However, alternative energy sources to wind and solar power should be pursued to facilitate stable electricity supply in Taiwan. Moreover, as industries in Taiwan heavily rely on export for revenue, carbon deduction strategies should be explored to alleviate the impact of a global pursuit of clean production and carbon tax. Under the framework of net-zero emissions, greenhouse gas (GHG) emissions from one industry can be deduced from another industry in a country. Since animal husbandry is prosperous in Taiwan, the derived biomass and animal waste require proper treatment. If the biomass and biowaste can be properly treated and reused as resources, we can simultaneously relieve the energy, environment and industry issues facing Taiwan. Taiwan’s pig industry accounts for more than 13% of the agriculture production revenue. There are approximately 5.5 million pigs in Taiwan, and the derived waste such as pig manure is significant. In turn, the biogas produced by anaerobic digestion (AD) of the biomass and organic waste, which contains over 60% methane, is an indispensable resource in the future. Therefore, this project aims to evaluate carbon emission reduction potential of the AD process for pig manure in Taiwan. We established two scenarios for analyses, including (1) three-stage treatment baseline scenario; (2) AD process project scenario. In addition to GHG emission estimation, the carbon deduction potential of the power generated by recycled biogas will also be evaluated. Ultimately, through this project we hope to establish a paradigm for carbon deduction policy making for anaerobic digestion of biowaste, and to facilitate circular use of livestock waste.溫室氣體;豬糞尿;厭氧發酵;減碳;生質能;greenhouse gas; pig manure; anaerobic digestion; carbon reduction; bioenergy
