Research on CO2 Emission Reduction of a Steel Structure Prefabricated Building Considering Resource Recovery

This paper constructs a carbon emission calculation model for the production, recovery and transportation of steel structure prefabricated building components. Taking a steel structure sales office in Beijing as the research object, the carbon emissions of the dismantled components under non-recycling and different recycling conditions (transport distance and recycling ratio) were calculated. From the perspective of reducing CO2 emissions, the feasibility of recycling steel components in sales offices is analyzed.
