초록
건설 산업은 혼합 폐기물 발생이 많고, 잦은 설계변경으로 인해 전략적인 폐기물 관리가 어려운 것이 현실이다. 이러한 현실 때문에 현장에서는 단순히 발생된 폐기물을 분류하여 보관 및 처리하는 수동적인 사후대처식 폐기물 관리방식을 고수하고 있다. 그러나 사후대처식 폐기물 관리방식은 체계적인 건설폐기물 관리가 어려워 현장의 폐기물 절감 노력을 저해할 뿐만 아니라 폐기물 중간 처리 업체에 의존하는 원인이다. 본 연구에서는 사후대처식 건설폐기물 관리 방식의 한계를 극복하고 보다 체계적으로 건설폐기물 관리를 수행하기 위해 폐기물의 성상, 발생량, 발생 시점을 예측하는 건설폐기물 관리시스템과 건설폐기물의 현장재활용을 유도하는 폐기물 공유 체계를 제안하고, 대상건축물에 적용하여 시스템의 유효성을 검증하고자 한다.
The problems of environmental pollutions and resources depletion have been growing issues in global construction recently. Efforts to reduce $CO_2$ emission have been also made in all sectors of construction industry these days. As one of the biggest industries that consume a huge amount of resources and generate complex construction wastes, the construction industry has significant impacts on environment issues. However, systematic approach to manage wastes has been rarely made, and most construction wastes from construction sites are being land-filled or incinerated. In this study, a system is proposed to predict the amount of wastes in visual formats, and to control the process of wastes management. The system's main functions include : (1) to estimate the amount of wastes to be generated in project schedule, (2) to categorize the types of wastes, (3) to determine the timing of taking out wastes from sites, and (4) to share information regarding wastes for recycling. A huge amount of wastes are generated in construction process, but most of the wastes have been discharged in forms of mixed wastes, which make them hardly reused. The system not only provide information on wastes to be generated, but also prevent mixing various wastes by classifying them by types and schedules. This features of the system, along with functions to share wastes information with other agencies outside the site, are expected to enhance the level of wastes recycling to a great extent. By saving construction materials through wastes recycling, the system also contributes in reducing $CO_2$ emission.
