Abstract: For sustainable agriculture to maximize resource utilization, a biogas generation technology by integrating the solids-liquid separation, methane gas generation, and fiberglass-reinforced plastic biogas storage into a system for waste treatment at swine farms was designed and evaluated. The combined system with automatic controls could be scaled up for large biogas production applications. The experimental model was implemented for observation and testing at Xinxing Pigs Breeding Co., Ltd. in Fujian. The results showed significantly improved yield and utilization efficiency of biogas as compared to the conventional devices. The technology was expected to become a model for practical ecological sewage treatment for effective agricultural recycling at swine farms.
