Airbus has introduced a new cabin recycling trolley designed to help airlines manage and sort in-flight waste more effectively.
Called the Retrolley, the unit enables cabin crew to separate trash directly on board. It includes a dedicated container for liquids, compartments for stacked cups, separate sections for recyclable paper and plastic, and a bin for non-recyclable items. The layout is intended to make sorting quick and intuitive during service.
The Retrolley’s concept originated with a team of Brazilian aviation students from São Paulo University who were finalists in Airbus’ Fly Your Ideas competition. Airbus refined the original idea in collaboration with Italian manufacturer Iacobucci HF Aerospace to develop a production-ready solution.
After development, Airbus carried out in-flight tests later in the year and presented the finished trolley at the Aircraft Interiors Expo in Hamburg. The design focuses on adaptability so it can be configured to meet different airlines’ service flows and waste-handling policies.
Industry data highlights the scale of the challenge: IATA estimated approximately 5.2 million tonnes of cabin waste in 2016, and projects that volume could double by 2030 if current trends continue. Currently, much onboard waste is collected without separation and handed over to airports, which often send it to landfills or incinerators.
Lucio Iacobucci, CEO of Iacobucci HF Aerospace, emphasized the Retrolley’s flexibility: “As a very simple system, the Retrolley can be used on different flights. Each airline has its own approach and needs, and this trolley is adaptable to various requirements.”
By enabling source separation during flights, the Retrolley aims to reduce contamination of recyclable streams and improve the proportion of waste that can be recycled after landing. Its compartments and liquid-safe container are intended to address common obstacles to in-flight recycling, such as mixed materials and spill risks.
Because the trolley is configurable, airlines can tailor its internal layout and labeling to match service routines, catering setups and local recycling standards. This adaptability helps integrate the trolley into existing galley workflows without major operational changes.
The development also demonstrates a broader trend in aviation toward reducing environmental impacts through practical cabin solutions. Alongside lightweight materials, fuel-efficiency measures and alternative fuels, improving waste handling aboard aircraft contributes to overall sustainability objectives.
Adoption of in-flight sorting systems like the Retrolley will depend on factors such as airline priorities, regulatory frameworks at destination and transit airports, and the availability of downstream recycling facilities. When paired with clear crew procedures and airport collaboration, however, onboard separation can increase recycling rates and reduce reliance on landfill or incineration.
Airlines evaluating the Retrolley can consider how its modular design aligns with their service patterns and waste-management contracts. For many carriers, a simple, adaptable trolley that supports liquid containment and distinct recyclable compartments could be a practical step toward cutting cabin waste sent to disposal facilities.
