An EPJ process simulation model was set up and verified to simulate the plasma gasification process of the medical wastes. The influence of ER value and SAMR value was simulated based on experimental conditions including material feeding rate, furnace temperature and medical waste properties. Results shows that ER=0.3 is a turning point for medical waste plasma gasification. The required input plasma power and volume flow of combustible constituents in syngas reach the maximum at ER=0.3. The balance of syngas composition and required input plasma power should be overall considered. Results shows that the SAMR value mainly influences the amount of H element and N element in the system at a fixed ER value, thus influencing the proportions of H2 and N2 in monotonous ways. Input plasma power needed and combustible syngas flow increase with the increasing SAMR.

This research was conducted for the purpose to overcome Indonesia waste problem. The samples are classified into garden waste, paper waste, wood, food waste, and MSW with objective to identify which type of waste give out more syngas since there is waste separation in Indonesia. All samples were treated by plasma gasification without pre-treatment (drying). Arc plasma torch used in this experiment was made by National Nuclear Energy Agency (BATAN) and used Argon as the gas source. Then the torch was connected to self-designed gasification chamber and gas washing system before injected into a gas bas for composition analysis. Another objective is to identify factors that may affect the gasification efficiency and the experiment shows that moisture content is not really affecting the efficiency but the duration of the process. The mass reduction of each samples were recorded, then the gas produced from the gasification process were analyzed. The result shows that food has the highest mass percentage reduced and producing the highest amount of hydrogen amongst other samples. However, treating MSW also produce considerably high amount of hydrogen. In conclusion, MSW direct treatment (without separation) using plasma gasification is feasible since it still produces desirable quality of syngas.

The article shows that in the daily activities of nursing staff of functional diagnostics departments (offices), it is necessary to strictly observe the requirements and rules for the prevention of infections associated with medical care, especially during the COVID-19 pandemic. The types of personal protective equipment (PPE) of medical personnel (MP), as well as current effective methods of disinfection, rules for collecting medical waste in a complex epidemiological situation are presented.

Objective: Monitoring and evaluation of air environmental quality, waste water and medical waste management activities in some hospitals in the Central Highlands. Research Methodology: Cross-sectional descriptive survey was deployed in 6 provincial hospitals of the Central Highlands in 7th- 8th months every year for 3 years, 2011, 2012, 2013. Observing the process of waste management in hospitals, weighing the medical solid waste generated daily, sampling and environmental monitoring of air, water waste samples after treatment of hospitals. Findings: The percentage of substandard sample of radioactive 2011 was 5.88%, in 2012 was 5%, 2013 was 0.02%. Mainly in dose laboratories, rinse the nuclear medicine department, hatch covers radioactive waste storage. 100% of the air sample of wastewater treatment areas have NO2 target and 60% of SO2 target sample have not reached allowed regulations. The atmosphere at the garbage area hospitals in Kon Tum and Lam Dong provinces through 2 years of monitoring in 2012, 2013 exceeded SO2 target standards. Monitoring results incinerator emissions sample at 3 hospitals: Kontum, Gia Lai, Dak Nong in 3 years reached Regulations allow. The observation sample treated waste water of the hospital in 2013 with low contamination rate than in 2011 and 2012 in terms of physics and chemistry. Particularly criteria Total coliforms 3 years are from 40-50% of samples exceeded standards. Regarding waste management, the results of monitoring in 2013 showed that 60% of faculties have sharps instruments and 20% of the faculties have satisfactory utensils anatomical waste. 59.48% of the faculties have the guidelines for waste separation. Condition misclassified not many and occur in two hospitals Gia Lai, Dak Lak. Only Lam Dong hospitals have waste transportation vehicles secured closed during transport. The amount of waste / beds / 24 hours is 1.097kg. In particular infectious waste is 0.26kg. Only two hospitals in Daklak, Lam Dong has generated radioactive waste with a total of 0.9 kg/day. Key words: Medical waste, medical waste management.
