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.

The present problems concerning the control of generation, storage, collection, transfer and transport, processing and disposal of the municipal waste are serious. And the transportation of the municipal waste is recently a important part of solid waste treatment and disposal. The waste pneumatic transportation system is expected to be an effective method for use in solving that problems. In this study, pneumatic transportation system was applied to 2,000-5,000 households of public/group housing for economic and technical analysis on the basis of data for working and operation. The proper equipment must be selected through economic and technical analysis for generation and properties of waste because the equipment in facilities of system is various. And the efficient operation method should be studied on the basis of information on the record of oeration. As the wet food waste clogs the pipeline, it is necessary to examine under the actual condition. The maximum unit waste generation rate based on the assumption that each household is comprised of 3.20 people is determined $2,340g/household{\cdot}day$, and it is included the 50% increase of seasonal and daily change.
