According to previous studies, millions tons of building construction and demolition wastes (CD&Ws) was 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 enormous efforts in the 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 March and December of 2008 in the Construction Air Pollution Control Fee Collection Information System and the Industrial Waste Report System. We audited a total of 4238 projects. In addition, we conducted on-site auditings of 68 construction and demolition projects on the control lost. As a result, suggestions on the two systems to improve the audition and controlling of construction and demolition projects were proposed. 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, 0.062 and 0.3254 ton of CD&Ws were generated per square meters of floor area for the building construction project and the building demolition project, respectively. 3.Assisted 6 companies in preparing necessary documents for applying the Green Building Material label for their recycled products. By the end of the project, three of them filed the applications while the other three filed to do so due to a change on company’s policy or manufacturing process. 4.Amended the working guidelines of 5 construction items so that the CD&Ws could be reused in the public construction projects. Those five items were ‘Concrete material’s, ‘Road subbase aggregate’, ‘Roadbase aggregate’, ‘Asphalt concrete pavement’, and ‘Cement concrete pavement.’ 5.Assisted a selected roadway construction project by using the recycled CD&Ws in its subbase, base, as well as the pavement to serve as a model for other construction projects to used recycled CD&Ws. We assisted the selected project to plan the test of the basic properties of the recycled materials, the examination of the plant for producing the recycled materials, and the on-site construction quality control of using the recycled materials. 6.Studied and developed a 4-year plan for reduction and recycling of CD&Ws in Taiwan. The goal was set to reduce and recycle 30% of CD&Ws in 4 years. An expert meeting and a meeting among all the related government agencies has been held to discuss the plan. 7.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. 8.Assisted the EPA in reviewing 12 proposals solicited from local counties for recycling the CD&Ws generated from household renovation. In addition, a meeting was held for the 12 local counties to report their progress on the project and to share their experiences. 9.Held 1 review meeting of 70 participants for exchanging and sharing the experience in recycling CD&Ws. In addition, 4 workshops were held in different parts of Taiwan to promote the construction recycled products with a total participants of 402. We expected with the implementation of all the above works, the market initiatives and demands for recycled CD&W products would be increased. Thus, the recycling and reuse of CD&Ws could be facilitated and wastes reduced.
