For this second test of waste separation on-board in 8 European Union flights, “Waste Trolleys” were used with a bucket divided into three compartments of different sizes, with the space being distributed as follows: 50% recyclable, 25% paper, 25% non-recyclable. These compartments were labeled following the color signs commonly used at national level: recyclable – mostly light packaging – = yellow, paper = blue, non-recyclable = gray.
Once the waste was arrived at Gate Gourmet facilities, the following aspects were assessed:
Quantity and quality of the separated waste
In business class, the following amount of waste has been collected:
Recyclable: between 0.66 and 2.00 kg.
Paper and cardboard: between 0.42 and 2.18 kg
Non-recyclable: between 0.62 and 1.54.
In economy class, the following amount of waste has been collected:
Recyclable: between 1.60 and 6.38 kg
Paper and cardboard: between 0.66 and 1.46 kg.
Non-recyclable: between 0.82 and 1.16 kg.
Regarding the quality of the separation, in general the crew has correctly separated the waste. Some residues incorrectly deposited have been observed:
Paper cups deposited in the Recyclables compartment, instead of Paper.
Cans, plastic cup and glass bottle deposited in Non-recyclable, instead of Recyclable.
Coffee / infusion bag, bread and mixed waste in a bag deposited in Recyclables, instead of Non-recyclable.
Comments of the crew
These have been the main comments received by the crew in relation to the ease of separation of waste with the new prototype:
It would be advisable to put a sticker on the lid of the opening of the trolley with the list of waste that goes in each compartment.
The trolley has a drawback of design, and to access all compartments you have to remove the trolley completely from the galley.
The tweezers used for the bags are not operational as they are not easy to put on and take off.
Many passengers, with the aim of collaborating, give their waste together, inside the coffee cup or all together in a closed plastic bag, which does not allow separation.
Doubts have arisen with some waste: plastic seals, paper bags, paper tablecloths, puzzles, drink removers.
