According to previous studies, millions tons of building construction and demolition wastes (CD&Ws) were generated each year in Taiwan. Nonetheless, most of the contents in CD&Ws, such as metals, concrete debris, brick, woods, plastics, glasses, are recyclable. Following the global trend of sustainable development worldwide, the Taiwan EPA (Environmental Protection Administration) has been putting efforts in recycling and reuse of the CD&Ws in Taiwan. Special attentions have been given to those CD&Ws generated from household renovation. This project was to assist Taiwan EPA in achieving the goals of reducing and recycling of CD&Ws and has completed the following work items： 1.Completed the task of auditing the data between January and November of 2009 in the Construction Air Pollution Control Fee Collection Information System and the Industrial Waste Report System. We audited a total of 3568 projects and produced a list of projects for the EPA. Those projects need further inspection for correct data reporting. 2.Analyzed the data in the EPA’s Industrial Waste Report System to identify the factors affecting the generation of CD&Ws. Factors identified including the functional purpose of the building,the structural type of the building, and whether recycling is implemented on site. In addition, according to the data of the Industrial Waste Report System, 0.053 and 0.314 ton of CD&Ws were generated per square meters of floor area for the building construction project and the building demolition project, respectively. 3.Conducted literature reviews and developed local strategies for Taiwan EPA to facilitate the construction waste management. 4.Submitted six of the previously developed construction specification drafts to the Council of Agriculture, Executive Yuan, as their reference in making their construction specifications. The six items included 「General Concrete」、「Base Aggregate」、「Subbase Aggregate」、「Asphalt Pavement」、「Cement Concrete Pavement」 and 「Curb and Culvert」. 5.Maintained the website of the Green Building Products in the EPA and updated the corresponding information. Completed tasks included changing of the web address, updating the application information of the recycled product Green Mark, adding the listed name of the companies obtained the recycled product Green Mark, and adding a statistical counter for recording the number of people visited the website, and so on. 6.Assisted the EPA in holding two meetings in developing a 「Construction Waste Reduction Plan」in Taiwan. It was estimated that by conducting the three work items in the plan the construction wastes can be reduced by 20% and a recycling rate of 40% could be achieved. 7.Submitted two items, namely the「CNS1240 Concrete Aggregate」及「CNS2466Cement Concrete Aggregate」to The Bureau of Standards, Metrology & Inspection for making the revision of the national standards. 8.Completed the making of a 6-minute video to promote on-site recycling of construction wastes in construction projects. 9.Inspected 11 recycling companies for proper operations and data reporting. 10.Kept track on the progress of the 14 participated counties in the「Renovation Wastes Reduction Plan」. In addition, a workshop was held on 98/6/29~98/6/30 for techniques in renovation waste reduction. 11.Held 1 conference of exchanging and sharing the experience in recycling CD&Ws. There were 44 participants. In addition, 3 workshops were held in different parts of Taiwan to promote the construction recycled products with a total participants of 362. 12.Assisted the EPA to attend and present a paper in the WASCON 2009 International Conference, which was held in Lyon, France on June 2-5, 2009. With the implementation of the above works, the recycling and reuse of CD&Ws can be facilitated and the wastes can be reduced.
