The construction industry is shifting towards building materials circularity to address waste and resource depletion, driven by environmental concerns, regulations, and new technologies. 

Building materials circularity involves designing, using and reusing materials to minimise waste and carbon emissions. McKinsey and the World Economic Forum highlight the potential of circularity, estimating a revenue opportunity of over $1 trillion in Europe by 2050. 

Companies like Skanska, AECOM, and LafargeHolcim are adopting circular practices, despite challenges such as lack of standardisation and infrastructure. 

The circular economy could save up to $3.7 trillion annually by 2030, the Ellen MacArthur Foundation estimates, underscoring its significance.
