The garbage emitted from households and industries has constantly increased for the recent years, and its treatment cost has been financially burden to the municipal government. Many municipal governments recommend their households to purchase household garbage processors in order to reduce the volume of garbage transferred to and incinerated at their facilities. Actually, there are 1,535 municipal governments, which subsidize their households to purchase electrical garbage processors and/or containers. These subsidies should be assessed from various points of view such as cost and benefit of municipal governments and households, and also global or local environmental loads. An environmental planning department of a city office sent questionnaires to households to investigate utilizations of subsidized processors and/or containers. An environmental organization of citizen supported the department with designing a questionnaire form and analyzing data collected by the questionnaire. In this paper, the processes of designing the form and analyzing the data are explained, and then the evaluation of the subsidy is presented. The conclusions are as follows: Electrical garbage processors would be beneficial for local environmental problems such as lack of final landfill site. However, the processors would increase the CO2 emission, unless the electricity consumption can be improved.
