Commercialized Operation Model and Development of Integrated Energy-Environment Engineering on Scaled Livestock Farms

This paper defines the concept of energy (biogas) environmental protection engineering on scaled livestock farms, which differs from large/medium scale biogas plants widely developed in China at previous time. Driven by pressure from environmental sector and demand for non polluted agricultural products, it stresses that the integration of waste treatment with its utilization and the integration of livestock & poultry breeding with planting. The paper states that anaerobic digestion as the key technology in the system is significant for effluent control of livestock farms. Barriers to widely extend this technology are analyzed in its commercial development. Finally a case of feasibility study on swine farms in Luoniushan District of Hainan Province is presented.
