Key takeaways

Conventional virgin materials like steel, concrete, and ballast contribute significantly to the carbon footprint due to energy-intensive manufacturing processes.

Recycled materials such as aggregates, crushed glass, and plastics offer sustainable alternatives for transport infrastructure projects.

Collaboration with railway organizations can help minimize risks and promote sustainable procurement in the construction and maintenance of infrastructure.
