Food waste disposer has been tried again in S. Korea. We examined the background and the considerations for the application of disposer in S. Korea. There are three considerations; disposer performance, plumbing design, and the method of wastewater treatment. Existed demonstration projects have not considered solid recovery. So, government set a new regulation of recovering more 80% of input solid or draining less 20% of input solid. In present, individual use of disposer with solid recovery kit has been accepted in law, however, that people use it without solid recovery kit is a problem. It needs to be converted to the use of apartment-building level for appropriate management and monitoring. New some demonstration projects has started including solid recovery concept and recycling solids on site or in existed recycling plants. However, present regulation of solid recovery rate is too strict, and so it is necessary to modify to the reasonable level.
