The findings of hearings and questionnaire surveys regarding waste collection points in municipalities are given in Part 1 of this report. The regulations for waste collection points varied by municipality, and within custodial spaces, each municipality had different regulations, especially regarding recyclable items. In the present report, a survey was conducted to ascertain the actual conditions of waste collection points at office buildings, and a waste collection planning method that supports resource recovery is proposed based on the those results, with the following findings.
1) According to the survey, even among buildings reporting adequate space for waste collection points, respondents reported insufficient working space for waste separation.
2) There were about 11 separated waste groups at surveyed buildings after excluding waste groups specific to individual buildings. Of the various separated waste groups, groups for paper, cans and bottles were established at all buildings, but there were differences in the handling of types of plastics.
3) When investigating custodial space use, it is important to account for the apparent specific volume of waste, the differences in storage containers, and the number of separated waste groups.
4) With the proposed planning method, by selecting proper storage containers based on waste volume and properties, custodial spaces can be arranged in a rational manner to ensure sufficient working space for waste separation.
