Circular economy (CE) approaches highlight the potential of construction materials to achieve circularity and sustainability in resource-efficient construction systems and industries. ImplementingCEat thematerial level involves factors such as efficiency, durability, waste reduction through recirculation, and replacement, while encompassing criteria that define circularity in buildingmaterials.Understanding the inherent characteristics and behaviours of these materials is crucial for maximising their circularity potential.This chapter analyses key properties of traditional construction materials, such as concrete and steel, alongside novel sustainable materials like bamboo, timber, and biomaterials. It identifies and proposes methods to promote circularity at the material level. Additionally, the chapter explores the application of CE principles to both traditional and innovative constructionmaterials. Furthermore, the chapter discusses indicators designed to assess circularity at the material level, serving as valuable tools for informing decision-making and implementation practices in the construction sector. Various types of indicators are presented, categorised as strategic, generic performance, performance, and water consumption indicators. Strategies aligned with waste hierarchy principles are outlined, emphasising the reduction of construction and demolition waste, lowering greenhouse gas emissions, conserving energy, and optimising costs and water resources.

Abstract
Circular economy (CE) approaches highlight the potential of construction materials to achieve circularity and sustainability in resource-efficient construction systems and industries. ImplementingCEat thematerial level involves factors such as efficiency, durability, waste reduction through recirculation, and replacement, while encompassing criteria that define circularity in buildingmaterials.Understanding the inherent characteristics and behaviours of these materials is crucial for maximising their circularity potential.This chapter analyses key properties of traditional construction materials, such as concrete and steel, alongside novel sustainable materials like bamboo, timber, and biomaterials. It identifies and proposes methods to promote circularity at the material level. Additionally, the chapter explores the application of CE principles to both traditional and innovative constructionmaterials. Furthermore, the chapter discusses indicators designed to assess circularity at the material level, serving as valuable tools for informing decision-making and implementation practices in the construction sector. Various types of indicators are presented, categorised as strategic, generic performance, performance, and water consumption indicators. Strategies aligned with waste hierarchy principles are outlined, emphasising the reduction of construction and demolition waste, lowering greenhouse gas emissions, conserving energy, and optimising costs and water resources.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
