The move was made because in recent days, dust from Long Thanh airport has spread to residential areas and highways, affecting people's lives and vehicles. Dong Nai Provincial People's Committee and the Ministry of Natural Resources and Environment have requested ACV to have a solution to limit dust dispersion outside the construction site.

At the same time, the supervisory force also requires vehicles to go on official roads and not cross vacant lots during construction activities.

This investor explained that this technology is not yet popular in Vietnam, so it has not been considered for application. On the other hand, with a large area of up to thousands of hectares and many areas under construction of project infrastructure, applying the above technology requires a lot of costs.
