중국이 IT산업의 도약에 따른 채비가 한창이다. IT업계에서는 중국이 양적인 팽창뿐 아니라 질적인 면에서도 IT강국으로 불릴 만한 수준으로 올라 설 수 있을 것이라는게 대체적인 시각이다. 중국은 2001년부터 시작된 ‘10차 5개년 계획’을 통해 첨단산업 육성정책과 IT산업 발전지원정책들을 함께 실시해오고 있다. 거기에 발맞춰 경제편차가 심한 동서부의 균형을 맞추기 위한 ‘서부 대개발 계획’에 따른 서부지역의, 특히 중경의 IT산업 발전 현황 및 정책을 살펴봄으로서 우리가 나아가야 할 방향을 알아본다.

This study aims to suggest possible policy options for collection of post-consumer diapers as a sustainable prerequisite to implementation of public recycling system with the desktop monitoring results and analysis of collection cost involved. By conducting a diaper collection pilot test on daycare centers and households in the Seoul Nowon-gu, this study revealed that the odor issues did not stand out as an important hindering factor and that the collection rate was the largest contributing factor regarding collection costs. The exploratory cost analysis result shows that the implemented recycling system must guarantee collection rate over 50% via twice-a-week collection frequency, to be comparable or even superior to the current food waste collection cost. Also the pilot demonstration test showed that the final collection rate can be achieved as much as over 50%. The promising data thus obtained cost economically viable future diaper recycling system implementation in the entire Seoul metropolis and adjacent areas of dense population. With the concomitant development of recycling technology and related infrastructure for systematic collection of diaper waste, it makes our society much more sustainable.

Chemical catalyst products are applied to various fields such as petrochemical process, air pollution prevention facility and automobile exhaust gas purifier. The domestic and overseas chemical catalyst market is increasing every year, and the amount of waste catalyst generated thereby is also increasing. Most of the used chemical catalyst products, such as desulfurized waste catalysts and automobile waste catalysts containing valuable metals are important recyclable resources from a substitute resource point of view. The recycling processes for recovering valuable metals have been commercialized through some urban mining companies, and SCR denitration catalysts have been recycled through some remanufacturing companies. In this paper, the amount of domestic production and recycling of major catalyst products have thus been investigated and analyzed so as to be used as basic data for establishing industrial support policy for recycling of used chemical catalyst products. Also tasks for promoting the recycling of used chemical catalyst products are suggested.

Realization of zero waste society, which includes reduction, recycling and reuse of waste, has been a huge issue in Korea recently, and many experts are proposing various improvement plans in the establishment of political system. In particular, the current EPR system is partially agreed on its external achievement, but many problems are arising from the enforcement of the system. Therefore, flexible revisions and modifications on recycling policy are necessary. In order to understand the insufficiency and problem of the expansion of items in current EPR system, this study examined the actual generation and basic unit in small, medium and large-scale apartment complexes in B City and predicted the items that do not appear in the statistics to compare and analyze the problems in current recycling based on their result value; a survey was conducted on 137 experts and students of relevant major that live in B City on the items of EPR system and their perceptions to indicate the error in the necessity of items in EPR system that are generally underperceived by people and the error of current recycling system, and solution plans were sought to establish smooth future system.

The purpose of this study was to survey Suwon citizens over the age of 20 in order to provide basic data on the extent of coverage of the city's water reclamation system and to set guidelines for a policy on water reuse. The survey used a questionnaire with two fields, rainwater use and wastewater recycling, for analyzing factors that influenced water reuse. A factor analysis of 19 questionnaires gave a Cronbach's alpha coefficient greater than 0.4. Factors that influenced rainwater use were environmental protection, water charges, and the risk of climate change. Of the total explanatory power, the share of rainwater use and environmental protection was 39.7% and 28.1% respectively. Environmental protection (explanatory power 24.2%) had an effect on the explanatory power of wastewater reuse. When factors influencing wastewater recycling, like cost of recycling, water management policy, climate change, and suspension of tap water supply were included, the explanatory power of each of these factors went up by 4.3%, 2.8%, 3.3%, and 1.1%, respectively. For more effective wastewater recycling, a water management policy that factors in the above is required, along with a campaign to educate citizens on water management and environment conservation. Additionally, it may be necessary to improve the reliability and the quality of water supply.

A scrapped fiber-reinforced plastic(FRP) fishing vessel causes many environmental problems, because technology development for recycling FRP vessel has not been adequately addressed. FRP is a main material for constructing a small coastal fishing vessel that is an object of reduction policy. Therefore, the FRP wastes derived a scrapped fishing vessel are increasing. In this study, I investigated an effective disposal process for FRP through the analysis of the actual conditions of scrapped FRP fishing vessel. The treatment processes of scrapped FRP fishing vessel are carried out with oil-removing, dismantling, intermediated processing(crushing), and then reclaiming follows burning in the final processing in Korea. However, in Japan, several recycling methods have been developed, for example, the incineration including thermal recovery, the use of cement-reclamation, and the use of asphalt concrete aggregate, because the method of reclaiming after incinerating which is generally used in Korea produces a toxic by-product such as dioxin.

Along with the expansion of industrial activities, the quantity of industrial waste sludge is increasing, and the treatment/disposal of wastes is a social problem regarding the preservation of the environment. In particular, recycling the sludge as a raw material is actively required considering the situation of Korea, which is poor in natural resources and energy. Lime is a necessity for treatment of waste sludge, which often can be made recyclable by lime treatment. In this thesis, a brief description has been given of my views on the ordinary treatment of waste sludge and the effective use of inorganic industrial waste sludge focusing on lime.

This study is conducted to examine the ways to reduce the garbage amount by effective recycling food wastes in the cooking. The data is collected from 864 housewives who live in Seoul/Sungnam/Choongju by using questionnaires from 24 November 1997 to 5 January 1998. The results are as follows; The level of their needs of reusing food wastes in the cooking is high but the level of their participation and its satisfaction to reuse housewives is low. Especially they take part in reusing the garbage in pre-treatment less than edibile plate wastes. These factors result from lacking of their consciousness and knowledge of methods to reuse food wastes. Therefore it is said that consumer should make an effort themselves to participate in reusing food waste researcher should search the way to efficiently reuse the food waste and government should found the policy to provide information and education program for reusing food waste. The more seriously they perceive food waste reuse the mo e they want the way to accelerate food waste reuse by consumer researcher and government.
