  • In order to survey the numerical achievement of ELV recycling rate 95%, the definition of ELV recycling rate, material components of the automobile, improvement of ELV dismantling technology and status of ASR recycling were reviewed. On the other hand, field survey in details for dismantling works were conducted at Incheon Junkyard and H Junkyard. Although material recycling rate has been approaching 94% in dismantling step, status of ASR recycling is very unstable due to a ban of ASR recycling at cement kiln. It is clear that ASR recycling acts as a bottle neck in the ELV recycling. Therefore, it is important energy recycling of ASR should be enlarged to achieve ELV recycling rate 95%.

  • In order to prospect current recycling status in Korea, legislative system and policies relating to recycling, wastes generation and recycling rate were reviewed. Approximately 260,400 ton/day of wastes was generated in 2001. 48,400 ton/day of household waste and 212,000 ton/day of industrial waste. During the last ten years, waste management laws such as waste disposal law, recycling law and environment friendly industry law were prepared. In this article, concerning over waste generation and recycling, recycling law, Extended Producer Responsibility System and the problems and technological developments associated with recycling were summarized.

  • The purpose of this study is to examine consumer characteristics according to the recycling behavior and analyze the affected variables on recycling behavior. For the empirical analysis, the data was collected 585 consumers from May 14 to June 8,2001. The statistical methods for this study were descriptive statistics, t-tests, cross tables, ANOVA and multiple regression analysis using SPSS PC program. The major findings of this study were as follows: 1. Convenience was important variables to explain the recycling behavior of household trash between two groups, but extrinsic incentives of rewards for undertaking the behavior was not significant. 2. Intrinsic motivation like as perceived consumer difficulties(PCD), perceived consumer effectiveness(PCE), recycling altitude, and ethic was significant variables to compare two groups. 3. Recycling knowledge was important to explain the recycling behavior, but no impact on recycling behavior. 4. Except age, all of socially demographic variables were significant to compare the recycling behavior of two groups. 5. Recycling attitude and convenience had influence on recycling behavior. Especially, ethic had influence on low level recycling behavior of consumer group.

  • In order to investigate the influence of recycling, a laboratory method simulating the papermaking process was used for assessing the effects of recycling on fiber properties. Sw-BKP, Hw-BKP and BGP were disintegrated and beaten to about 42$^{\circ}$SR-44$^{\circ}$SR by a valley beater. After beating, these pulps were dewatered by centrifuge and dried at 90$^{\circ}C$ for 72hrs. This recycling process(sequence of wetting, defiberating, dewatering and drying) was repeated seven times. Physical, mechanical and optical properties of recycled pulps were evaluated by TAPPI Standards. Morphological changes occurred through recycling process was observed by SEM. Sheet density decreased with recycling. The largest drop in density occurred during the first recycling. The porosity values decreased with recycling. Mechanical properties such as tensile, burst strength and folding endurance, decreased with recycling. However tear strength of Sw-BKP and mixtured pulp increased at the first recycling. Optical properties such as brightness, opacity and light scattering coefficient, increased with recycling. However, brightness of mixtured pulp gradually decreased with recycling. Fibrillated outer layer of the fiber was gradually removed from the surface with recycling. As a result of recycling, crinkles on the fiber surface were found to be more folded.

  • To investigate the necessity and background of the metal recycling from urban mine resources, 4 bigger problems such as the limitation of the underground resources, consumption of the metal resources, contamination of environment and metal recycling business were reviewed. Waste management and recycling are the foremost issues facing Korea on its path to sustainable development in the 21st century. Especially, metal recycling from urban mines is the most urgent fact for global environment and resources conservation. In order to build a recycling-oriented society, it is necessary to develop the recycling technology, recycling practices and a recycling-oriented economic system.

  • In order to review the recycling status of urban mine resources in Taiwan, background and history of recycling industries, system of the recovery fund management committee(RFMC), copper recycling with non-ferrous metals, recycling of ELV(end of life vehicles) and recycling of EAF dust were surveyed. Taiwan is a leading country of the world in the metal consumption per capita. Therefore, a lot of waste metals were generated. In other words, urban mine resources are abundant in Taiwan and have some advantages in recycling. There are more than thou-sand recycling plants in Taiwan. Half of them are non-ferrous metal recyclers.

  • This study, focused on reuse of the concepts of unused clothing recycling, was intended to provide basic materials and suggestions for establishing the drastic measures necessary for consumer education related to recycling by investigating how experiences in the recycling of unused clothes would show up according to environmental consciousness and recycling consciousness and then probing the scheme for the recycling of clothes. Since it was found that recycling consciousness was the variable that exerted a great effect on experiences in recycling unused clothes, consumer education about recycling will have to be revitalized. And detailed and specialized education on environmental consciousness is more important than emphasis on the importance of environmental consciousness.

  • The purpose of this study was to examine the effects of social norms and personal ethics on recycling behavior. For this purpose, survey data from four hundred and fifty seven individuals were collected and analyzed using an SPSS program. The major findings were as follows: First, social norms had a positive impact on personal ethics and recycling behavior. Second, personal ethics significantly affected recycling behavior. Third, awareness of the consequences of recycling behavior (AC) and ascription of responsibility for environmental problems(AR) did not significantly translate personal ethics into actual recycling behavior. Fourth, ascription of responsibility for environmental problems(AR) and awareness of consequences of recycling behavior(AC) affected recycling behavior. These results suggest that in order to encourage recycling behavior, it is necessary to inform and educate the public so as to enhance social norms and personal ethics.

  • 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.

  • Prior to discuss on recycling status and future prospects for the non-ferrous metals in the Korea, Japan and U.S.A. respectively, worldwide resources of non-ferrous metals and characteristics with recycling of non-ferrous metals are reviewed. In case of recovery non-ferrous metals, recycling of automobile shredder dust and E.A.F. dust are illustrated. Finally, the problems and technological developments associated with recycling of non-ferrous metals are summarized.
