Scenarios analysis shows that a slowing down in the building stock expansion will likely occur in China in no more than ten years. This may open up a transition with profound industrial and resource implications. Increasing businesses for the construction industry may emerge from maintenance, retrofitting, and end-of-life management of existing buildings. The steel industry shall reform its capacity to conform to the growingly available secondary resources and the declining requirement for construction steel. Efficient and appropriate recycling of steel content from waste concrete will play an important role in material conservation. A collaboration of improvements in process material efficiency with lifetime extension and application of high-strength steel may save nearly 40% of primary iron ores for building use in the coming four decades.
