Comedian Jang Dong-min, often referred to as the "brain of the broadcasting industry," has developed another eco-friendly technology and secured a patent for it.

Pureun Haneul, an eco-friendly startup where Jang serves as CEO, announced that it has co-developed a "lightweight PET bottle screw neck technology" with Namyang Magic, a company specializing in container production. The "Eco-Ring," which applies this technology, is an eco-friendly solution that reduces plastic usage by optimizing the structure of the bottle neck while maintaining the sealing performance and durability of existing PET bottles.

Jang introduced the technology himself during an appearance on MBC's "Radio Star" this past April. At the time, he explained, "Since it is realistically difficult to completely eliminate plastic, I focused on reducing mass and removing unnecessary elements." It is reported that the Eco-Ring technology is already being applied to containers for products such as Dongwon Tuna Liquid and canola oil, which are currently on the market.

This is not the first time Jang has developed eco-friendly technology. In 2021, he devised a "PET one-touch removable container packaging" technology, which allows the label to be automatically removed the moment the cap is twisted open by changing the label orientation from horizontal to vertical. He filed for a patent for this technology and completed the official registration the following year.
