A Week of Circularity: Circular Aviation

As the first circularity-focused project on the aviation and aerospace sectors comes to a close this month, we are one step closer to witnessing the first fully circular flight take off by 2050 if not sooner. Three and half years since its launch, the EU Horizon 2020 funded project SUSTAINair - coordinated by the AIT Austrian Institute of Technology - is set to bring evidence of the increased sustainability of the airframe value chain: from materials, to circular aircraft design, and end-of-life solutions.

With close to 90% of an aircraft's weight available in the aftermarket for used serviceable materials, leasing companies, owning over half the global commercial fleet, have an opportunity to influence and drive the economic case for aircraft circularity.

🔍 The Science of Impact

Circular aviation is responding to the societal demand for sustainable aviation. Green solutions connected to propulsion are the most talked about aspect of it. Another aspect encompasses circular economy approaches tackling resource consumption and emissions along the entire value chain, including aircraft manufacturing, predictive maintenance, and end-of-life solutions.

SUSTAINair is introducing the circular economy along the entire aircraft value chain.

This includes:

  • Circular design of individual components and joining technologies for airframe construction
  • Real-time structural health monitoring of materials and joints during operations
  • Improved maintenance and repair technologies to extend aircraft life-time
  • Rivet removal demonstrator using robotics & water jet cutting for improved recovery of high-quality aluminum recycling materials

The expected impact of project SUSTAINair translates in cost savings across the airframe value chain: from lower fuel consumption to a marked decrease in take-off gross weight.

🎯 Circularity Roadmaps Explained

The aviation industry is increasingly focusing on circular economy principles to reduce environmental impact beyond waste. A significant portion of the industry already prioritizes recovering functional parts from retired planes and responsibly repurposing or recycling other components. As technology improves these processes, circular economy principles is becoming even more crucial throughout the value chain, from design to decommissioning.

In their recent 2030 Aviation Series, the team at KPMG explains how retired aircrafts, even after over 20 years of service, hold substantial value due to intensified regulations and innovations that unlock value during recycling and disposal. Such is the case for landing gears, auxiliary power units, electrical and flight controls, navigation systems, and cabin seating as nearly 80% of aircraft components and over 90% of an aircraft's weight join the aftermarket for used serviceable materials (USM).

The market for USM is experiencing strong growth, driven by competitive pricing, efficient servicing of aging fleets, sustainability and decarbonization focus, and the increased focus on supply chain resilience. Companies across the aviation spectrum, including airlines, maintenance organizations, and aircraft operators, often resort to USM to save money, as certified USM parts are typically 20-40% cheaper than new parts.

Technologies like augmented reality, virtual reality, and RFID tags are being deployed to simulate the disassembly process, and improve teardown efficiency. Data analytics helps then predict which components will yield the most value and capture key performance indicators. Robotic systems increase speed and accuracy while reducing labor costs.

OEMs like Boeing and Airbus are adopting circular design principles, working towards creating a closed materials loop where retired aircrafts contribute to new ones. On the other end, leasing companies, owning over half the global commercial fleet, have an opportunity to influence and drive the economic case for aircraft circularity.

💰 Investing in the Circular Economy

A year ago, the team at Ark Invest Limited , led by Wall Street pioneer Catherine Wood , launched the first circular economy ETF to score Article 9 status under the EU SFDR: the Rize Circular Economy Enablers UCITS ETF (CYCL).

CYCL provides investors with exposure to companies that are driving the circular economy forward by developing new business models, technologies and systems that enable the transition to a more sustainable, resource-efficient and regenerative economy. Although CYCL has invested so far only across 30 stocks, 70%+ in US market based, its stock selection is quite unique as it follows a thematic classification to score companies on their contribution to advancing the circular economy while also maintaining financial strength.

Specifically, CYCL invests in companies that score high in the thematic classification built in partnership with the team at Sustainable Market Strategies , a Montreal, Canada-based ESG intelligence firm.

Th SMS classification is an enabling taxonomy designed for the investment and research communities with the aim of identifying companies that are making a substantial contribution to “The Transition to a Circular Economy” objective of the EU Taxonomy.         

Each company is assessed for its relative contribution in supporting other companies to enhance circularity within their own business models. SMS Circular Economy Enablers are assigned a score which reflects both the contribution of revenues to circularity as well as their financial strength.

Note: Waste Management, Waste-to-Energy, and First Generation Biofuels are not considered activities that contribute directly as circularity enablers. They are therefore excluded from the circular economy revenue score.  

Here's a simplified summary of the SMS and Ark teams' observations:

  • Waste Management: Collecting and disposing of waste in landfills is a best practice in a linear economy but doesn't contribute to a circular economy.
  • Waste-to-Energy: While generating energy from waste reduces landfilling, it may discourage waste prevention and recycling if consumers believe all waste can be used for energy production.
  • First Generation Biofuels: Biofuels made from food or feed crops, like corn-based bioethanol, are not considered sustainable.

Building the categorization a product value chain perspective does also guarantee a greater degree of alignment with the EU Taxonomy. No wonder ARK’s thematic ETF has achieved Article 9 status under SFDR.
