Household waste fell 2.3 percent and recyclables rose 5.8 percent from February through July compared with a year earlier, with more than 3,600 residents taking part in education programs. Waste bags are opened on-site to provide a sorting report card, and violation notices now list the specific items disposed of incorrectly to guide better habits.
Gangnam-gu's "Healthy Resource Circulation, Wellth" project cut household waste by 1,052 tons and increased recyclables by 905 tons in the six months from February through July compared with the same period last year.
"Wellth" — a play on the Korean phrase for "disposing of waste well" — is Gangnam-gu's resource-circulation campaign. Launched in earnest this year to coincide with the Greater Seoul area's ban on direct landfilling of household waste, the campaign aims to make proper waste sorting feel less like a complicated set of rules and more like a familiar, healthy lifestyle habit.
The results are measurable. Household waste generated in Gangnam-gu from February through July totaled 45,233 tons, down 1,052 tons, or 2.3 percent, from 46,285 tons in the same period last year. Recyclables over the same period rose from 15,599 tons to 16,504 tons — an increase of 905 tons, or 5.8 percent.
The district attributes the improvement to a combination of on-site inspections, resident education programs, and public awareness campaigns, which it says helped spread correct sorting practices.
Education programs were expanded to cover practical, everyday content for participants from children to adults. About 3,600 residents received waste-sorting instruction this year. Weekly hands-on sessions at the newly renovated Gangnam Environmental Resources Center exhibition hall, which reopened in April, drew more than 500 participants, while outreach visits to daycare centers and elementary schools reached more than 1,800.
More than 130 residents joined the "Bi-il-bi-jae Challenge," a community participation program in which residents certify that they have properly sorted waste vinyl in their daily lives. About 1,200 people took part in the "bag-opening campaign," in which standard waste bags are physically opened to check for incorrectly mixed items.
Since March, the district has introduced a "composition analysis" — a sorting report card — at bag-opening sites, giving residents an at-a-glance breakdown of what they disposed of incorrectly.
Each bag is examined like a health checkup and its contents sorted into food waste, waste plastic and vinyl, paper, bottles and cans, and other items such as clothing and glass. Based on the results, the resident's sorting health is rated "Healthy," "Caution," "Alert," or "Obese," and a QR code links directly to guidance on correct disposal methods.
Starting this month, the district also redesigned its violation notices. Rather than simply informing residents that a violation occurred, the new notices specify exactly which items were the problem: food waste, vinyl, plastic, paper, cans and scrap metal, bottles, non-combustible waste, other items, disposal time violations, or disposal location violations. The goal is to let residents immediately understand what they did wrong and correct it the next time they put out their waste.
The district plans to move beyond enforcement-centered management and develop its resource-circulation policy into one where residents can check and correct their own sorting habits. It intends to sustain education, hands-on experiences, on-site inspections, and specific feedback to build what it calls "everyday resource-circulation fitness" among residents.
"Waste sorting is the most fundamental action we can take to reduce household waste and return discarded recyclables to use as resources," Gangnam-gu District Mayor Kim Hyun-ki said. "We will continue a range of resource-circulation policies so that proper waste sorting becomes a settled lifestyle habit for our residents."
