  • 현행 "건설폐기물의 재활용 촉진에 관한 법률" 시행규칙에서는 가연성 건설폐기물의 재활용에 대한 명확한 규정 없이 배출규정만을 제안하여 대부분의 가연성폐기물이 단순 소각 또는 혼합폐기물의 형태로 소각 또는 매립되고 있는 실정이다. 따라서 가연성 건설폐기물의 단순 소각을 최대한 억제하여 연료화 등으로 재활용 할 수 있는 제도적 방안의 마련이 필요한다. 본 연구에서는 이를 위하여 가연성 건설폐기물의 발생 및 처리현황을 분석 조사하였고 국내 폐기물 고형연료관련 제도 및 법규를 검토하였다. 그리고 이를 토대로 국내 가연성 건설폐기물의 연료화를 위한 문제점을 분석하여 가연성 건설폐기물을 활용한 고형연료의 정착을 위한 정책적 방안을 제시하였다.

  • The purpose of this study is to establish a novel system for on-site management of construction and demolition waste. Construction waste has always been one of largest waste in the world and has long lacked an effective management system. Although various countries have planned the disposal of waste at the political level, the real-time and effective management of construction sites has not been mentioned. Especially in China, the continuous development of the construction industry also generates a large amount of waste, and China is not prepared for a large amount of construction waste. In order to alleviate the huge impact of construction waste on society and the environment, this study proposes a waste management method that combines Building Information Modeling technology and Radio Frequency Identification technology. Through this research, by using information technology to manage the generation and discharge of construction waste, and record the amount and information of waste generation, also improve the management method of construction waste.

  • It is needed to classify the kinds of construction and demolition(c&d) debris to 6 catagories of waste concrete, waste asphalt concrete, waste wood, scraps, combustible waste and incombustible waste in order to properly do a separate discharge and to estimate unit generation rate in construction site. Also, in this case, the unit treating cost for mixed wastes should be applied with the unit treating cost for combustible waste. The construction standard materials estimation data is used for basic data for estimating unit generation rate. The mixed wastes in this data should be classified to waste wood, combustible waste and incombustible waste, and their ratio is obtained by using the unit generation rate of Asia Pacific Environment and Management Institute and Seoul Metropolitan Development Institute. The waste amounts generated from newly-built construction can be obtained from multiplying the loss rate by the amount of materials used from construction standard estimation data. Also, those from dismantling construction can be obtained by subtracting waste amount generated during newly-built construction from total input amount of materials in newly-built construction. Those in two cases can be used in construction site. It can be used for estimating the amount generated and establishing the treating plan in the case of setting up the policy of waste management and doing the environment impact assessment.

  • Construction management has been suffering from many problems, which need to be solved or better understood. Most of construction projects have not achieved efficiency as expected. In this context, waste was also considered as a problem of efficiency decrease, and poor production planning was considered as a cause for waste. This study was conducted on the basis of waste concepts and production planning processes based on the philosophies of Lean Construction. A survey to find out the relationship between them was carried out through questionnaire, which was answered by experienced people in construction projects. The results have shown that frequency of wastes occurrence is quite high, and production planning processes are superficially performed in construction phase. There is a significant negative relationship between production planning and waste occurrence (r = -0.262). Weekly Work Plan (WWP) is the most dominant plan for waste control with seventeen in total of nineteen waste factors, and phase plan is the most dominant plan for two remaining waste factors. A case study was adopted to validate the relationship between production planning and waste occurrence. The results showed that the better the project was planned, the fewer the waste would occur on construction sites.

  • It is considered that the construction industry is one of the pivotal players in the national economy in terms of Gross Domestic Production (GDP) and employment. Behind the positive role of this industrial sector to the national economy, the construction industry generates approximately 50 % of the total waste generation from all the industrial sectors. There are several measures to mitigate the adverse impacts of the construction waste such as reduce, reuse and recycle. Recycling would be one of the effective strategies for waste minimisation, which would be able to reduce the demand upon new resources as well as enhance reusing the construction materials on sites. The automated construction waste classification system would make it possible not only to reduce the amount of labour input but also mitigate the possibility of errors during the manual classification process. In this study, we proposed an automated waste segmentation and classification system for recycling the construction and demolition waste in the real construction site context. Since the practical application to the real-world construction sites was one of the significant factors to develop the system, a YOLACT (You Only Look At CoefficienTs) algorithm was chosen to conduct the study. In this study, it is expected that the proposed system would make it possible to enhance the productivity as well as the cost efficiency by reducing the manpower for the construction and demolition waste management at the construction site.

  • 건설폐기물의 발생은 해체단계와 신축단계로 구분할 수 있으며 대부분의 폐기물은 해체단계에서 발생하고 있다. 그러나 최근 국내 신축 건설공사가 연간 150조 규모로 확대됨에 따라 신축공사가 급격하게 증가하고 있다. 특히 건설폐기물 배출이 많은 건축공사의 규모가 100조를 초과함에 따라 신축현장에서의 건설폐기물 발생량에 대한 관리가 요구되고 있다. 신축현장은 해체공사 현장과 달리 발생된 폐기물을 성상별로 분리하여 배출이 가능하며, 상대적으로 이물질 함량이 적게 발생한다. 본 연구에서는 신축현장의 건설폐기물 성상별 발생량을 조사하고, 이를 바탕으로 건설폐기물 발생 원단위를 산정하고자 하였다. 또한 기존 발생 원단위가 콘크리트와 혼합폐기물 중심으로 되어 있어 합성수지, 폐목재, 폐보드류를 추가적인 항목으로 설정하여 원단위 설정을 하였다. 원단위 조사는 총 공사 기간별 발생하는 성상별 폐기물 조사를 실시하였다. 조사결과 신축건설현장은 초반 30%까지와 70% 이후의 공정에서 대부분의 폐기물이 배출되는 것으로 보사되었으며, 혼합건설폐기물의 비율이 45%로 높게 나타났다. 원단위 분석결과 본 연구에서 산출한 결과는 기존의 표준 품셈에 비하여 약 1.9배의 폐기물이 배출되는 것으로 나타났다.

  • 국내 폐기물 발생현황을 살펴보면 건설폐기물의 발생량이 44.6%로서 가장 많은 비중을 차지하고 있으며, 변화하는 사회 환경에 맞추어 건설공사의 규모도 점차 대형화되어 건설폐기물의 발생량은 꾸준희 증가하고 있는 실정이다. 지금까지 건설폐기물 처리 및 재활용 비용이 전체 공사비의 0.5%에서 1%정도 차지하고 있지만, 각 건설현장에서 건설 폐기물을 효율적으로 관리하지 못한다면 전체공사비에서 건설폐기물 처리 및 재활용 비용이 차지하는 비율은 더욱 높아질 것이라고 예상되고 있다. 이는 건설폐기물로 인한 환경적 폐해와 경제적 손실이 심각하다는 것을 암시한다. 위와 같이 환경적, 경제적인 문제를 안고 있는 건설폐기물의 저감 및 재활용의 활성화를 위해서는 폐기물 발생부터 처리까지 포괄적으로 관리해야 할 필요성이 있다. 본 연구에서는 정보교환시스템과 폐기물전자인계서 제도가 각 건설현장마다 활성화 되어 폐기물관리가 효율적으로 이루어지기 위한 방안으로 이미 RFID기술이 적용된 사례분석을 통하여 무선 주파수 인식 기술(RFID)이 효율적으로 적용될 수 있는 방안을 제안 하는 것을 목적으로 한다.

  • Research on construction waste unit was in progress in the 1995 when 'Proper Disposal and Recycling Measures for Construction Waste' was made by the Seoul Development Institute. Such an effort has been made in order to cope with the lack of natural resources in Korea and to utilize the reusable resources. Furthermore, these efforts have also increased due to the improved standing of Korea in the international community. A large number of residential buildings were built in the response to the government's policy by increasing the supply of houses between the 1970's and 1980's. In 2000, more reconstruction and redevelopment was done because of the aged buildings and change of use for those buildings. And the project has been actively promoted until now, which caused a sharp increase in the generation volume of construction waste. In Korea, 8 kinds of construction waste unit, including the standard construction manpower and materials estimation, are introduced. Currently, they provide standards to different building categories and waste properties while for construction sites different standards are applied. This study aims to measure the actual amount of construction waste after sample buildings are dismantled and analyzes the estimation of the waste quantity by using various standard units. Through comparison, this study will figure out the differences among the standard units in order to find out how to apply the standard units properly. Moreover, this research will provide practical measures to apply such units to construction sites.
