A reusable food delivery container scheme running on RFID-tagged stainless steel boxes began operating in Cheonan, South Chungcheong Province, on 28 August 2026. It is the first time the “Returnit” service has run anywhere in the Chungcheong region, and the first time, according to its operator, that AI vision inspection has been applied to reusable delivery container washing anywhere in South Korea.
Returnit is run by Itgreen, a Seoul-based reusable container circulation company founded in November 2020 by chief executive Kim Sun. The service works through the delivery apps rather than alongside them: a customer picks the reusable container option when ordering in Baedal Minjok, better known as Baemin, South Korea’s dominant food delivery app, operated by Woowa Brothers and majority owned by Delivery Hero. When the meal is finished, the customer requests a collection by scanning a QR code and leaves the container outside the door. Itgreen collects it, washes it, inspects it and puts it back into circulation with participating restaurants.
The tag is what makes the loop auditable
Every container in the Cheonan scheme carries an RFID tag. According to VentureSquare, which reported the launch on 28 August 2026, the tag records when the container was supplied to a restaurant, when it was collected from a customer and when it was cleaned, along with how many times that individual container has been used. Itgreen uses the resulting data for two operational purposes: identifying containers that have gone missing or have not been returned, and deciding when a container has reached the end of its working life and needs replacing.
That second use is the quietly important one. A reusable packaging scheme only beats single use if each item completes enough cycles to pay back the material and energy that went into making it, and stainless steel starts that race a long way behind a thin plastic tray. Most reuse schemes cannot tell you where they are in that payback, because they count containers in aggregate: how many went out, how many came back, roughly how many are still in the system somewhere. Per-item cycle counting is a different class of evidence. When the tag holds the wash count for each individual container, the operator can state an average cycle count with a real distribution behind it rather than a modelled assumption, and can see which containers are the outliers dragging that average down.
The same identity data does the unglamorous work of loss control. Returnit’s existing operation, described in a January 2023 interview with Korea Logistics News, pushes real-time container location to delivery riders and sends reminders to customers who have been holding a container too long, with the company claiming a recovery rate approaching 100 per cent. Neither of those functions works on anonymous stock. You need to know which container is sitting at which address, and only a serialised identifier gives you that. This is straightforward asset tracking, applied to an asset worth a few pounds that travels through strangers’ kitchens.
What has not been disclosed
No source in the Cheonan coverage states the operating frequency of the tags or their form factor, and this article will not guess. It is worth setting out why the choice is constrained, though, because the physics here is genuinely awkward. The containers are stainless steel, and metal detunes and shields antennas designed for use in free air, so any tag has to be either specified for on-metal mounting or positioned on a non-metallic part of the assembly such as a lid seal or a moulded recess. The containers also go through repeated industrial washing at high temperature with detergents and disinfectants, which is closer to a commercial laundry or a returnable transit item application than to a retail label. Laundry-grade tags exist precisely for that duty cycle, in both high frequency and UHF variants, and both are used commercially for reusable packaging pools. Which one Itgreen has chosen has not been reported.
AI vision picks up what the eye misses
The other new element in Cheonan is the washing centre itself. The Cheonan Smart Washing Center runs an AI vision automated inspection system that photographs containers after cleaning and analyses the images for residual foreign matter and for signs of damage. Itgreen describes this as the first automated application of AI vision to reusable delivery container washing in South Korea. “We plan to resolve cleaning quality issues difficult to see with the naked eye by introducing AI vision,” Kim Sun told VentureSquare.
The inspection sits inside a seven-stage wash and disinfection process, and Itgreen’s own material claims each stainless steel container displaces more than 300 disposables over its life. Pair that claim with the per-container RFID cycle count and you have something unusual in reuse: a marketing number that the operator’s own data can either substantiate or contradict.
A 2024 commitment, delivered
The Cheonan centre is not a standalone launch. Woowa Brothers signed agreements with Cheonan City and Gwangmyeong City on 25 November 2024 under a smart city programme run by MOLIT, South Korea’s Ministry of Land, Infrastructure and Transport. The package covered an AI-inspection washing centre in Cheonan, described at the time as the first automated facility of its kind in Chungcheong, plus roughly 20 battery swapping stations for electric two-wheelers in Cheonan and 10 in Gwangmyeong. The agreements were signed by Cheonan Mayor Park Sang-don and Woowa Brothers vice president Ham Yun-sik. The August 2026 opening delivers that commitment, around 21 months later.
Woowa Brothers marked the launch with a promotion of 10,000 won off orders over 15,000 won, running until 3 September 2026. Kim Joong-hyun, sustainability management director at Woowa Brothers, framed Cheonan as the starting point for extending the reusable container service across the wider Chungcheong region.
The number that complicates the story
The case for all of this is not hard to make. South Korean delivery meals generate an average of 18.3 plastic containers and 147.7g of plastic per meal, working out at 1,342 containers and 10.8kg per person per year, and only 45.5 per cent of plastic delivery containers are recyclable. Reusable container orders have grown fast: up 461.6 per cent in 2023, up 140.2 per cent in 2024, and up 23.2 per cent in 2025.
But a report published by SocialValue on 31 August 2026 sets a much less comfortable figure alongside that growth. In Seoul, cumulative restaurant sign-ups to reusable container schemes rose from 2,026 in 2024 to 2,775 in 2025 and 3,014 by August 2026. The number of restaurants actively maintaining the service went the other way: 890 in 2024, 849 in 2025, and 797 in August 2026. More restaurants have tried it every year, and fewer are still doing it.
Rising orders alongside falling active participation is a churn problem at the restaurant end of the loop, not a demand problem at the consumer end, and it is the constraint that decides whether the Cheonan model travels across Chungcheong or stalls. RFID will not fix restaurant churn on its own. But a system that holds the supply, collection, wash and cycle history of every individual container is at least positioned to show where in the loop containers are getting stuck, and for a sector whose sustainability claims usually rest on modelling rather than measurement, that is not a small difference.
