Abstract
The characterisitics on waste disposing behavior and the unit weight distribution of combustible waste bag was conducted, which was based on the amount distribution of waste bag in one district in Fukuoka city, Japan. The weights on the waste bag were measured to clarify the actual status on the waste disposing. As a result, any people reduces the waste disposing frequency not from the bother on the waste disposing but from the adjustment of the density of waste bag. Many people decide the size of waste bag in advance based on the amount grasping from the long time experience. The unit weight on waste bag was recognized 0.10 - 0.12 kg/L as full.
