For these tests the waste trolleys were divided into three compartments of equal size: recyclable packaging, non-recyclable and recyclable paper-cardboard.

To facilitate the identification of the different compartments to the crew, the carts were labeled by a color coding, following this order:

  • Recoverable (plastic and glass containers, aluminum wrapping, film, plastic cups, soda cans etc.).

  • Paper-cardboard (newspapers, magazines, printed boarding cards, etc.).

  • Non-recoverable (organic material, wipes, coasters etc.).

The crew responsible for each of the flights where the test was conducted indicated the following observations:

  • Not all compartments should have the same size. Recyclable waste is generated more than not recyclable.

  • The current distribution of compartments should be changed. Some crew members have indicated that the ideal distribution would be to leave the paper-carton in the last place, since during the flight they use more of recyclable and non-recyclable.

  • Instead of the stickers the crew recommend the use of the following colors: yellow for packaging, blue for paper-cardboard and gray for organic.

  • The previous training that the crew receive should be extended, adding the residues that have given rise to doubt during this test phase: diapers, coasters, wipes, etc.

  • It would be advisable to notify passengers by public address before proceeding to the collection of waste, informing them about the sustainable action that is being developed, so passengers can collaborate by delivering the waste separated.
