Hue applies GIS to waste collection system

Associate Professor-Doctor Le Van Thang, Director of the Institute of Natural Resources, Environment and Biotechnology (Hue University) and his colleagues succeeded in building a GIS database on waste collection system .

Huong River and Thien Mu Pagoda in Hue

This is considered as a basis for evaluating the current status of waste collection system and providing data and processes to improve waste management by GIS technology.

GIS application to rearrange the waste collection system at the Nam Da Da planning sub-area, Hue city (Thua Thien-Hue), where there are 71% of waste bins are overloaded; 10% contains less waste; 53% unreasonable and 47% damaged, showing that 18 new garbage bins are needed; adjust 10 positions; keep 17 barrels; thereby solving the problem of garbage dumping outside the trash .

Application of GIS technology to rearrange the waste collection system for the whole area of ​​Southern Huong River in Hue city (Thua Thien-Hue) where there are 239 garbage bins with the rate of 6 garbage cans / km2, 666 people / trash bins, Overcoming inadequacies in waste collection in areas with overloaded garbage bins, garbage dumping on sidewalks, curbs, river banks .

GIS application based on spatial data, attribute data and mapping of waste collection system. The recycle bin system is arranged based on the results of the existing trash class space analysis.

Accordingly, the new barrel class is formed from two arrays: adjusting the position and positioning the new extra bin . Use MapInfo 8.0 software to combine two arrays and save them into new trash records based on specific characteristics of each sub-region at the same time, focusing on the application of spatial analysis in combination with methods of rapid assessment of sources generate waste and consult with the community to decide.

Application of GIS rearrangement of waste collection system helps to assess the current situation of the system of collecting and rearranging the garbage system in many areas; combine GIS technology with other methods to fully solve the relationship between collection system and impact factors; for high efficiency when creating a map, especially when required quickly and accurately ; overcome the disadvantages of traditional methods of garbage collection.
