차량수거 곤란지역의 음식물쓰레기 수거인력 평가 - A지역을 중심으로 -

Abstract

Generally, collector requirements in wastes gathering are measured by 'loading time' per weight or per wastebin. This man·hour or loading time indicator, however, barely reflect seasonal variation, daily fluctuation, and neighborhood characteristics that greatly influence wastes volume. This study tries to examine a new indicator which can closely estimate numbers of collectors. Focus is placed on the field survey used a new indicator, 'total distance in waste collection' to estimate the numbers of waste collectors more accurately. Information and data as well as numerical expressions are also provided. A field survey is performed. The subject area of investigation includes detached housing alleys in an autonomous ward in Seoul. A result of new 'distance' indicator calculates 17,200 meters of an average daily walked distance per collector, 43 meters per minute of an average speed, and 1 to 1.9 of an average ratio between walked distance to straight distance of the alleys. Applying new 'distance' indicator, it can be easily measured the actual alley distances by GIS maps without cumbersome field surveying of the distances. The detached housing areas in the autonomous ward as a whole are required 9.17 collectors to haul all food wastes every two days a week. The collectors are proportionally needed by frequency in collecting wastes. By contrast, numbers of collectors resulted from loading time per weighed wastes
