Intensive pig farming in Centre China leads to the centralization of excreta .Chinese government has allocated lots of funds to construct biogas engineering for resource utilization of bio-energy in recent years. But investigation shows most of farms in rural areas discharge the residual product of anaerobic digestion directly due to the lack of consumers and funds, which has caused severe environmental pollution, and also endangered the development of farms themselves. In this paper, we have constructed a practical pig farming excreta recycle treatment model via a case study of the Lanpo intensive pig farming ecology system, and have conducted simulations with the corresponding dominant archetype. The results show that policies of encouraging more farmers to utilize biofuel, separating anaerobic digester effluent from irrigating water, developing the winter fallow cropland and the hilly land and governments’ fund and technology supporting may help shift the system toward sustainability.
