| Abstract | Pig breeding pollution has become one of the important sources of environmental pollution, and the circular economy has provided an effective way to alleviate the pollution of pig breeding. In this paper, the "Three-in-one" and "Four-in-one" mode of circular economy with methane as link were constructed, and taking Liaoning Province as the research area, the economic benefits of different pig breeding modes were compared and analyzed. The results show that: (1) The modes of circular economy use the pig manure waste as raw materials through the digesters, solar greenhouse to generate new resources, compared with the traditional farming methods, created considerable economic benefits and also alleviated the pressure of pollution, is an effective way to control the pollution of pig breeding. (2) The economic benefit of the "Four-in-one" mode in Liaoning was much higher than the "Three-in-one" mode. The economic benefits of biogas digesters were higher than the "Three-in-one" mode of 125 million yuan, while the solar greenhouse would introduce the planting industry into the recycling chain, with a net profit of about 38. 64*108yuan. |
