A food waste disposer is an electrically powered device installed under a kitchen sink. It is located between the sink`s drain and the trap which shreds food waste into tiny pieces so that they can go through plumbing. Use of this unit is convenient and hygienic for discharging food waste in kitchen. Nevertheless, this unit has been illegal until now in Korea because of both conflict with the government`s policy-resource recovery from food waste-and perceived threat to the city`s sewer system. An attempt was made recently to meet growing need to introduce this unit for advantage of using disposer and maintenance of sewer system, etc. So an attempt was made to introduce the food waste disposer system of ``treatment type before discharging to sewer``, but it was inappropriate for conditions in Korean. In this study, we developed a suitable disposer system for Korea based on an innovative solid recovery technology. And continuous operating experiments were carried out to evaluate the performance of the system for 18 days. The amount of food waste fed into the system was equivalent to the daily amount of food waste made from 30 households living in apartment units, which was calculated to be 14.44kg/day. After grinding, SS/TS of food waste was 60 percent and it was the maximum amount of solid that could be recovered using this system. In the system of solid collection type using screw press, more than 70 percent of suspended solids were recovered. And less than 20 percent of total soilds were discharged through wastewater and it satisfied the legal standard of Korea. This novel food waste disposer system will satisfy with both the government`s environmental policy and higher quality resource recovery from food waste in the facilities.
