Objectives: In Korea, the system of management of medical waste largely relies on the incineration method. Our study aimed to identify any regional imbalances between the generation and treatment of medical waste, and provide reference data for future policy in Korea. Methods: We analyzed data on the amount of medical waste from 2,000 hospitals in 2012, 2013, and 2014 obtained from the Korea Environment Corporation. In the Arc GIS program (version 10.2.3), the addresses of hospitals and incinerators were transformed into map coordinates. The amount of waste generated by each hospital and the amount incinerated were represented by density and size of a triangle symbol, respectively. Results: As of 2014, the total amount of medical waste from the top 2,000 hospitals was 136,073 tons, out of which about half (49%) was generated in the capital area. Eleven incineration companies (three in the capital area, two in the Chungcheong Provinces area, one in the Jeolla Provinces area, and five in the Gyeongsang Provinces area) treated this waste. For the years 2012, 2013, and 2014, about 60% of the medical waste generated from the hospitals in the capital area was treated within the capital area and about 40% was transported to other areas, especially the Gyeongsang Provinces area, for treatment. On the other hand, about 90% of the medical waste incinerated in the capital area originated from the capital area. Conclusion: Our results suggest a spatial imbalance between the generation and treatment of medical waste in Korea and warrants multilateral policies, including the expansion of on-site treatment, strengthening regulation of the containment of medical wastes, promoting reductions in medical waste and more.

연구목적 : 종합병원을 대상으로 설문조사를 수행하여 의료폐기물 처리에 대한 문제점과 관리에 대한 개선방향을 찾고자 하였다. 연구방법 : 국내 326개 종합병원 중 응답한 기관 126개를 대상으로 온라인 설문조사를 실시하였다. 설문조사는 27문항으로 병원 및 의료폐기물 관리자 특성, 의료폐기물 발생현황, 의료폐기물 비용현황, 배출 및 수집특성, 자가처리 시행 경험 및 의견으로 구성하였다. 연구결과 : 가장 많이 발생하는 의료폐기물 종류는 일반의료폐기물로 매월 5톤 미만이 발생한다고 의료폐기물 관리자 60%가 응답하였다. 일반 쓰레기통에 의료폐기물이 버려지는 경우가 있다고 응답한 경우는 23% 반면에 의료폐기물 전용용기에 일반쓰레기가 버려진다고 응답한 경우는 55%으로 조사되었다. 또한 처리비용은 지역과 위탁처리업체에 따라 차이가 있었으며 대부분의 종합병원(93%)이 의료폐기물은 소각 하는 것이 가장 안전하다라고 응답하였다. 결론 : 의료폐기물 발생량 감소를 위해 일반쓰레기와 의료폐기물의 엄격한 분리수거가 필요할 것이다. 또한 처리비용에 대한 표준안 제시 등 정책적인 방안과 새로운 기술에 대한 평가 및 다양한 처리방안에 대한 연구가 선행되어야 한다. Objective: Collecting actual data on the current status of medical waste management in general hospital is essential for establishing effective policies for medical waste management nationwide in Korea. Methods: Total 126 out of 326 general hospitals in Korea participated in the on-line survey. The survey questionnaire comprised of 27 questions on the current status of medical waste management (segregation between medical waste and municipal solid waste, and cost of medical waste disposal) and opinion about on-site treatment. Results: Over 60% of general hospitals generated at least 5 tons per month and most common type of medical wastes were general medical waste. Even though separate containers are used for collecting medical waste and other municipal solid waste, the latter tend to be thrown into the container of medical waste (55%) and vice versa (23%). Disposal cost of medical wastes varies very much significantly by region in Korea or by the entrusted company for medical waste disposal. Almost all managers for medical waste in general hospital (93%) thought that incineration is the safest option for medical waste disposal. Conclusion: The results of our study suggested that the amount of medical waste could be reduced by accomplishing strict segregation between medical waste and municipal solid waste. Certain guideline is necessary for disposal cost of medical waste by the government. In addition, a number of technologies developed for on-site treatment should be evaluated in terms of risk for potential infection in advance to expand on-site treatment.

In this study, the optimum operating condition of the molding machine included in the mobile solid fuel production system which produces the solid fuel from the collected coastal waste was analyzed by the response surface analysis method. Most of the coastal wastes are flammable and consist mainly of nets, ropes, buoys, styrofoam and wood. However, it is treated as landfill, consignment treatment or illegal incineration after on-site collection, resulting in serious secondary contamination. For this reason, a new portable moving solid fuel production system is currently under development and aims to establish optimal operating conditions for the system. The discharge port temperature (℃), Revolution Per Minute(RPM), and waste PE content (wt.%) Of coastal waste were set as independent variables and the molding density (g/cm3) was set as the dependent variable. It can be confirmed that the pellet density increases as the discharge port temperature and the pellet density as the screw rotation speed decreases. We also found that the PE-based coastal waste content does not affect the molding density.

Objectives: Because the amount of medical waste (i.e., health-care waste) generated in Korea is rapidly increasing and social concern against its safety is widespread, a number of issues related with medical wastes are being discussed. The purpose of this study is to compare diverse medical waste management systems worldwide and propose future directions of a medical waste management system in Korea. Methods: Literature review was conducted mainly on the WHO, and developed countries such as the European Union (Germany, Belgium and UK), Japan and the United States. For these countries, the data with respect to their systems for medical waste management ranging from the definition of medical waste to the whole processes of collection, transportation and disposal were summarized and compared. Results: The terminology and classification of medical wastes were not consistent for WHO recommendation, EU, Japan, US and Korea. Comparison of the collection, storage, transportation and disposal of medical waste showed that Korea had rather stronger regulations for medical waste management compared to developed countries including Belgium (Flanders region), Germany, Japan and the US. Considering that developed countries adopt rather flexible disposal system especially for general medical wastes which pose lower possibility of infection, Korean government could consider diversifying disposal methods other than incineration. It may also be very important to try to reduce the amount of medical wastes and enough capacity for off-site incineration are secured. Conclusion: Our study of international comparisons suggests that it is necessary to continue to identify advantages and disadvantages of the current medical waste management systems and establish more effective one in Korea.
