Circular Economy in Transport: Rethinking Assets, Operations & Value Chains

The transport sector is entering a new phase of transformation driven by regulatory pressure, resource scarcity, and the need to reduce environmental impact. While decarbonization remains a priority, the circular economy is emerging as a key complementary strategy, helping stakeholders preserve value, optimize resource use, and rethink linear models.

Beyond waste management, it introduces a life-cycle approach, where up to 80% of environmental impact is determined at the design stage. This shift requires a deep transformation of assets, operations, and value chains across the transport ecosystem.

Our experts’ analysis explores how circular economy principles can be implemented across the transport sector, with a focus on:

• Geographical scope: France and Europe
• Sector scope: rail, road, and aviation
• Asset scope: rolling stock, infrastructure, and buildings
• Value chain scope: design, operations, and end-of-life

The analysis highlights how circularity can create value for key stakeholders, including manufacturers, operators, infrastructure managers, recyclers, and public authorities.

Circular economy in transport is not just about end-of-life—it is about preserving value across the entire lifecycle.

It relies on three key principles:

• Designing out waste from the start
• Extending asset lifespan through maintenance and reuse
• Closing material loops via recycling and recovery

This approach requires aligning decisions across upstream, operations, and downstream phases.

Circular economy relies on strong coordination between:

• Manufacturers and equipment suppliers 
• Transport operators and maintenance providers 
• Recycling and recovery players 
• Public authorities and regulators 

This interconnected ecosystem is essential for efficient material flows and value creation.

Circular economy enables transport stakeholders to:

• Reduce reliance on virgin materials 
• Extend asset lifetimes 
• Develop new value pools through reuse and refurbishment 
• Structure efficient recovery ecosystems 

The objective is clear: reduce, optimize, and close loops across the entire value chain.

Sia supports clients end-to-end, from strategy to implementation:

• Set circular economy objectives
• Anticipating regulatory constraints 
• Auditing inbound and outbound flows
• Optimizing the circular supply chain
• Define recycling processes

We also leverage agent-based AI solutions to accelerate circular transformation, from eco-design to supply chain optimization.

Circular economy is becoming a key driver of performance and resilience in transport.

The challenge is no longer to experiment—but to scale circular models and embed them at the core of operations and investment strategies.
