Recently, the reporter learned from the Construction Bureau of Weifang City that Weifang City has implemented a franchise system for the transportation of construction wastes in order to effectively control the savage movement of dirt trucks, mud roads, spills along the way, and disorderly dumping. On May 5th, through open tendering, 7 of the 25 bid companies were granted the qualifications for franchising, and all 210 of their transport vehicles were converted and unified. In the next step, Weifang will also establish a dust pollution prevention and control system, which mainly includes remote monitoring of construction sites and a GPS monitoring system for transport vehicles, realizing real-time and dynamic management of construction and construction waste disposal, and further improving the level of information supervision.
