Exhibitions of art can, and perhaps should, be thought-provoking, which is exactly the goal of the temporary showing ‘Get Onboard: Reduce. Reuse. Rethink’ by design studio PriestmanGoode at the Design Museum in London. Unlike typical art, though, this exhibit is a concept design that could change the way we travel, or at least the environmental impact when we do.

With its eyes on a future of eliminating single-use plastic, PriestmanGoode has focused its problem-solving skills toward airline travel. The studio has looked for ways to eliminate the estimated 2.2 pounds of waste created per passenger per flight, a weighty problem that adds up to around 5.7 million tons of cabin waste annually worldwide. PriestmanGoode has taken a multifaceted approach to the problem, beginning with the meal tray and eating accessories on long flights.

The designers have come up with functional and surprisingly attractive plastic alternatives for in-flight eating. Some of the plant-based items are washable and reusable: serving trays that are made out of coffee grounds and husks; dishes made from wheat bran; and sporks made from coconut wood. The cups are a two-part design, with a reusable outer layer made from rice husks and a PLA binder. The disposable interior liner is made from algae.

Other packaging saw sustainable upgrades, too. The main dish is covered in a bamboo lid, an earth-friendly alternative to petroleum-based plastic. For side dishes, the lids are made out of algae or banana leaves, and the dessert lid has a wafer design that distinguishes it from the other lids to easily identify what is underneath. Single-use condiment containers were tossed in favor of capsules made out of soluble seaweed. For easy composting, everything packs into the main meal lid.

PriestmanGoode also presents a refillable water canister designed to fit in a seat-back. It has also worked with airline representatives to design a central water refill station as a comprehensive, sustainable alternative to plastic water bottles.

Although the design elements of the concept meal tray are innovative, an equally important goal of the exhibit is to raise awareness about the impact travel has on our environment, and not just in the food consumed. While there are still many steps the airline industry needs to take to lower its environmental impact, PriestmanGoode wants travelers to consider their own consumption habits by only using long-lasting and reusable products that they need.

The exhibit will show until February 9, 2020.
