On the International Day of Zero Waste (March 30), Jaideep Mirchandani, Chairman, Sky One, highlights practices that are reshaping aviation MRO.
The Aircraft Recycling Association forecasts over 12,000 aircraft to be recycled soon
The global aviation industry is striving to achieve net zero carbon emissions by 2050 via diverse strategies and a sharp focus on Sustainable Aviation Fuel (SAF). Meanwhile, some airlines are exploring the possibilities of electric aviation as a low-carbon solution to head towards a greener future. Completely shifting to SAF or a widespread use of electric planes may take more time, and so airlines are now focusing on sustainability beyond operations. In this context, the area that offers feasible sustainable options is Maintenance, Repair and Overhaul (MRO).
Recycling trends
Some of the key practices in the MRO sector, such as the re-utilisation of major parts and components, material recycling, and waste reduction, offer immense scope for reducing the carbon footprint in the aviation sector. For instance, when an aircraft part requires replacement due to wear and tear or damage, the conventional approach involves the airline procuring a new component from an original equipment manufacturer (OEM). However, MRO presents eco-friendly alternatives, such as acquiring a used, serviceable part, to address the issue. High-value components like flight control systems, hydraulic systems, brakes, drums, avionics, and even engines are commonly reused. Recycling aircraft parts not only reduces pollution but also addresses concerns about the environmental impact of manufacturing new components, particularly for costly materials like aluminium, steel, copper, and titanium, making upcycling a responsible choice.
The ‘Aircraft Recycling Global Market Report 2024’ by The Business Research Company predicts growth in the aircraft recycling market. Valued at over USD 4.74 billion in 2023, it’s expected to reach USD 5.14 billion in 2024, with a CAGR of 8.3 percent. The rising number of worn-out airplanes is a key driver. The Aircraft Recycling Association forecasts over 12,000 aircraft to be recycled soon.
Off-wing MRO
Another key trend propelling sustainable practices is the growing acceptance of off-wing MRO. Unlike on-wing maintenance, where the engine is serviced while it remains attached to the aircraft, off-wing maintenance involves removing the engine from the aircraft and transporting it to a repair facility for servicing. The off-wing MRO is helping airlines improve their environmental performance, mainly by reducing the amount of fuel consumed by aircraft during maintenance and the waste likely to be generated.
While promoting reuse in MRO, it is also necessary to keep in mind that used parts cannot guarantee the quality of virgin components. Hence, it is necessary to ensure that each part is carefully inspected, tested, and evaluated for its condition and serviceability. It is also imperative to properly dispose of or recycle parts in keeping with environmental regulations if they are not economically viable.
In conclusion, the aviation MRO sector anticipates greater adoption of waste reduction and recycling practices. Coordinated efforts from stakeholders, including MROs, airlines, and suppliers, aim to intertwine efficiency with sustainability.
