The various scenes where we spend our day to day life without much
thought are actually deeply tied to every environment.
Let's reflect on a day from the perspective of "things" that support our lives, to see how our actions and choices affect the environment.
Scenes of daily life
Disposing of garbage
How much garbage does Shinagawa City produce every day?
Shinagawa City produces about 270 tons of garbage every day, including garbage from homes, companies and offices, and various stores. That amounts to about 700 grams per resident.
Looking at a breakdown by source, household garbage accounts for about 53%.
Looking at the types of garbage, about 70% of all garbage from the city is burnable garbage, and about 43% is food garbage.
Good morning. I'm garbage. Please listen to my diet problems.
I only slimmed down well at the beginning.
As you can see, I seem to have plateaued.
At this rate, landfills for garbage may be full in about 50 years...
*As of 2018: Landfills of Tokyo Metropolis
Actually, there are many things that get thrown away as garbage which we can reuse as resources. Can you think of ways to reduce the amount of garbage you throw away and increase the amount you reuse?
Change of clothes
How many clothes do you have that you don't wear anymore?
Japan is overflowing with clothes!
98% of clothes sold in Japan are imported from abroad.
Clothing prices are getting cheaper every year, and fashion trends change very quickly, causing concern about mass production, mass consumption, and mass disposal.
Japanese people tend to buy more clothes than they get rid of, so on average each person in Japan has 25 articles of clothing that they have not worn even once in a year.
Good morning! I'm a shirt.
I saw information saying that we put a burden on the environment...
It seems that when we clothes are made, we consume a huge amount of water and emit a huge amount of CO2... It pains me to think of this, because we were made to benefit people.
However, we clothes work for a surprisingly short time.
After that, most of us are put in the garbage and sent to incinerators or landfills.
Now that I'm out in the world, I want to be useful for a little longer. I'm fine working as second-hand clothes.
What comes off clothes when you do the laundry?
Dirt isn't the only thing that comes off clothes when you do the
On average, we drain about 250 liters of household wastewater per person per day. About 10% of dirt in this wastewater is from laundry.
Microplastic fibers that washed off synthetic fibers chemically synthesized from petroleum (acrylic, polyester, etc.) also mix into wastewater from laundry. These fibers are so small that they can flow right through sewage treatment plants, and into rivers and the sea.
*Household wastewater: Wastewater from daily life, including kitchens, toilets, baths, and laundry.
*Microplastic fibers: Extremely small pieces of fiber that strip off synthetic fiber fabric in the wash. They can have an effect on the ecosystem of the sea.
Good morning! They say laundry is polluting the water of the Earth.
What a shock!
Nearly 10% of dirt in household wastewater is caused by wastewater from laundry. What should we do about this?
*BOD: An index of the degree of water pollution. The higher the pollution level is, the higher the BOD value will be.
I want you guys on the washing side to think, not the position of the laundry to be washed.The fact that laundry detergent is the biggest cause.
Also, it seems the microplastic fibers that flow off of us every time we get washed hurts creatures living in rivers and the sea. We have to do something about this too!
What cool vehicles will there be in the future?
How much CO2 is emitted by transportation such as cars, ships, and
Total CO2 emissions in all of Japan are about 1.1 billion tons per year. Of this, 18.6% are emissions from the transportation sector, including cars and ships.
Within the transportation sector, cars emit the most, accounting for 86.1% of the transportation sector and 16.0% of total CO2 emissions.
Good afternoon. I'm a car.
I'm thinking of getting a makeover.
The amount of CO2 emitted to carry one person one kilometer is 2.3 times as much for cars as for buses. Cars also emit INOx and SPM. That really gets me thinking.
*NOx: The general term for nitric oxide (NO), nitrogen dioxide (NO2), dinitrogen tetroxide (N2O4), etc. NOx is one of the substances that cause air pollution.
*SPM (Suspended particulate matter): Particles with diameter of 10 μm (0.01 mm) or smaller that float in the air. SPM is harmful to the lungs and trachea.
It's cool to drive fast with the engine revving.
That's my style as a car, but it would also be cool to become an electric car or hydrogen car and aim to reduce my environmental burden.
Have you thought of anything to do with vehicles?
Japan has the lowest food self-sufficiency rate among developed
The food self-sufficiency rate is the ratio of food produced in a country to food consumed in that country.
Calculated on the basis of energy (calories) obtained from food, Japan's food self-sufficiency rate peaked in 1965 at 73%, but bottomed out in 2020 at 37%, the lowest level of any developed country.
Without imported food, Japanese dietary life would not be possible.
Good afternoon. We are food.
Some of us come from very far away.
Do you know the term "food mileage?" It is the product of the weight of food multiplied by the distance it is carried. Japan imports a lot of food from distant foreign countries, so of course Japan's food mileage is high. In fact, it is the highest of any developed country.
Food is carried to Japan from abroad by ship or by plane, and the longer the distance food travels, the more CO2 is emitted.
What do you think we should do?
What snacks do you like?
What is palm oil?
Palm oil is the most commonly used vegetable oil in the world, made from oil palms grown in tropical regions.
About 700,000 tons of palm oil are consumed in Japan every year. About 80% of this oil is used for food products such as instant noodles and snack foods, while the rest is mostly used for soaps and detergents.
85% of the world's palm oil is produced in the countries of Indonesia and Malaysia in Southeast Asia.
Good afternoon. I'm candy.
I heard that troubling talk about palm oil...
Palm oil is used to make candy. It seems that we are cutting down and burning tropical rainforests to make oil palm plantations where we can source that oil.
When a forest burns, tons of CO2 is emitted, and the creatures that live there disappear.
You might be thinking "Stop using palm oil and use another oil!" but doing that would require even more land.
Even children are made to work on oil palm plantations. It's so sad.
Are you flushing everything down the drain?
The kitchen is the source of household wastewater that produces the
On average, we flush about 250 liters of household wastewater per person per day. About 40% of the dirt in that wastewater is caused by dishwashing in the kitchen. This is the largest ratio of dirt, exceeding the dirt in bath wastewater or toilet wastewater.
Sources of dirt in kitchen drainwater include cooking oil, seasonings, leftover food and drink, as well as detergents.
*Household wastewater: Wastewater from daily life, flushed from kitchens, toilets, baths, laundry, etc.
Good evening. We're the used seasonings and detergents. I guess you
Sure, we're not very good for the environment. But it's the people who are responsible for this.
Isn't the oil used by people and the seasonings that have been put out too much drained directly into the drain?
Many people use more detergent than they really need to, don't they?
It takes a whole lot of water to dilute us until water quality is good enough for fish to live in. What do you think of that?
*BOD: An index of the degree of water pollution. The higher the pollution level is, the higher the BOD value will be.
How much water is necessary to clean a single drop of water?
Lift up slowly to check.
What is shampoo made of?
Just what are chemicals?
PET bottles, paints, living trees, and everything else around us is made of chemicals.
Chemical substances include those already found in nature, and those produced by humans. By skillfully exploiting the properties of these chemicals, we are able to make the convenient lifestyle that we enjoy today.
However, misusing or disposing of chemicals without proper treatment can cause a negative impact on humans, other animals, and plants.
Good evening. We're shampoo and conditioner.
We give you wonderful hair.
These are the ingredients of shampoo. Half is water.
A surfactant removes dirt, so it is the key ingredient of shampoo.
However, some surfactants bring health concerns.
Conditioner contains ingredients that protect hair made easily damaged by shampoo, and keeps hair moisturized.
However, using either shampoo or conditioner too much can impact your body, so don't you think it is important to use the right amount?
Centerpiece of the home
Do you leave your TV on all the time?
Which home appliances use the most electricity?
About 40% of Japan's CO2 emissions come from power generation to produce energy.
Power is generated according to demand for electricity, and about 30% of electricity produced Japan is consumed in homes.
Home appliances that consume a lot of electricity include refrigerators, lights, televisions, and air conditioners.
In particular electricity consumption tends to increase in the hours from evening to night.
Good evening. I'm a television.
Thank you for watching so often. But sometimes you leave TV on.
The best thing you can do at home to reduce your CO2 emissions is to save power. That includes choosing home appliances with good power saving performance. Performance of air conditioners has improved greatly.
Televisions used to be big and bulky, but since they became thinner, their power consumption has dropped by more than half.
Even refrigerators consume less power than you would expect. But because they run all year without stopping, they consume the most electricity among home appliances. Thanks for your hard work, fridges!
What else can we do to reduce CO2 emissions?
Please make good use of us home appliances, who are working hard all the time.
Ideas for better living
The three Rs are decisive factors for less waste
Start with Reduce!
Reduce means making less garbage in the first place.
For example, that includes draining water from food waste.
About 80% of food waste is water. Draining water reduces the volume of garbage, and helps prevent rotting and foul odors.
In addition, you can...
・Only buy as much food as you need, and use it all.
・Buy products that can be refilled.
・Bring your own bags and bottles.
These are also effective means of reducing waste.
Reuse and recycle
Before you make garbage...
Reuse means using the same product over and over again.
You could give it to someone familiar, put it up for sale in a thrift store or flea market, or use the Internet to find someone who wants it.
Recycling means turning used products into resources for making new products.
Some neighborhood or resident associations collect resources as groups.
Wearing clothes carefully for a long time
helps to protect the environment!
Some clothing products make an impact on the environment in their manufacturing process.
For that reason, you should wear your clothes carefully for as long as possible.
Here are important points to do that!
・Choose quality clothes you can wear for a long time.
・Care for and clean clothes appropriately for each fabric
・Mend your clothes (repairs, etc.)
You can also choose organic clothing that is made with consideration for the environment.
Used clothes are fashionable!
Enjoy reusing clothes!
Clothes that you don't need anymore may be clothes that other people want to wear.
The opposite might also be true.
Here is how you can reuse clothes without wasting them!
・Give them to or get them from acquaintances.
・Sell or buy them on the Internet or at flea markets.
・Sell or buy at thrift stores or used clothing stores
A growing number of people buying used clothes at reasonable prices and enjoying fashion.
Just adding more detergent does not
guarantee that dirt will come off better!
Detergent is the greatest cause of water pollution among contaminants contained in laundry wastewater.
There is a proper amount of detergent to use. Just because you use a lot of detergent do not mean that dirt will come off better. Make sure to measure the proper amount of detergent so that you do not use too much.
Don't let microplastic fibers escape!
Microplastic fibers are very fine fibers made of plastic. For example, if you wash clothes made of synthetic fibers such as polar fleece, fibers will slip through the machine and into the wastewater, so you should those clothes in special laundry nets. Using natural materials such as wool and cotton will help prevent this from happening. When you buy clothes, make sure to check what materials were used to make them.
*Synthetic fiber: A fiber chemically synthesized from raw materials such as petroleum.
Take a ride on a
fuel cell bus that doesn't emit CO2!
Fuel cell buses are driven by motors that run on electricity generated using hydrogen and the oxygen in the air. When generating electricity, the only other thing they produce is water. They are clean vehicles that do not emit CO2 or other air pollutants.
The Tokyo Metropolitan Government is running a project to promote introduction of fuel cell buses. Some of these buses even run in Shinagawa City. Try riding one of these buses, and you'll find they are very quiet when running.
Bicycles are good for the environment and your health!
Bicycles do not emit CO2, and are a great way to exercise.
Have you ever wanted to ride a bicycle, but don't have yours with you? In that case, you should try bicycle sharing.
Shinagawa City is promoting a bicycle sharing business. It is a convenient system that allows you to rent and return bicycles anywhere in the service area.
How can we increase our food self-sufficiency rate?
If we choose domestically produced ingredients, we can raise our food self-sufficiency rate. However, circumstances such as prices make it understandable that we often choose imported products.
Why not reconsider what you eat?
For example, you could eat rice more often. Rice can be covered 100% with crops grown in Japan, helping to increase our food self-sufficiency rate.
Traditional Japanese meals may be the key to solving this problem.
"Bentos locally produced for local consumption"
Working to reduce food mileage!
The photograph is of a "bento locally produced for local consumption" made using only local ingredients by a bento shop in Kumamoto.
The graph is a comparison of food mileage when using only domestically grown ingredients and when using imported ingredients.
Bento locally produced for local consumption using seasonal ingredients, such as fresh vegetables and fish. It looks delicious.
Let's learn how the food we eat is made
For example, if you try to grow summer vegetables in winter, it will take a lot of energy to heat them inside a greenhouse or other structure. If you use herbicides to save effort weeding, it will contaminate the land and water.
The same food can have different effects on the global environment depending on how it is made.
In order to choose foods that have a low environmental impact, it is important to know how they are produced.
Choose foods that use sustainable palm oil
There is an international organization called RSPO, which aims to promote production of sustainable palm oil, taking into consideration the natural environment and work styles.
When you get food, look for the RSPO certification mark.
It is also important that you communicate your feelings as a buyer by contacting food manufacturers and telling them to "Make products with the RSPO mark." There is also "Fair Trade" certification, indicating products made with consideration for the environment and work styles.
*RSPO: Roundtable on Sustainable Palm Oil
6 ways to reduce dirt in wastewater from your kitchen
1) Only make and serve as much as you intend to eat.
2) Throw away deep frying oil as little as possible, and use it for stir-fry or other food instead.
3) Wipe off oil before washing dishes.
4) Use a washing tub to wash dishes, and dilute a proper amount of detergent in water before using it.
5) Use water in which you washed rice to water plants.
6) Catch fine vegetable scraps in a drain bag or a triangular sink tidy.
River purification efforts are underway!
The Meguro River and Tachiai River used to have the worst water quality among rivers in Tokyo. However, their water quality has been improved by myriad efforts. Sludge was scraped off and obstacles such as piles and chunks of concrete were removed from riverbeds. High-concentration oxygen-dissolved water supply devices were put into operation. Groundwater and reclaimed water were discharged into rivers.
In the case of the Tachiai River, awareness of river purification was improved through initiatives such as sending residents of Shinagawa City to beautify the environment by cleaning rivers and roadsides.
Be careful not to overuse
body soap and shampoo!
Body soaps, shampoos, and bath cleaners can have a negative impact on living things if they are not fully treated at a sewage treatment plant.
While they are properly treated at sewage treatment plants, if the volume is high, this places a burden on the treatment plant.
Use the proper amount shown on the label, and be careful not to use too much.
If you use too much, it may actually be more difficult to remove dirt.
Check ingredients and choose ones
with less impact on the environment
Detergents, which also includes body soaps and shampoos, use "surfactants," the ingredients that remove stains.
There are many types of surfactants, some of which are designated as "chemicals potentially harmful to human health and the ecosystem."
Check ingredients and precautions shown on the label, and choose a product that does not burden the environment.
