This is the summary of the technical communication, which exposes some very interesting results regarding the use of single-use tableware in the aviation sector:
Annually, around 7.7 billion passengers travel by plane (ACI, 2017). The menus that are served during the flight, which are quite similar, between the different airlines, are made up of food, packaging and tableware.
To create a more sustainable catering service in flight by applying eco-design measures, it has been performed a LCA. The results have shown that the impacts of reusable and one single use items take place at different stages of their life cycle (79% in the flight phase and 80% in the production phase, respectively).
Variables like material, the weight and the number of reuses influence the gas emissions of greenhouse effect (GHG). The result of this study shows that the lighter single-use items are less harmful under a life cycle perspective. It is recommended to use the LCA methodology for decision-making and legislation development.
