To upgrade "reduction, recycling, and harmlessness" of waste disposal, to innovate a new model of waste collection, transfer, and disposal, and to explore a new method of environmental protection in the Erhai, Dali, based on the idea of "scientific treatment, leading technology, integration of urban and rural area and market-oriented", the advanced technologies and adopted market-oriented operation have been introduced. In June 2012, we invested 110 million RMB in the form of BTO (Build-Transfer-Operate) to build 10 waste transfer stations with the advanced and mature treatment of “up-feeding horizontal direct compression” and “large pull-arm hook truck transferring” in two districts in the Erhai basin and 11 towns in Xiaguan and Dali, purchasing 15 waste transfer trucks, 111 small waste collection trucks, and 1,002 waste collection boxes.
In July 2013, the information management system for domestic waste collection and removal treatment was completed. The weighing data and video data of each station could be transmitted to the information center in real-time, and a GPS positioning system was installed for the waste transfer vehicles. The weighing data is used as the main basis for waste collection and transfer subsidies and the government's payment of enterprise operating costs, the video data could realize real-time monitoring of the waste compression and disposal, and ultimately achieve the goal of "digitalization, videoing and positioning" of the whole urban and rural domestic waste disposal.
This project has been honored by the Ministry of Environmental Protection as the "Key Project of the Ecological Environment (national level)", the Ministry of Housing and Construction as the first successful "model project of urban-rural integration (rural continuous improvement) waste collection and transfer system", and the National Development and Reform Commission as the only "representative and exemplary PPP project" in the field of environmental protection in the first batch (13 in total) of domestic waste collection and transfer in China, and all parties concerned were called upon to actively learn from it when participating in PPP projects.
