Abstract
Over the last decade, urgent problems related to the waste management system of Da Nang city have been recognized. Therefore, research on the current status of solid waste management system and solid waste collection system is gradually becoming paramount. This study applied Geographic Information System (GIS) and Global Positioning System (GPS) to study the current status of the waste collection system in Hai Chau district, Danang city. The GPS devices were utilized and in-depth interviews were also performed to collect information and data about the waste collection system. Data were synthesized, processed, and analyzed by QGIS 3.4 and Excel 2016. Four teams were in charge of solid waste collection in the entire Hai Chau district. The average daily amounts of solid waste collected were 56t (Team 1), 42.4t (Team 2), 42.6t (Team 3), and 61.1t (Team 4).
