can be seen in the way Japanese decluttering champion Marie Kondo gives thanks to individual items of clothing before laying them in a pile for charity. It also explains why the country is a world leader when it comes to the 3Rs: reduce, reuse, recycle.
The term was also used by Kenyan Nobel Peace Prize winner Wangari Maathai, who founded the Greenbelt Movement, to encourage Africans to eliminate plastic waste.
Getting on top of garbage
Japan’s sophisticated waste management system has lessons for the rest of the world: everything from polystyrene to packaging for pills can be separated and recycled.
The Basic Act for Establishing a Sound Material-Cycle Society (Basic Recycling Act) came into force in 2000 – to promote the 3Rs and proper waste management – with every October designated as 3R Promotion Month.
Supermarkets now have PET bottle shredders - providing shopping tokens in exchange for plastic - that cut down on the emissions created by collections. PET resin is then used to make everything from clothes and carpets, to new bottles.
And there are apps that feature “dictionaries” to help people sort their waste, as well as alarms to remind people what to put out for collection on a given day.
There are good reasons behind Japan's motivation to tackle its waste.
In the bubble economy of the 1980s and early 1990s, production of plastics grew quickly, and so, too, did the country’s waste problem. Between 1993 and 2000, the number of plastic bottles produced tripled to more than 360,000 tonnes, according to Japan's environment ministry.

Today, Japan is second only to the US as the world’s biggest generator of plastic packaging waste per capita, according to the United Nations Environment Programme. But in a report, last year, UNEP noted,“thanks to a very effective waste management system and a high degree of social consciousness, [Japan] accounts for relatively limited leakages of single-use plastics in the environment”.
Of the 9.4 million tonnes of plastic waste produced by Japan each year, the government says only 25% is recycled, while 57% is incinerated for “energy recovery” and 18% goes into landfill or is burned.
A burning issue
Japan’s landmass is limited, so there’s little space for landfill sites, meaning garbage that can’t be recycled is often burned.
While collections vary between prefectures, in Nakano City items including food waste, unclean pizza boxes, diapers and waterproof rubber boots are collected for incineration, which generates electricity.
However, burning waste produces harmful gases, including dioxins, which were reported to be contaminating soil and even breast milk. So over the past two decades, the country has been working on improving technology to reduce emissions from incineration in order to protect people and the environment.
Between 1997 and 2003, dioxin emissions fell by 98%, according to the government.
What is Loop?
More than 90% of plastic is never recycled, and a whopping 8 million metric tons of plastic waste are dumped into the oceans annually. At this rate, there will be more plastic than fish in the world’s oceans by 2050.
The World Economic Forum has played a crucial role in connecting TerraCycle, a global waste management and recycling company, with logistics giant UPS and some of the world’s leading retailers and consumer goods companies (including Procter & Gamble, Coca-Cola, Carrefour, Tesco, Mondelēz, PepsiCo, Danone, Mars, Nestlé and Unilever) to develop and pilot a revolutionary zero-waste e-commerce system called Loop.
Loop promotes responsible consumption and eliminates waste by introducing a new way for consumers to purchase, enjoy and recycle their favorite products. Instead of relying on single-use packaging, it delivers products to consumers’ doorsteps in durable packaging that is collected, cleaned, refilled and reused, sometimes more than 100 times.
The Forum is helping the Loop Alliance bring the Loop model to cities around the world. Read more in our Impact Story.

In the run-up to the Tokyo 2020 Olympics, when all eyes will be on Japan, its drive to boost its green credentials continues apace.
There are now 26 “environmentally harmonious” certified eco-towns, according to the environment ministry. And one village has taken mottainai to another level by aiming to become 100% zero-waste by 2020.
In Kamikatsu, Akira Sakano set up the Zero Waste Academy. Although 80% of the village’s waste is kept out of incinerators and landfill, Sakano told the World Economic Forum that manufacturers need to do more to help them reach 100%.
“Products need to be designed for the circular economy, where everything is reused or recycled. These actions really need to be taken to businesses and incorporate producers, who need to consider how to deal with the product once its useful life has ended.
“It’s important, no matter the obstacles, to keep striving to achieve the 100% goal. It’s important that world leaders now take their turn to make circular economy happen,” Sakano said.
