In this study, we aim at the workplace which is report target about person who emits much food waste, apartment house and detached house. We respectively selected 3 places in this study. Density of average complex bad odor which is generated in storage container of food waste appears high in order of workplace(2,523.8 OU/m3), apartment house(2,135.7 OU/m3) and detached house(1,556.5 OU/m3). And then, it doesn’t seem like big difference. However, these appear degree of bad smell intensity which is more than 3. Meanwhile, bad smell intensity about 3 same occurrence sources which are classified (three places which are respectively workplace, apartment house and detached house)appears big difference. Therefore, we must completely follow the meter-rate system of food waste to reduce the bad smell intensity of storage container of food waste. Also, we must use verified products in order that quality of exclusive storage container prohibits leakage of bad odor. And then, we must periodically clean the storage container and sterilize it. In addition, when we discharge food waste, we must decrease moisture content to squeeze included water. Also, we must make an effort to reduce storage period , as much as possible. And then, it is necessary to prepare countermeasure about this.

Research was conducted on the characteristics of waste discharge in apartment houses with less than 200 households. Implementation of the meter-rate system of food waste for apartment houses was also investigated and an economic evaluation was carried out to reach the following conclusions. First, for the monthly characteristics of the overall amount of food waste in apartment houses with less than 200 households, December and January exhibited the maximum amount while February and March exhibited the minimum amount of discharge. The average amount of waste discharge per household was the lowest at 0.51 kg/day · household in apartment houses with 20 to 50 households, followed by 0.80 kg/day · household in apartment houses with less than 20 households and in apartment houses with 50 to 100 households. Apartment houses with 100 to less than 200 households had 0.71 kg/day · household of average waste discharge. The results showed that the amount of food waste discharge is dependent upon the economic conditions or environment of the regions concerned rather than upon the number of households. Second, two meter-rate systems of food waste were compared: the RFID system and the Chip system. When the comparison was made under the same conditions for the number of households in apartment houses in which meter-rate system was being implemented, the average reduction rate in the Chip system was 21.1% and that in the RFID system was 57.1%. A comparison of apartment houses under the meter-rate system and of apartment houses with less than 200 households with apartment houses with less than 20 households, 20 to 50 households, 50 to 100 households, and 100 to less than 200 households showed that the average reduction rates of the Chip system and the RFID system was 35.3% and 61.9%, respectively. Last, a comparison of the results of the field study and the rate of food waste reduction in regions where the meter-rate system was being implemented showed that the average reduction was 35.3% for the Chip system and 61.9% for the RFID system, with a difference in reduction of about 35.5%. In the case that the RFID system is adopted, the disposal cost of about 62.7 billion won per year would be reduced by about 19.4 billion won, which leads to a prediction of a reduction in disposal cost to about 43.3 billion won per year.
