To reduce both carbon dioxide (CO2) emissions and costs, Japan’s ‘largest’ airline All Nippon Airways (ANA) will replace its traditional dry ice method of in-flight food and beverage refrigeration with a product made from materials used as food additives.
Adoption of the new cooling technology is expected to help reduce CO2 emission levels by around 1,700 tonnes per year, in addition to saving the company yearly packaging costs of approximately ¥200m (£1,320).
The new refrigerant will be used in the in-flight carts for maintaining a stable temperature of food and drinks for long periods of time. In addition to the sustainable cooling, staff safety will be improved due to a lower risk of frostbite compared with the handling of dry ice.
