The issues like energy saving, carbon reduction, and sustainable development have gradually become essential topics respected by all nations in view of deteriorated global warming and greenhouse gas emissions probably causing climate changes of the Earth. Comparably, the recycling of resources, reducing the demand of exploiting natural raw materials, will contribute to the recycling-oriented society. According to statistics, the Taiwan construction industry accounts for 25% of the total amount of carbon dioxide discharged. Therefore, it has become the responsibility of the industry to implement energy saving and carbon reduction. With the major objective to estimate the building demolition projects in Taiwan, we retrieved data in the National Industrial Waste Declaration System (Environmental Protection Administration) and other data (Construction and Planning Agency) from July 2008 to September 2009 and used the technique of data mining and decision tree to estimate the output of demolition wastes from building demolition projects, which generate a simple rule set for construction wastes effectively controlled by the competent authorities. Because of administrative human resource is insufficient, management affairs of demolition waste are difficult to total control. Based on above reason, this study tried to develop a total E-DemolitionWaste Management System (e-DWMS).The information technology includes Radio Frequency Identification (RFID),Global Positioning System (GPS), Vehicle Detector, Car License plate Identification, Weight in Motion, ASP.NET, SQL,and CCD monitor are used to establish the e-DWMS. e-DWMS contain vehicles management, demolition waste subsystem and website query interface. After a short term validation in field, the e-DWMS own significance influence in efficient and improvement on process of demolition waste. Administrator would get more detail information about demolition waste in truck immediately, and the illegal dispose of demolition waste should be effectively prohibited. The e-DWMS is a remarkable assistant tool in demolition waste management. Implementing good strategy of waste minimisation and management on construction projects will help reduce the significant quantities of demolition waste sent to landfill and make a substantial contribution to sustainable development. The purpose of this strategy is to assist construction clients, design teams and main contractors reduce waste on their construction projects. More efficient use of materials would make a major contribution to reducing the environmental impacts of construction including reducing demand for landfill and the depletion of finite, natural resources. This would also contribute to the economic efficiency of the sector and of the taiwan as a whole.Major improvements in materials efficiency are possible, without increasing cost, by: minimising the overall creation of waste resulting from, for example, overordering or inefficient design; reducing the quantity of material sent to landfill during the construction process through effective waste management; recycling materials already on the construction site into the new construction project; using more recycled materials and mainstream products with higher recycled content. This research is to study the reduction plans as well as the 3R (reduce, reuse and recycle) actions adapted by the advanced countries for reduction of building demolition waste. The objective is to develop action strategies for reduction of the building demolition waste in Taiwan, based on the local market, codes, and regulations. The results of this study to establish a demolition waste knowledge management system to facilitate government agencies and construction industry for use as an education advocacy
