주택 건축물의 해체 이후 건설폐기물 현장재활용 시 CO2 발생량에 관한 연구

Recently, various politics for reducing greenhouse gases have been promoted in home and abroad. In domestic construction fields, struggle for reducing greenhouse gas like carbon dioxide is being made a demand in domestic industry as well. In particular, most of greenhouse gases are resulted from using fossil fuels. Construction industry spends a quarter on the volume of fossil fuel consumption. Carbon dioxide is generated by various sources like production, transportation, construction, maintenance, removal stage in life cycle of buildings. Throughout buildings' life, construction wastes generated in construction or removal stage are a factor of CO2 emissions. Therefore, it is expected that reducing and recycling construction wastes generated from construction or removal stage affects reduction of CO2 emissions. In this study, it is calculated CO2 emissions based on wasted concrete volume after dismantling a building in a dwelling. Finally, CO2 emissions are calculated if and only if site recycling construction waste like wasted concrete and producing natural aggregate respectively.
