Recently, it is necessary to establish an eco-friendly construction system through recycling of waste material management at construction sites. This is required to reflect the times that require a carbon reduction system in construction as part of domestic and overseas carbon dioxide reduction. Therefore, we intend to establish eco-friendly construction management as part of resource recycling and carbon reduction through recycling technology for waste fibers generated at construction sites.

According to the statistical data of the Ministry of Environment, 47million tons of construction waste were generated, and 96.7% of them was recycled in 2005. However, the recycled products seem to be remained under low quality. Because mixed demolition and construction waste, so called DC Waste, including concrete, brick, plaster, lumber, plastics building materials, paper and some dirt and stone, is very variable and difficult to estimate its exact composition, it is regarded as having little or no value to the construction industry. 'The Research group on recycling of construction waste' was started by the Housing & Urban Research Institute(KNHC), which is sponsored as a large scale national project by the Ministry of Construction and Transportation. This research group intends to establish recycling system through planing, processing, developing practical technology, and eventually contribute to save natural resource and to vitalize the industry. In this paper an overview of DC waste management and recycling technology is given in some detail. Particularly, "recycling law of construction waste" and recent research trends on recycling of construction waste are discussed.

In Korea, because of the shortage of reclaimed lands and disposal sites and the small size of national land, A political measure for construction wastes recycling is needed. therefore we studied the current state of construction wastes recycling and the act for it. And we analyzed problems and unreasonable regulations regarding the wastes. So we suggested an alternative act to increase the construction wastes recycling.

In order to establish active and effective recycling plans on construction wastes, the study seeks to built unit generation data per construction waste types on each sector, prepare units data on urban construction waste generation and serve as meaningful data on the establishment of policies on construction waste recycling targeting urban regions. The significance of the study is on the establishment of construction waste recycling plan prior to generation, not as complementary measures on construction waste generated.

Concrete produced from the construction wastes has been largely used as the recycled aggregate. These wastes, however, is mostly used as filling materials. For any recycled aggregate like waste concrete to be used as normal construction materials, it is necessary to actively find out the proper market places as much as possible with the improved quality. In this study, we have investigated the present status on the occurrence and treatment of both domestic and abroad construction wastes, and also the recycling status and related legislation with some inhibitory factors. Based on these investigations, we suggested some effective ways to increase the recycling of construction wastes.

Recently, the construction wastes increase rapidly due to the revitalization of reconstruction and redevelopment, the development of new urbanization of large housing development, the expansion of social infrastructure, and so on. To solve rapid increase of construction waste, the government established "the rule on the promotion of recycling of construction waste" in December, 2003. According to the rule, construction wastes can be recycled by either processing on commission or discharger of construction waste. This study proved the validation of site recycling for construction waste as economic efficiency is analyzed through the case study of site recycling at large housing development district. Using the sensitivity analysis, factors affecting the cost of site recycling was analyzed and the break-even point for the cost of site recycling was estimated according to the factors.

This paper intends to analyze the roles of regulations and certifications within the construction market that affect the effective recycling and application methods of construction waterproofing industries. Certifications, eco-labels, green certification patents, and new excellent technologies obtained in construction waterproofing industries are studied. In accordance to the study results, it was determined that, a total of 38 items obtained eco-labels with effective recycling as the theme, 10 items with green certifications, and 8 items with New Excellent Technologies.

Recently, the construction wastes increase rapidly due to the revitalization of reconstruction and redevelopment, the development of new urbanization of large housing development, the expansion of social infrastructure, and so on. To solve rapid increase of construction waste, the government established "the rule on the promotion of recycling of construction waste" in December, 2003. According to the rule, construction wastes can be recycled by either processing on commission or discharger of construction waste. However, most of construction waste can be recycled by processing on commission. One of the most reason is that it is difficult for proving economic effect of site recycling by discharger. This study investigated and analyzed in a generation and disposal process, status of recycling, and procedure and process of site recycling of construction waste. Also, this study proved the validation of site recycling for construction waste as economic efficiency is analyzed through the case study of site recycling at large housing development district. The results of this study can utilize the establishment of policy and basic data of feasibility for site recycling of construction waste.

Nowadays, flooding wast is serious problem to mankind and the endeavour for solving waste problem is performed in connection with environmental problem and natural resource problem. In Korea, there are a lot of movements related to reduction of waste, too. As the solution of these problems, recycling is recommanded and many kinds of recycling technique are devised. In America, military has been playing an important role in recycling area for a long time. This paper is the survey of several articles and working papers about America military's recycling research. We investigated the recycling of water, construction and demolition wastes etc. These research results are very important in real field of military. It is considered our military has to prepare this recycling problem and now it's the right time. All of these can be adapted to our military, commercial companies and civilians through some modification. We suggest that our military should cope with recycling problem more deliberately.

Today's human life is more conveniently advantaged and abundant as industrial society advanced. However, the development has been creating a serious environmental crisis. Environmental pollution and exhaustion of natural resources recently became an important issue in construction industry as well as the concern about construction waste management and recycling the resources has arisen. Because the industrial wastes are not only increased quantitatively but also qualitatively intricate and various, groping for ways of reducing the use of resources primarily and recycling is urged on promotion. Currently, only about 33% of the wood wastes produced in construction site are recycled and the others are incinerated or disposed through irregular circulation process. In this study, I will investigate the present status of generating, processing, and recycling construction wood wastes and compare domestic disposal trend to other countries. In addition, I will analyze the actual condition of processing wood wastes in the construction site, verify the irrational causes, and simplify anomalous factors for the purpose of more efficient and correct activation of wood waste treatment and recycling on construction field and protection of environment in the long run.
