Green Action Challenge × News from Yeonhui Youth Center

A new neighborhood's first cleanup record,
in front of three schools

This issue tells the story of a participant from Yeonhui Youth Center

September 28 to October 1, 2026

Hello! Here is news from Green Action, part of the World Cleanup Day award program.
I'm Kwonseon Yoo, the editor.

This story comes from Baekseok-dong, Incheon. From September 28 to October 1, one participant from Yeonhui Youth Center went out three times and picked up 243 pieces of litter on the roads in front of three schools. The apartments and schools here are new, so this is the first cleanup record for these roads.1

Three things the data told us
1. Litter piled up again after cleaning
The road by the bus stop (Zone A) was cleaned on September 28, but three days later, cigarette butts had piled up again.
2. Traces of things left all at once
At one spot in front of the school (Zone B), 20 cans and 20 pieces of Styrofoam were found all together.
3. Zero inside the school no-smoking zone
None of the 139 cigarette butts were found within 30 meters of a school boundary.
In this issue
1  Litter spots forming in a new neighborhood
2  Noticing them before they become habits
3  Cans and Styrofoam left in one spot
4  What each zone needs

One. Our neighborhood map

Even a new neighborhood is starting
to get spots where litter piles up

The taller the bar, the more litter was found there. The bar color shows the most common type of litter.

The three zones from above

Here are the three zones seen from above. Litter was left differently in each zone. We drew a simple example for each type.2

Map seen from above. The three zones (A Hanjung-ro by the bus stop, B Litter pile in front of the school, C Road between the school and the apartments) are drawn as colored shapes, and litter records are shown as dots

Dots = litter records (bigger = more items)
Zone size: A about 0.5 ha, B about 0.5 ha, C about 0.7 ha
School boundaries based on OpenStreetMap

Zone A type: Roadside where people wait for the bus
Hanjung-ro by the bus stop about 0.5ha, 70×83m
Zone A, type “Roadside where people wait for the bus”: a line drawing of how litter gathers at Hanjung-ro by the bus stop
A road about 60 meters from the Baekseok Middle School intersection bus stop. Out of 60 pieces of litter, 50 were cigarette butts.
Where did the cigarette butts that piled up again in three days come from?
Zone B type: Spot where things were left all at once
Litter pile in front of the school about 0.5ha, 70×79m
Zone B, type “Spot where things were left all at once”: a line drawing of how litter gathers at Litter pile in front of the school
A road about 50 meters from the Baekseok Middle School boundary. 20 cans and 20 pieces of Styrofoam were piled up in one place.3
Are the cans and Styrofoam from the same event?
Zone C type: New road before habits set in
Road between the school and the apartments about 0.7ha, 128×57m
Zone C, type “New road before habits set in”: a line drawing of how litter gathers at Road between the school and the apartments
A road between Incheon Handeul Elementary School and an apartment complex. Out of 56 pieces of litter, 44 were cigarette butts.
Why were cigarette butts left on the road between the school and the apartments?

Two. A brand-new neighborhood

If we notice them early,
we can change them first

In a new neighborhood, the places where people stop and hang out are only just being decided. If we find litter spots before they become permanent, we can be the first to suggest what is needed, like trash cans or signs.

The area within 30 meters of a school is a no-smoking zone
Since August 17, 2024, smoking has been banned within 30 meters of elementary, middle and high school boundaries. All the cigarette butts picked up in Baekseok-dong were found on roads outside that line.

Three. What did we pick up?

Cans and Styrofoam
left in one spot

Cigarette butts were the most common with 139 found, followed by 30 cans and 20 pieces of Styrofoam.

139 (57%)
Cans
30 (12%)
Styrofoam
20 (8%)

Counted from the app: each time a piece of litter was picked up, its type was tapped in the app

Most of the cans in Baekseok-dong came from one spot in Zone B.4

Shall we figure it out together?
How did 20 cans and 20 pieces of Styrofoam end up in Zone B? Look at the clues and talk about it with a friend.
Clue 1 The cans and Styrofoam were found 15 meters apart
Clue 2 They were recorded within three minutes of each other on the same evening
Clue 3 The spot is about 50 meters from the middle school boundary and about 100 meters from the bus stop
There is no clear answer yet. If you visit Zone B again before the challenge ends and check whether litter has piled up again, you will have one more clue.

Four. What our neighborhood needs

What does each zone need?

Think back to the three zones you saw from above. Litter gathered for different reasons in each zone, so each zone may need something different.

A
Hanjung-ro by the bus stop
What does the bus stop need so people don't drop cigarette butts while they wait?
B
Litter pile in front of the school
What should be at this spot so people don't leave cans and Styrofoam all at once?
C
Road between the school and the apartments
What could we try first, before the habit of littering sets in on this new road?
What does this place need,
and what should it become?
Leave your ideas as a voice note. We will share them in the next issue.

Things you can do

Data plogging
Pick up litter and record its location and type in the app
Go
Voice note
Record what this place needs, in your own voice
Go
One more thing for your next walk
If you find litter piled up in one place, please take a photo before you pick it up. Whether it was in a bag or scattered around is a clue about who left it and how.

Faces in the photo are covered with hearts.

Notes
1. This means it is the first cleanup record for these roads in Itacity.
2. The type drawings are not real buildings. They are simple examples drawn from features we found in each zone's records.
3. On the evening of September 28, 20 cans and 20 pieces of Styrofoam were each recorded in one go, within three minutes.
4. Cans and Styrofoam were rare in the Geochang and Daegu records.
