Singapore Airlines Reveals Major Boost in In-Flight Recycling After New Catering Data

Singapore Airlines Ltd. recently announced a significant increase in its in-flight waste recycling rate for the 2023/24 financial year. Initially, the airline reported recycling only 1.7% of its waste. However, after further investigation and receiving updated data from its local catering company, they revised this figure to an impressive 11%, which translates to 393 metric tons.

The correction came after Bloomberg News inquired about the airline’s recycling practices. Upon closer examination, Singapore Airlines discovered it had severely understated the amount of glass waste recycled—368.1 metric tons instead of the previously reported 29.6 metric tons. This adjustment brought the total recycling figure for the fiscal year up significantly.

Recycling and broader environmental initiatives have become increasingly crucial for airlines and their investors. As the aviation industry strives to achieve net zero emissions by 2050, the focus has turned to sustainable practices, including the use of cleaner fuels and more environmentally friendly aircraft. While measures like reducing single-use plastics and lightening planes by removing heavy items are essential, the most significant progress will come from adopting sustainable aviation fuel and greener jets.

Interestingly, Singapore Airlines also revised its recycling figures for previous years. For the 2019/20 fiscal year, the recycling volume was adjusted to 670 metric tons from 388 metric tons once glass waste data was included. Despite these improvements, the airline’s recycling rate still trails behind some of its competitors. United Airlines reported a recycling rate of about 16% in 2023, Korean Air Lines achieved around 68%, and Qantas Airways reported approximately 23%.

Singapore Airlines has faced criticism for its sustainability efforts before. A trial of paper boxes for economy-class meals on medium- and long-haul flights was not widely adopted after negative feedback on social media for appearing too cost-cutting. However, the airline continues to use paper boxes and bamboo cutlery for short-haul economy flights.

Recycling efforts and sustainable practices remain a significant focus for the airline as it works to enhance its environmental impact and meet industry goals.
