الوصف: Key points • The housing industry is an institution with recognisable 'rules of the game' that shape industry structure and actor interactions, which in turn will shape responses to the development of a circular economy (CE) strategy. • Understanding the structure of building-material supply chains is essential for policy development seeking to reduce carbon intensity of new material choice and use in the housing industry. • Housing industry engagement with the CE and reducing greenhouse gas (GHG) emissions by relying less on virgin materials and increasing reuse, recycling and resource recovery will require development of efficient and responsive 'used' materials markets. Key findings There has been limited consideration and engagement with circular economy (CE) principles within the residential housing industry and its material supply chains. A starting point for informing the development of a CE is to analyse the institutional arrangements of material supply chains that supply manufactured building materials containing embodied GHG emissions to the residential housing industry. This type of analysis can assist in showing how the housing industry and its supply chains can contribute to reducing GHG emissions by using low-carbon materials and relying less on virgin materials. It can also assist by showing how the industry can close loops by reducing waste through reusing, recycling and recovering resources in the industry and its supply chain. The material flow analysis (MFA) found that data for tracking material stocks and flows throughout the residential construction sector is inadequate. This applies to new and existing materials as they move into the construction and demolition waste stream. A novel approach was developed, using top-down available datasets and bottom-up generation of data. It showed that the use of concrete continues to increase, which is increasing the carbon intensity of housing. Further, while the number of houses constructed each year has not changed significantly over the past 50 ...
