jokes apart, it's as if Koreans have a covenant of cleanliness with their environment. the way they consciously avoid littering will leave you in awe. imagine attending a public event like wedding, funeral or political party campaign and no one left a piece of paper of the floor. even in isolated places like mountain hikes or bicycle tracks across bush paths, these guys sincerely love their country.
In the city where I live in South Korea, they use these Automated Vacuum Collection systems to manage waste. They are found in street corners and residential estates. You tap your card to open a metal door and deposit trash.
Once deposited, the waste is transported through underground pipes to a central facility.
The system uses RFID chips to record each household's contribution to ensure proper tracking and billing. Households are charged based on the weight or volume of waste they dispose of.
