The Waste Flow Diagram (WFD) estimates the amount of solid waste entering nature and the oceans from various sources. A scenario function is used to simulate how improved waste management could reduce pollution and prevent marine litter.
Huế city is located in central Viet Nam with the Perfume River running through it and leading to the East Sea.
The population was estimated to be 488,157 people in 2020, prior to the 2021 administrative boundary extension with the Extended city area now encompassing 266km². The WFD was carried out for both the Core and Extended areas which included collecting samples from 9 wards and communes including 6 in the Core area and 3 in the Extended area of the city.
The extension of the city resulted in an urgent need to assess its MSWM system and reduce plastic waste. This included undertaking the WFD in order to build a database and implement the project “Huế city – A Plastic Smart City in Central Viet Nam” which aims to improve their MSWM system.
