Korean Air is upgrading the in-flight meal containers it has used for the past two decades with plant-based alternatives.

Beginning in December, the airline will gradually introduce entrée containers made from non-wood pulp derived from materials such as straw, sugarcane and bamboo. The initiative supports Korean Air’s efforts to reduce plastic use and contribute to global carbon-reduction goals. Following initial rollout on select routes this December, the airline plans to expand the new containers across its entire network by the end of 2026.

The new containers will be used for main entrées offered on board, particularly Korean and Western meals in economy class.

Made from plant-based pulp that does not require cutting down trees, the containers offer an alternative to traditional plastic and paper products. They also provide strong heat resistance and durability, maintaining their shape during extended exposure to high temperatures.

“This transition to new in-flight meal containers is an essential long-term investment in environmental protection and sustainable operations,” an unnamed source from the airline said on a press release. “We remain committed to advancing our sustainability initiatives, aligning with global decarbonisation trends in aviation, and delivering greater value to our customers.”
