Solid waste management in urban areas of Vientiane Capital City using GIS

The purpose of this project was to research solid waste management in urban areas of Vientiane Capital City; to survey about waste collection, composition of waste and recycling for the economy; to establish waste data for monitoring and management using GIS; to improve aesthetics of the city and increase public awareness. The map created by geographic information system (GIS) was proposed to generate GIS database of solid waste with data entry of the details - spatial and attributes - bins, routes, quantity of dry waste etc. The analysis techniques were composed of database generation and map visualization. Map overlay techniques were used to study the general sources of solid waste and waste distribution boundaries. The waste collected by the Vientiane Cleaning Unit under the Vientiane Urban Development and Administration Authority, and waste pickers is thought to be different from the landfill waste. There is a lack of a data sharing and also a lack of database generation using geographic information system. Therefore, good methods of waste management and appropriate technology are needed to improve this trend.
