  • The purpose of this study was to investigate the environmental awareness and attitude of elementary school teachers. For this study, 100 elementary school teachers from H graduate school of education were sampled. The results of this study were summarized as follows. First, the biggest concern of environmental problems were water-pollution and garbage problems by the lack of understanding about the environment and injudicious development. Second, most teachers recognized the need for environmental education and they answered that they were doing best to teach students with the main purpose of helping them develop values of environmental preservation. Third, most environmental education was carried out during class using current events and the emphasis on garbage separation and recycling. They also showed the lack of teaching materials and field trips for environmental education. Fourth, it appeared to come from media-oriented environmental education. Most teachers mainly used newspapers and visual materials. 1'hey were obtaining knowledge and information related to environmental education through the media. Since in-service teachers' conceptions could directly effect present education, it is necessary to establish a more systematic educational system for environmental education, for in-service elementary school teachers.

  • This article deal with an overview of food waste treatment methods in Korea. Garbage trucks are operated manually by garbage workers who pick up the food wastes after food waste is placed in plastic bags by the road sides. However, there are a lot of problems such as, the smell from the split bags and the leachate, the loss of much energy and the complaints regarding the establishment new rubbish tips from the residents in the surrounding area. It also highlights our society's waste of resources. Although the new pneumatic waste transfer system or the dry method seem to have improved some of the environmental conditions, it still bears some problems, for example, the lack of reuse and recycling of resources and the economic problems. We have been analysed the advantages and disadvantages between the existing food waste system and the pneumatic waste transfer system. And the dry method and disposer were discussed. The results will indicate how the disposer can improve more than the existing systems and will provide the evidence to support.

  • A standard plastic garbage bag which was discarded from Incheon Metropolitan City was composed of 4.5% recyclable resources (aluminum cans 0.2%, steel cans 2.5%, glass 1.8%), 92.5% resources with recoverable energy (papers 23.0%, plastics 15.5%, combustible etc. 54.0%) and 3.0% non-combustible etc. Recycling is more effective than landfilling for aluminum cans, steel cans, and glass. The energy recovery process using solid refuse fuel (SRF) is more effective than incineration for papers and plastics. Incineration is more effective than recycling for combustible etc. 2,068,948 Million Btu of total energy savings and 21,008 $MTCO_2E$ of total GHG reductions were obtained by the application of the proposed scheme. The total energy savings were equivalent to an economic benefit of 422 billion won per year. The total GHG reductions were equivalent to a GHG benefit of 4,119 passenger cars not running per year. The lower calorific value of the combustible materials was obtained to be 1,936 kcal/kg of papers, 5,079 kcal/kg of plastics and 2,462 kcal/kg of combustible other resources, respectively. If papers and plastics are properly mixed, the mixture can be used as SRF. The lower calorific value of combustible other resources does not meet the quality criteria for refuse derived fuel, therefore its components are inappropriate to used as solid refuse fuel.

  • Anaerobic Digestion - Thermophilic Oxic Process(ADTOP) has been known to be one way reducing and composting of organic wastes without draining or forming excess sludge. It could be completely performed by the evaporation of water using the bio-energy from the microbial degradation of organic. In the present study the complete treatment of Chinese restaurant wastes was conducted and utility of bio-energy produced from the ADTOP was estimated. Base on results, it could be concluded as follows; 1) chinese restaurant wastes could be completely treated using the TOP without draining or excess sludge. Maximum volumetric loading rate was determined as $55.0kg-garbage/m^3$. Input water was almostly evaporated and 90.5% of carboneous organic wastes was conversed to carbondioxide. 2)The optimum volumetric loading rate which is acceptable to maintain over $55^{\circ}C$ in the anaerobic digester was determined as $45kg-garbage/m^3{\cdot}d$. 3) The optimum HRT was at least over 10 days in order to maintain about $50^{\circ}C$ in the anaerobic digester using bio-energy produced from TOP. Therefore the utilization of bio-energy produced from TOP could be used in the process which had long HRT such as the anaerobic digestion. 4) The efficiency of anaerobic digester rate were over 90% by the ADTOP under the organic loading rate of $1.1kg-COD/m^3{\cdot}d$, 50kg-Chinese restaurant garbage and $250{\ell}/m^3{\cdot}min$ of the aeration rate.

  • The enforcement of volume-rate disposal system which has been resulted in reducing the household waste and increasing the amount of recycled contents is showing positive effects that are generating social and economic benefits, However due to the lack of user's perception about how to separate and dispose of recycling wastes, some problems are constantly raised, like food waste is disposed in the standard volume-rate garbage bag. By rearranging visual information printed on standard plastic garbage bags (SPGB), this study attempted to find ways to deliver the information regarding how to use them properly. In order to achieve this, from the perspective of visual information design, the study examined the cases of visual information printed on nine SPGB from domestic and overseas. Among these, this study conducted a survey on user's awareness of visual information printed on SPGB in three districts of Seoul, Korea. As a result, user-preferred items were identified. Based on the result, this study selected information to be printed on SPGB, established the hierarchical order of the selected information, and proposed a guideline for using SPGB with informative graphics; therefore, the effectiveness of information delivery was improved. In addition, this study also examined the external validity of the guideline by comparing a survey on user's awareness.

  • The purpose of this research is study how housewives dispose unused medications in a household and produce basic research data that can be used to establish efficient recycling and handling of unused medications. Data collection was done using proportional sampling and survey was done in February, 2011. The unused medications in household consist of "tablets(58.4%)", "ointment(31.3%)" and "eyewash(22.7%)". The main way of disposing unused medications was "standard garbage bag(74.1%)". The ideal way of disposing unused medications was "returning to the pharmacy(57.9%)". Only 39.2% of people recognize about unused medications disposal system. In order to establish recycling and treatment of unused medications, it is necessary to create laws and regulations related to unused medications and allocate budget to actively promote the program to public. Most importantly, we must induce doctors and pharmacies to participate in the campaign and there should be laws to require them to explain to their patients how to recycle and treat unused medications when they give prescription and make preparation to them.

  • Waste policy instruments such as garbage bag-fee system and recycling policy initiated in 1995 have contributed to the reduction of solid waste generation. Rural areas now produce less amount of solid wastes in terms of per capital than urban areas and as compare to a decade ago. However, most policy efforts since the early 1990s related to waste issue have been concentrated in urban areas. Waste problems in rural areas are not the amount itself, but the specific characteristics which are unique in rural regions. Large portion of solid wastes and farming wastes are being illegally treated and/or burned out. Surveys show that the main reasons for the illegal treatment of rural wastes are th lack of systematic policy tools targeting on them, insufficient financial capacity and man power of local governments, rural people's cognition problem about wastes, among others. This study reviews current features of the treatment of rural solid wastes and provides policy suggestions for the resolution of the problem.
