| Abstract |
As the amount of CO2emission in Korea is ranked 9th and the increasing rate of CO2emissionis highest in the world, it isstrongly necessary to devise methods to decrease the amount of CO2in each industry as the basis of establishingenvironmentally sustainable production system. This paper aims to identify the characteristics of CO2emissions fromconstruction wastes throughout the simplified LCA (Life Cycle Assessment) and suggest the strategic guideline for theconstruction waste management plan to decrease CO2. As a result of LCA on the case of a high-rise residential building project,total sum of CO2emission generated from construction wastes appeared as 6,818,123kg-CO2and CO2emission per unit floorarea as 21.01kg-CO2/ß≥. The principal waste materials generating more than 95% of CO2are materials such as reinforcing bar,temporary materials, cement, ready-mixed-concrete, concrete products, and tile, which have relatively high unit emission rate ofCO2in the process of production. Besides, more than 92% of CO2was generated from the activities such as structure work,plaster work, temporary work, and tile and stone work, which are generally executed in the early phase of the wholeconstruction period. Reflecting these results, the guideline for the construction waste management plan was recommended. Ifthe waste management plan is established considering the guideline suggested, there would be high potential to decrease theamount of CO2generated from construction wastes. |
