The Project Development Objective (PDO) for the Hebei Rural Renewable Energy Development Project in China is to demonstrate sustainable biogas production and utilization to reduce environmental pollution and supply clean energy in rural areas of Hebei Province. This project is made up of two components. Component 1 is labeled: Large-scale biogas facilities management and renewable energy supply. Under this component the national and international best practice in developing large-scale biogas facilities will be introduced and demonstrated. Six biogas facilities will be installed and operated in Hebei, as six investment subprojects, to effectively convert agricultural wastes (specifically crop residues and livestock manure) to biogas and to provide stable clean energy to local rural residents. The subprojects are located in six project counties, namely Anping, Yutian, Zunhua, Linzhang, Chengde, and Laoting counties. Component 2 is labeled: Technical support, project management and monitoring. This component will support technical services, training, monitoring and evaluation, and project management. Specifically, (a) an expert team will be contracted by Provincial Project Management Office (PPMO) to provide technical assistance for project implementation; (b) for each subproject a sample laboratory will be established for stabilizing day-to-day biogas facilities operation by analyzing and controlling fermenting conditions of biogas digesters and testing biogas and slurry; (c) a monitoring system will be established both at subprojects level to monitor their individual biogas system operation and at provincial level to monitor overall project biogas system operation, project performance and its impacts; (d) around 1,800 person-day training will be arranged for project technical and management staff at provincial and county levels, in particular for the local technical s
