With the rapid development of science and technology and the global warming caused by climate change, the extreme climate and the global plate have frequent effects, which not only seriously influence on the ecological environment, but also the shortage of natural energy caused by over-exploitation of human beings. Various countries have recognized nowadays the importance of energy and carbon dioxide emissions reduction, and with the development of circular economy issues, the governments realize that waste water discharged from high-value animal husbandry is a reusable resource. The environmental protection agencies cooperate with other agricultural institutions together in order to promote the policy of “returning fertilizer to the field”. However, urine water will produce biogas during the treatment process. Its main component, methane (CH4), is 25 times more than carbon dioxide (CO2), and the greenhouse effect caused by methane is carbon dioxide. But if the relevant technology is purified, methane becomes a good source of heat energy. If it is introduced into the generating set, it can become the daily electricity demand. For example, the principle of biogas power generation is to use the pig’s excrement anaerobic and fermentation, then the gas generated in it is introduced into the generator to diversify energy utilization and make the effect of room gas reduction.In Taiwan, there is a unique geographical environment. The temperature is moderate and humid all year round which belongs to the maritime climate and makes all kinds of poultry grow well. The domestic stock farming output value accounts for about 30% of the total agricultural output value, and the pig industry value accounts for about 15% of the total agriculture, showing the importance of the pig industry in Taiwan. The government is responsible for taking care of the livelihood of the majority of pig farmers, taking into account environmental protection responsibilities, promoting agricultural and enterprise management, and raising green energy pigs. Marsh gas power generation is relatively stable compared to wind and solar power. It does not have to depend on the weather and it can also supply electricity during peak hours. For example, Denmark began the research 40 years ago. Marsh gas is not only the excrement of pigs, but also Cattle and sheep chicken manure, kitchen waste, animal carcasses, etc. In the process of bacteria decomposition of organic matter, it will release the main substances of biogas containing methane, carbon dioxide, hydrogen sulfide and other gases. In the light of this, the Industrial Technology Research Institute Branch in Taiwan has established the Office for Biogas Promotion Program in 2016. They actively promoted biogas promotion services, and gave relevant technology and knowledge to explore new energy opportunities and activate related industries.The international survey report pointed out that between 2050 and 2070, the main energy sources for human beings will gradually dry up. Therefore, the application of recycling economy and resource reuse are much more important. This researchers invited “ Universe Circular Technology” as the subject and we will discuss how enterprises respond to the government’s promotion of circular economy policies, realize the new agricultural development that the government vigorously promotes, and use the regeneration of resources to solve the problem of energy shortage in Taiwan.
