This study has been performed for the purpose of clarifying the actual state of "refuse disposal", "refuse disposal facilities" and "volume of refuse produced" in the office buildings. The results obtained are as follows; There is a : 1. The flow and the classification of refuse produced in the office buildings are in general as shown in Fig. 1. 2. The dust chute has such difficulties as stated below. a. Fire is liable to break out. b. It is as a whole apt to be a smoke duct at the time of fire. c. It is liable to be a source of birth of harmful insects. d. The dust collecting work in the dust pit is inefficient and not sanitary. e. Heavy weight substances will cause shocks when being dropped. f. The voluminous dust such as scrap paper is difficult to be cast in the dust chute. 3. The incinerator has increasingly been unpopular due to the following reasons : a. The personal expeditures run up to a large sum. b. It will be a cause of environmental pollution in urban area. c. The conventional type of incinerator is not sufficient for the increase of refuse comprising plastics, etc. d. Thanks to the appearance of shredders the need to burn up confidential papers is on the wane. e. The incinerator is liable to be a source of fire accident. 4. The dust press is a machine to compress and solidify the waste mainly composed of scrap paper to 1/4-1/5 in volume. Although convenient for storage and transportation of dust, the press has still such shortcomings that the press operation is troublesome and the reclaiming of scrap paper can not be performed. 5. The refuse cooling compartment is a room where refuse is kept at low temperature for the purpose of preventing putrefaction of refuse, generation of offensive smell and birth of harmful insects from being accelerated. 6. The refuse storage facility is that which keeps for a certain duration of period the refuse classified as per the day of production, so as to be able to find out the necessary papers and documents lost among refuse. 7. The volume of refuse being produced per 1, 000 persons in the office buildings amounts to 2.5-4.0m^3 per day. 8. The composition of the volume of refuse by classification will be about 5 for refuse packed in hempen bags, 3 for refuse out of containers and 2 for that in containers. Of the refuse in containers, the feed for the domestic animals to be taken away by the livestock producers will occupy about 15 through 40%, but the larger the buildings, smaller the ratio. Of the above refuse out of containers, namely the solid refuse the quantity to be taken away for reproduction by paper material dealers will be about 30% and is mainly composed of empty corrugated card board boxes. The waste to be taken away for reproduction (including the feed for domestic animals) will be about 60% of the total refuse being produced. 9. The volume of refuse being produced in a day is almost constant throughout a year except on Sunday, Saturday and national holidays. However, on the 30th day of December the refuse two or three times larger in volume than in an ordinary day is produced. It is also said that the waste is especially large in quantity on such a day as a tenant moves out.
