Gwangjin District Promotes “Trash Diet” for All Residents, Cutting 30g a Day

Checklist Produced and Distributed
Encouraging Practical Waste Reduction in Everyday Life

Gwangjin District in Seoul (District Mayor Kim Kyungho) is launching a full-scale effort to spread the resident-led practical campaign for reducing household waste, titled the “1·1·30 Sseuda (Trash Diet).”

On the 25th, the district announced that it will produce and distribute the “My Daily 30g Trash Diet Checklist” and install experience zones at major facilities, thereby promoting waste reduction in everyday life on multiple fronts.

The “1·1·30 Sseuda” campaign is designed to encourage each resident to reduce their daily waste by 30 grams. If one person participates, it leads to an annual reduction of about 11 kilograms, and if all residents join in, it can reduce household waste by several thousand tons. It is also a preemptive measure to build a sustainable resource-circulation city ahead of this year’s ban on direct landfilling of household waste at the Sudokwon Landfill.

The newly produced checklist includes the weight of each type of waste, methods to reduce items that are difficult to recycle, and guidelines for proper waste separation and disposal. It intuitively shows the weight of everyday waste such as delivery containers, disposable cups, wet wipes, and plastic bags, so that residents can review their own disposal habits. By checking off action items such as using tumblers, avoiding excessively packaged products, and not leaving food waste, residents can participate easily and with interest.

The district will also operate “weigh your trash” experience zones and promotional booths for waste separation and disposal at major facilities such as the Gwangjin Future Technology Experience Center and each neighborhood community center. It will simultaneously provide customized support for waste separation that reflects different living conditions, including single-person households, international students, and apartment complexes, and plans to increase the reduction effect by linking these efforts with policies to expand the use of reusable containers.

Since 2020, Gwangjin District has implemented various waste-reduction policies, such as promoting recycling and strengthening publicity on proper waste separation and disposal. As a result, it achieved a 9.5% reduction in household waste, cutting about 3,491 tons by last year.

Gwangjin District Mayor Kim Kyungho said, “Cutting 30 grams a day may seem like a small action, but if all Gwangjin residents take part, it can create a big change,” adding, “We will continue to expand various publicity and experience programs so that people can participate easily and enjoyably.”
