The Zero economy meal tray is a concept product that aims to reduce the amount of plastic waste created by meal service on passenger flights. Each element of the lightweight tray is composed of edible, biodegradable, and/or commercially compostable materials. Made from a range of materials including algae, bamboo, and coffee grounds, the Zero economy meal tray encourages suppliers and airlines to rethink meal service in a more eco-friendly manner. The tray was also designed to raise awareness of the amount of waste generated onboard passenger flights and to encourage consumers to change their behavior.
