碩士 === 國立中央大學 === 土木工程研究所 === 90 === Development of a Recycling and Reuse System for Building Demolition Wastes Abstract According to study, there are more than 11,600,000 tons of building demolition wastes generated each year in Taiwan. Since those wastes are neither accepted in most of the regular landfills, nor accepted in the incinerators in Taiwan, many of them is dumped illegally somewhere which develops hazards to the environment. With the higher demand for better living and working facilities, building demolition wastes generated each year in Taiwan are likely to increase in the future. Therefore, the proper treatment of those wastes becomes an issue more and more important for the society. Recycling and reuse of building demolition wastes gradually become a regular practice in those advanced countries such as United States, Japan, Canada, and European countries. More than 50% of recycling rate is reported for those countries. Japan and England even have a recycling rate more than 80%. Most of them are reused for roadway base and backfill, or for land backfill. Some of them are used for replacement of concrete aggregate to make various kinds of concrete products. With the “sustainable development” becoming a global trend and at the same time the local shortage problem of concrete aggregates, recycling and reuse of building demolition wastes provide sound solutions. This research is to study the recycling and reuse system implemented in the advanced countries. The objective is to develop a local one for the building demolition wastes in Taiwan, based on the local market, codes, and regulations. Literature reviews on the related research are conducted. Local codes, regulations, practice, and related market factors holding back the realization of recycling and reuse of building demolition wastes are investigated. Finally, a recycling and reuse prototype system is developed as a result after reviewing with related government and private agencies. Necessary future revisions of the current practices, codes, and regulations are suggested.
