Towards an 80% Cabin Recycling Rate at Transavia
A behaviour-centered design intervention to improve waste separation on board
The aviation industry is under increasing pressure to reduce its environmental impact. While much attention has been given to reducing fuel consumption and emissions, improving onboard waste management also offers opportunities to contribute to sustainability goals. Since December 2022, Transavia has separated waste on board its aircraft and aims to reduce residual waste by 80% by 2030 compared to 2022 levels, while achieving an onboard recycling rate of 50% by 2026.
Despite these ambitions, a substantial amount of recyclable material still ends up in the residual waste stream. Waste analyses showed that onboard waste currently consists of approximately 45% recyclable material and 55% residual waste. However, the residual waste still contains approximately 15% paper, 15% PMD (plastic, metal and drink cartons), and 5% glass, demonstrating considerable potential to improve waste separation.
Previous research has mainly focused on reducing food waste on long-haul flights, whereas the role of passengers in improving onboard waste separation on short-haul flights remains largely unexplored. This graduation project therefore investigated how passenger and cabin crew behaviour can contribute to increasing onboard recycling rates.
To understand the onboard waste management system, observations, interviews, onboard questionnaires, and waste analyses were conducted. The values and needs of the four key stakeholders, passengers, cabin crew, cleaning staff, and Transavia, were identified and analysed using behavioural theories, including the COM-B model, the Fogg Behaviour Model, and the Habit Loop.
The analysis showed that ineffective waste separation is caused by multiple factors. Although passengers are generally willing to contribute, they are largely unaware that waste is separated on board and do not know how they can help. As a result, cups are frequently used as small waste bins, reducing the effectiveness of waste separation by cabin crew due to time pressure, hygiene concerns, and the additional effort required.
Based on these insights, multiple concepts were developed, prototyped, tested, and evaluated. This iterative design process resulted in AERO, a redesign of Transavia's existing waste trolley through a combination of add-ons and internal modifications. AERO increases Awareness of onboard waste separation through improved trolley signage and verbal communication during waste collection. It enhances Engagement in better waste separation by nudging passengers to hand over empty cups, making waste separation easier for cabin crew. Furthermore, AERO improves the onboard Recycling rate by approximately 20 percentage points, from 45% to 65%. Finally, it Optimizes the waste collection process by providing cabin crew with a dedicated tray for stacking cups and an additional paper waste stream.
By building upon the existing waste trolley and operational processes, AERO requires relatively limited investment while improving environmental performance, strengthening Transavia's sustainable brand image, and reducing waste processing costs. The project demonstrates that combining behavioural design with practical system adaptations can improve onboard waste separation and contribute to Transavia's long-term sustainability ambitions.
